  1. Sorry for the simple question. I have a 2020 Silverado 2500 HD and I cannot figure out how to get the cab mounted cargo light to come one. The obvious button that illuminated the permitter lights, in-box lights, and tailgate light doesn't seem to turn on my cab mounted (up with 3rd brake light) cargo light. Am I missing something or is this another delete from gm (e.g console storage, read map pockets,...)
  2. What suggestions or advice is available for buying a GMC | Chevy truck? What should I watch out for -- the GOOD and BAD? I want to come back to the GMC | Chevy family. For over 20 years, we owned a 98 GMC Suburban, putting over 230k miles on it myself, and I LOVED that truck. Other than typical wear and tear -- I never had any problems or issues with my Suburban. I am looking at 2016-2022 -- GMC | Chevy 1500 | 2500 series, all trims (4x4), except the base models. My budget is around $35k plus'ish; yes, I understand my budget limits what I can get. I am a USAF retired veteran living off a fixed income. Yes, we tow hitch pull RVs and various trailers, but not as often as before. What are the GOOD, BAD, and UGLY these days on the GMC | Chevy trucks? Is the additional price for either diesel and/or 2500 worth it? SHORT STORY: so, a few years ago, I bought a 2015 Ram 1500 4x4 EcoDiesel 6cyl w/turbo Lonestar -- well, I have been disappointed with Chrysler | Fiat (FCA). They lied about the EcoDiesel, and after forced recall ECM updates, they sucked all performance and mpg from the truck. Buying a newish GMC | Chevy, I do not want to fall into what happened with my 2015 Ram. When I had my suburban, I never had so many recalls, been lied to, and never had poor performance. Thanks for any suggestions that you will provide -- Gary (ExFalconFxr)
  3. 06 Silverado 2500hd 6.0 My Silverado is getting really hot while towing up hill, to the point that the "Engine Coolant Hot" light is coming on. (Which I stop and let it cool down). This has gradually gotten worse. Truck does not get hot while towing on flat terrain. Any ideas?
  4. Picked up a 1996 2500 2wd silverado. Currently has LT245 75 R16s I have a set of LT265/70R18 on rims from a 2015 silverado 2500. Is there a website or someplace i can see if these will fit my pickup? I appreciate all the help you all can give.
  5. Thom Cannel: Article & Photos Zane Merva: Photos & Video GM-Trucks.com June 25th, 2019 By now you prospective 2020 Chevrolet Heavy Duty owners are over the Ho-Hum of our 2020 Silverado 3.0-liter story (we are totally Ho-Ho-Ho and Hmmm, can’t wait for a longer test!) and looking at the Alpha Dog, the 35,500-pound tow-rated Silverado Heavy Duty and its over 50 industry firsts including an updated diesel engine and all-new 6.6-liter gas engine. Let’s get to it. Where to start? With its amazing trailer towing features that include 15-view camera and ability to memorize the features of five different trailers? How about the Durabed with its class-leading cargo volume and all-steel construction with a plethora of cargo tie-downs? Maybe you’re gobsmacked by the corner and bed steps with, now, plenty of toe room and 500-pound weigh-holding capacity? Is it the power tailgate that remotely lifts or lowers? An ability to hold first gear while towing maximum weight? Or, is it all of these? Chevrolet states that Heavy Duty trucks are working vehicles, whether towing a gooseneck horse trailer or flatbed and whether gas or diesel-powered. They further tell us that, compared to light duty trucks where 84-percent are retail and 12-percent go to fleets, Heavy Duty buyers are 70-percent retail and 30-percent fleet. Further, Work Truck and Custom trucks make up the volume; LTZ and High Country capture an even larger share of the market for personal and dual use buyers, with mid-trim LT trucks straddling fleet and personal use. Hence the five available trim levels to suit the needs of every buyer. There is no mistaking that the 2500HD and 3500HD is kin to the 1500, yet only roof sheet metal is common. Everything about the new HD trucks was designed to be functional from larger grille to lower side-height bed, to improved box and bed steps. It’s massively bold with strong character lines, huge fender wells and functional hood scoop. Both the 2500HD and 3500HD are distinctive and clearly Chevrolet. For 2020, every frame is boxed and steel, there’s a model with built-in gooseneck cross-body reinforcements and bed holes, 4X4 models can option Autotrac two-speed electronic transfer case, the DEF tank is relocated inside the frame rails with the filler under the fuel door, plus a 10-segment DEF gauge measures content. A statistic to toss off at your microbrewery; within the total HD segment, 54-percent are Crew Cab diesels while within fleets, 62-percent are gas-powered, with 34-percent of fleets buying Crew Cabs and diesel power. And if you’re wondering where the 2020 Silverado HD you’d like to scope out on your dealer’s lot is hiding, Crew Cabs began delivery last week with Regular Cab, Double Cab and Duallies hitting the streets this fall. Restrain yourselves. Let’s now talk about the biggest reasons for owning a Heavy Duty Chevrolet (or GMC). It’s towing. And if you’ve noticed comments to our 15-camera article, there’s some passion about technology. Realistically, as many HD trucks are sold to new truck owners towing large RVs, anything that improves road safety is flat wonderful. If you further read Chevy’s research that says 12-percent of pickup drivers have gotten into a fight with their significant other over trailer hookup, you’ll understand executive chief engineer Tim Herrick’s comment that “We save marriages.” Having driven every truck segment from light duty to tractor-trailers we feel you. So, when research says a majority of drivers are stressed by towing, please offer them a 2020 Silverado sales brochure and a tissue (and save a tissue for yourselves ‘cause you might be exaggerating your tow-cool). So let’s dive deeper into the subject. Everyone has a hitch camera these days, with overlaid guidelines to put you within a few inches, front-to-back, of the ball. Chevy goes further with a selectable view that looks own over the ball. Even those who haven’t set a hitch in years—or never—can get within a quarter-inch of perfect. And an APB or automatic parking brake engages automatically so that when you lift off the brake pedal you don’t roll off the ball. Sticking with the non-pros and semi-pro haulers, there’s a checklist for your trailer, the ability to check the lights after connecting the trailer’s electrical system, a tow-haul reminder and VIN-specific labels for the trailer itself. If you option the smart trailer integration, which is designed to work with ASA Electronics iN∙Command® control system, you have control over trailer features like heat and air conditioning through the infotainment system or the myChevrolet mobile app. And nobody should turn down the ability to monitor trailer tire pressure and temperature. Blowouts are never convenient and most often low-pressure and highly temperature related, according to Michelin Tire Company. We found the 15-view system difficult to get used to during the first five minutes, particularly when backing; our mirror habits are embedded. Yet, simulating tight turns where we could see along both the tight and far side, pulling forward into a tight box, or backing (after a few tries), we really came to appreciate what the system could do. Then, on the highway with an 18,000-pound box trailer behind us, mirrors just didn’t cut it compared to the high-tech camera system. We were driving on twisting two-lane blacktop in mountain foothills. Using the entire camera tech set, particularly the ability to look out the back of the trailer, we could easily pick places to pull aside to let faster cars pass us. It took less than an hour to become a must-have feature. Later we towed a smaller skid-steer on a flatbed without the system and truly missed it despite using our slide-out mirrors fully extended. This naturally leads to the two engines offered in the 2020 Heavy Duty, first the 6.6-liter V-8 purpose-built gas engine that delivers 22-percent more torque than its predecessor. Now it delivers 401 horsepower and 464 lb-ft of torque. It’s mated to a six-speed automatic transmission. The 6.6L isn’t a just a 6-mm stroked 6.0L, rather it takes advantage of the Gen5 small block architecture and has a unique cast iron block with forged powdered-metal connecting rods and forged crankshaft. The most significant change is the addition of Direct Injection. It’s all new, an industry first for the heavy-duty market and new to GM trucks. Direct Injection allows a compression ratio of 10.8:1 Quoting Mike Kociba, a GM engineer and part of the Small Block team, “Our suite of changes allows us to hit class-leading gasoline engine torque, at 464 foot-pounds at a lower engine speed than the outgoing six-liter was optimized for. I'm proud of its 401 horsepower, which is SAE Certified; no games, it’s legitimate. Customers can have confidence they're going to tow whatever trailer they need.” Don’t forget the larger cooling fan and newly designed water pump. The pump drives the fan through a one-inch shaft with unique bearing design to handle greatly increased thrust loads. Plus, the oil pump is now has variable output, so there’s less parasitic losses. The 6.6L engine features an aluminum oil pan, nylon 6-6 air intake, and stainless steel exhaust manifolds unique for the Heavy Duty market. Like related light duty Gen 5 motors, this motor has variable dual-equal valve actuation, massive Gen5 valves and uses an actuator that’s mounted to the front cover to control intake and exhaust valves. The new block features inter-bore cooling, that is, coolant flows through Siamesed bores, notably in the upper bores where there’s a tendency to generate higher temperatures. “Small engines with turbochargers allow them peak torque off idle,” Mike told us, “but for heavy duty we don't want that complexity. For the Heavy Duty segment we (General Motors) have durability requirements—Global Engine Durability—that are unique stringent. We know our customers and why we focus on durability. If they can't use their truck today, they might not get paid.” When towing a heavy load, we loved the diesel’s engine braking capability. What about the gas engine? In Tow-Haul, up-speeds caused by downhill driving—together with intelligence based on throttle position—the powertrain produced seamless downshifts. It’s not quite the same as engine braking, but the trailer was “only” 12,000 pounds. Regardless, it was a comforting addition to stress-free towing. The six-speed transmission used for 2020 Heavy Duty GM trucks is an updated 6L90 with an uprated torque converter and clutch pack. According to GM engineer Rich Mardeusz those changes were simple. When it came to the torque converter, things changed. “We looked at the components from a heavy-duty diesel torque converter and a high-output gas torque converter and then took the torque-carrying components from the diesel and married them to the spring and damping components from the gasoline torque converter. That’s what was needed to accommodate the approximate 22 percent across-the-board torque increase.” Those changes also damp out firing frequencies from the gasoline V-8 engine, making the powertrain smoother. Since a majority of buyers opt for the diesel engine, let’s look at that. Also displacing 6.6-liters, the Duramax turbo-diesel makes 445 horsepower and 910 lb-ft of torque. It’s coupled to a 10-speed Allison transmission. There were minimal changes to the engine for 2020. They include a 28-inch fan for cooling; upgraded oil cooler—now 19 plates instead of 14 and the cylinder head gasket was improved. Engine brake capacity is greater by 14-percent and while there’s a button for manual activation, while in Tow-Haul mode engine braking is automatically activated at certain RPMs. It’s Chevrolet keeping you safe. Thus, under the new control system the powertrain will recognize any need for the engine brake and activate automatically. For instance in driving down hill and forgetting to shift, the higher RPM means automatic activation. We did experience this with the18,000 pound box trailer and it is amazingly transparent and surprisingly quiet. You don’t have to downshift on modest hills, as the system will totally keep you at, or near your desired speed. Of course you may have to use a bit of smooth brake application if the grade is longer, or steeper. For really steep downhilling Plus-Minus buttons on the column-mounted shifter initiate gear changes. We’re not huge fans of the buttons as the steering wheel obscures their location and make it a bit fumbly to slide your thumb into position. A really important feature for 2020, diesel models add an engine after-run feature. Should you tow up a grade and park for dinner without a cool-down, the truck will do it for you. Run time is limited by temperature and shutdown is equally automatic. Because of the Allison/GM 10-speed transmission used for 2020, the powertrain required a complete recalibration. There are several positive results, according to David Ames, GM assistant chief engineer and Allison liaison. “Emissions have been improved and fine-tuned to maintain the best efficiency the transmission can offer to our customers.” It also has a fully warranted chain-driven engine-speed PTO available from the factory. The new 10-speed’s torque converter has a lock-up clutch that is unique as it will lock up in first gear, even under max loads. So, if you're pulling 35,500 pounds, you can do a first gear launch and lock up right away, which helps get rid of heat. We asked David why this is important. “Normally in first gear you're under high torque and generating a lot of heat, which puts a lot of demand on the cooling system. Locking up gets rid of that heat. Also, the new transmission has a lower 4.5:1 first gear with four planetary gear sets and six clutches. We noticed the low gear and ten speeds on launches and while pulling the box trailer on the highway. Often in hilly driving you're downshifting to save brakes; with ten gears we held the right speed and best RPM, particularly with automatic engine braking. We did drive a Silverado 3500HD dually at max capacity; 35,500 pounds on a closed course: our US Army CDL permit has lapsed. The claim of off-the-line torque is spot on. What was most interesting was the 3500’s ability to resist being pushed about on turns and we did several random serpentine loops to see if we could find any significant push? Nope. Later, with “only” 17,000 pounds behind us we finally found a bit of trailer push, which required a deeply rutted dirt road and an off camber turn. Nothing the truck couldn’t handle, even with a journalist behind the wheel. Many of us wondered why the different transmissions for Heavy Duty trucks, why not just the Allison ten? We asked and, while suspecting that plant capacity utilization and raw costs have something to do with it, were told by Vincenzo Verino, the 3.0L Duramax global chief engineer “It’s really about what the transmission brings to the engine itself. With a wider torque band, the gas engine is well-matched to a six-speed, while the narrower torque band of the Duramax is better suited to a 10-speed.” In the battle for Heavy Duty supremacy, big numbers are thrown around to convince potential buyers of worth and value. We found these slides from Chevrolet’s presentation compelling, showing Chevrolet doesn’t always have the biggest power numbers, yet can deliver more real world competency than competitors. Faster to 60 with better towing capability, we’ll take that over a bigger number any day. And Chevrolet says every diesel dually will tow more than 30,000 pounds the 2500HD with 6.6L gas engine has a tow capacity of 17,400 pounds, up 18-percent, that’s good regardless altitude. There is much, much more to tell in future stories, like the no-cut removable fascia for winter snow plow installation and the covered fender-mounted engine heater outlet, use reports of the up-down power tailgate and the bed’s 12 fixed and 9 moveable tie-downs. There’s details on improved axles, locking rear differential, beefed-up prop shaft and 12-inch ring gear, stronger U-joints, class-exclusive SLA front suspension (“mandating a solid front axle for HD trucks isn’t a thing” according to the chief engineer Tim Herrick) and the list goes on. We expect to write several more stories about the new trucks, each specific to how you’d use the truck and with even more details. We have only scratched the surface.
  6. Hello guys & lady mechanics, I’m in the process of replacing my rear disc brakes, it has 4Wheel anti loc disc brakes. I have the rear rotors with the interior surface for the parking brake shoes. I have new rear backing plates and hardware. But I noticed a little bit of a runout in the axles, I’m assuming it’s normal bearing wear. It has 175,000 miles on it. Plus the brake lines rusted and caused a pedal to the floor issue for me, so I replaced every single brake line with all new stainless steel lines, and new brake hoses. It has new rotors and pads upfront. What I’m trying to find out, since it’s a 14 Bolt GM differential in the rear, what exactly do I have??? 1) Is it a 9 1/2 inch ring gear, 14 bolt rear end, or is it a 10 1/2 inch ring gear 14 bolt rear end? Where can I find this out. I need to order bearings and seals, and a pinion seal which is leaking. which is my next question, 2) how do I determine what size my pinion seal is before I order one? O’Reilly shows 8 options 3) Last question is, I’m assuming I’m going to have to pull the cover, remove the locking pin for the limited slip differential, and push the axle in, pull the retaining clip, and pull the entire axle out to get to the seals and bearings, correct? My plan is to put a new B&M aluminum differential cover and fresh fluid once this is all done… Lastly I wish I would’ve found this side or search prior to doing my brakes, I would’ve found out that GM was offering half off To replace all new brake lines for $500. It’s done now though. Happy holidays you’ll Dave
  7. So my wife went and broke the right passenger side mirror on the Avy. They are the power extending style and of course they only extend and retract manually! What are my options for replacements? I hate these mirrors anyway but now I got a reason to change em out! I love the 07 and newer style HD mirrors on the GM's! Will these work on my truck? If not, what else would you recommend? I would love to install power folding tow mirrors using the factory power switch for the extending ones but I have not been able to find anything.
  8. Ok, I want to come back to the GMC/Chevy family. For over 20 years, I owned a 98 GMC Suburban, putting over 230k miles on it myself and LOVED the truck. I too owned a 2003 Chevy 1500...put many miles on it too. I am looking at the GMC/Chevy 2500 series diesel trucks. I will stay within the 2016-2019 year range, with about $35k plus'ish budget. I might look at the 2021 trucks, only due to many deals/rebates etc. What suggestions or tips are out there for these trucks? What should I watch out for and/or look at getting? So, a few years ago, I bought a 2015 Ram 1500 4x4 EcoDiesel Lonestar -- well, I have been disappointed with Chrysler/Fiat (FCA). Short story, they lied about the ecodiesel, and after forced recall ECM update, they sucked all performance etc., from the truck. When I had my suburban, I never had so many recalls, been lied to, and never had poor performance. Thanks, for any suggestions that you will provide. Gary
  9. My new truck has cameras all over it. Front, side, rear, top. I figured out how to remove the tailgate, even made a short UTube video to help others, but after removing it, I found out that the camera system does not work. I still wanted the front, side, and top cameras to work with the tailgate off. Has anybody else encountered this? Figured out how to keep them working with the tailgate off?
  10. A flat Good Year Wrangler SR-A set the tire shopping in motion, and a 10% off sale on Nittos convinced me to try the 35x11.50r20 Ridge Grapplers. My goal was to get as much tire as possible without having to adjust the suspension so as to retain the stock ride, keep costs down, and achieve the aesthetic I like for modern 4x4 trucks. I was prepared to crank the front keys a few turns for up to 1" of leveling, but my preference was to avoid this if possible. Ridge grapplers have two sidewall designs on the tire; one side reminded me of Transformers, so I went with the more subdued sidewall. This doesn't impact fitment. After about 20 miles of driving and some parking lot testing turning the steering back and forth, the tires fit fine with only a few close spots throughout the range of motion. I've seen people report frame rub at full lock with these sizes; it hasn't happened to my truck yet, but I wouldn't be surprised if it rubs mildly while turning sharply over rough terrain. Rear clearance is fine. A few tips: Check the actual dimensions of the tire you're choosing. The Nittos are 35s, but the actual diameter is about 34.7". Each manufacturer is a little different, and most list the true dimensions on their websites. The same applies to metric sizes - a BFG may be narrower than a Toyo. Looking at my truck, 35x12.50r20 would have fit too, but would probably rub on the wheel wells while going over bumps during a turn. The 11.50s provide just enough extra room that my truck has yet to rub, though my mileage count is low (20 miles since install) so I'll update this thread as I add miles. Expect to lose fuel economy. No data yet, but I anticipate a 1-2 MPG drop. Aftermarket wheels change everything. The popular offset or "poking" look makes it harder to stuff big tires without a lift. If you're changing wheels and tires, disregard this thread. What's next? Fresh oil, a detail, and maybe a front window tint. I'd like a Corsa, but they're $$$. Please excuse the dirty truck:
  11. Hello, Just bought this big boi recently and love everything about it but would like to upgrade couple of things 1. Do the sell Retractable Side Mirrors, I want to be able to when I turn off the car and lock it so that the side mirrors close by itself 2. Also would like to be able to press the little button on door handle to open the door instead of unlocking it. Does this exist for this model? Any links would be appreciated 2020 Silverado 2500HD Thanks
  12. I have a 2000 Silverado 2500 6.0 that is having some hesitation/cutting out on acceleration. It’s weird it seems like if you ease into the throttle it doesn’t cut out but if you mash on the gas it acts like it wants to die. It does it in park and in drive. First noticed it when I was pulling my boat out of the lake and I could barely make it up the boat ramp, it was spitting in sputtering until it eventually seems like it cleared up and started going normal. I replaced the spark plugs, spark plug wires, fuel pump, fuel filter, ran seafoam through the gas, and change the air filter but it seems to not of helped there’s also no check engine light. What could be the issue, thanks!
  13. I recently became acknowledged about the myth of the 3,000 mile oil change on newer vehicles with advanced oil. I own a 2006 silverado 2500 v8 6L WT and I change my oil every 5k miles with Mobil synthetic 5w-30. I cannot seem to find the exact information within my car manual or my Haynes/Chilton manual for the recommended interval between oil changes. Is there anywhere I can look up how often I can change my oil with the specific engine of within my truck? I have heard some oils can go 10k+ miles on some vehicles. I'd love to do less oil changes, but don't want to endanger my engine since oil changes are so quick though I'd love to save money too! Where can I find this exact information or do you have any other suggestions? Thanks in advance!
  14. New 2020 Silverado 2500 diesel, newly retired, bought truck to tow a travel trailer. I've been a GM customer and amateur mechanic for over 50 years. I had not driven a 3/4 ton truck for decades, when I test drove a new 2500 I simply was stunned by the ride quality, to say the mechanical engineers have made improvements would be a world class understatement. The power, ride quality and tow features (mirrors and cameras) sold me within weeks of shopping. The size is a little off-putting but after only 8 weeks I have compensated for parking and maneuvering a very large pickup. The truck draws some jokes about its size but I absolutely love the towing performance, it is a worthwhile trade-off for me.
  15. Posting my aftermarket tail lights from my used 2016 Silverado. bought LTZ tails from a member here, took these off as they were installed when i bought the truck last year. no damage, have had 0 issues with water or condensation. actually love these tails but id rather have the LTZ factory lights installed. light output is great. had them on a LTZ truck so im guessing these are the models for the LED trucks and im not sure if they will be 100 percent compatible with a 2014or 15 application. In any case there are threads here to make your own resistors or people who make harnesses if you run into problems, but i never did. willing to ship at buyers expense, but send a PM with a zip code so i can figure out cost of shipping to you. otherwise we could probably meet if nearby to DENVER, GOLDEN, or LITTLETON COLORADO. I'm posting this on the forum, local craigslist and other apps/sites just to move these quickly, but if they are sold elsewhere ill update the post as soon as possible. Would like to get 300 out of em but I'm also realistic so send me an offer and we can go from there. Thanks for taking a look at the ad, have a good day!
  16. The picture that shows 2500 and 3500 both they look better
  17. I BOUGHT A 2012 silverado 2500 in facebook marketplace but the person who had it didnt have the hardware/clips/bolts to put it together. He ziptied it together, I NEED HELP FINDING WHERE I CAN BUY ALL THE HARDWARE to assemble it properly! IN THE IMAGINE I CIRCLED WHAT I NEED
  18. Ok Members, Here is the all inclusive way to swap a GMC K2xx 1500 front bumper to a 2500 Front Bumper. This is for the Sierra only, the Silverado is/may be different. First lets start with what IS needed the part numbers if applicable. HD Grille (PN Varies ) HD Bumper assembly (PN varies) HD "headlight fillers"( GM list's them as 'Top Cap Assembly) --------LH PN 22831429 Paintable --------RH PN 22831430 Paintable HD headlight filler brackets ( GM lists them as Fascia Bracket assembly) --------LH PN 23451021 --------RH PN 23451022 ****I will also mention the Front bumper to inner Frame support brackets. I got them with my 2500 bumper when I purchased it, so I used them, and they work and fit great. Im sure but cant say for certain if the 1500 bumper for frame supports can be made to work. Once all the swap parts are acquired, then you can begin modifying the parts on the current truck The 1500 Bumper mounts have to be used. I attempted to try and use the 2500 brackets and the mounting holes are in the wrong location, as well as it makes the bumper sit way too far forward away from the truck, As for the 1500 modifications, the 3 mounting holes will need slotted so the bumper brackets can sit lower to accommodate the additional height of the new bumper. Reinstall the brackets and drop them down until they hit the frame. ***** I spaced my brackets up a bit off of the frame. I felt the gap between the headlight fillers/grille, and the bumper was too much. with a little spacing you can get the gap nice and tight***** I also used 3 additional washers behind the brackets to space the bracket away from the frame. With out the additional spacing the bumper sat too close and didn't align in the wheel well Once the frame brackets are situated, you can move onto the fascia brackets. they are a simple swap, unbolt the 1500 and swap them for the 2500 brackets Now install the headlight fillers onto the fascia brackets that were just installed. The headlight filler assembly's will also use a bolt location from the 1500 grille that the 2500 does not use. Now its time for the bumper. Install the bumper onto the frame brackets. The 1500 brackets will only allow the Upper hole closest to the grille to be used for attachment. The Bumper will fit pretty tight onto the brackets. As I said earlier I was able to use the 2500 Inner bumper to frame brackets , they were the correct length, and shape to fit around the frame Mounts The last big modification is the fender well trim. The 1500 trim is much longer as shown by the blue tape line. The trim needs cut on the bottom of the tape to align with the headlight fillers When it’s all said and done the top pic is the OEM 1500 Denali and the Bottom is the 2500 Denali Swap (yes I know the fog lights aren’t in but I was excited to take a pic)
  19. Might have a ridiculous question but I cant see the issue in theory so I am consulting the experts. I have a 2015 2500 HD 6.0 4x4. I recently had long tubes installed. First finding long tubes for this application is insane. I could not specifically find anything that guaranteed fitment for this year. I ended up with speed engineering stainless that was made for the 6.0 up to 2013 according to them it should carry over in later years which is true given the L96 has changed little to none. I had zero fitment issue with the passenger side but the left was awful...... hit the motor mount, frame, and drive shaft. I had the shop modify the header to fit......being honest he did exactly that and I'm impressed but I believe the header is leaking like nobody's buisness due to the 8 different cuts and bends he made. and makes an awful sound I do not feel like going through hell and back or spend the money on another long tube header for that side to run into the same issue...... so what if I ran a shorty 1 7/8 stainless on the driver side and a 1 7/8 long tube on the passenger side? It's off the wall but why not? If the true duals x and I have a custom tune in theory it should not be an issue right?
  20. hey everyone, I know I'm probably out of luck on this, but I am wondering just how different the rear frame is between a 2014 1500 and 2500. I am looking at the Ultimate Air Ride kit for the back, but they only have it available for 2500 and 3500. I know the frame is taller, but haven't been able to find how much so. and if there is any difference in the axle tube size of the rear diff. I know there will definitely some modifications to the brackets required, but I'm trying to see if it is feasible to try to adapt their kit or if it isn't worth it. or if anyone knows of something similar, not like the Air Lift load leveling kits, for the 1500's. I love having my truck lifted, but it would be nice to make loading my bikes and toys easier as well as the load leveling with a trailer.
  21. I have a 99 silverado 2500. Has middle fold down seat. I want to put center console and seats with arm rests in like tahoes had. What years and seat would work. I want cloth seats.
  22. Hi, I have 2 questions. One, I want to do the HD Front end conversion on my 2007 NNBS Silverado1500. I know what I need, and I have decided on the 2011-2013 HD grill and bumper. I have gone on line and seen some people go with the 2007-2010 HD hood and some people go with the 2011-2013 HD hood. Would any one know the difference or if one fits better onto the 1500 truck? And does anyone know how to install the bumper? And the second question was, How can I convert the truck into full electric mode? I have manual windows and no power locks. My truck is extended cab and I would wish for the back windows to work as well. Or does anyone have a really good video on what parts I need and how to do it step by step? I am by no means a mechanic but i do work on my trucks here and there on small things. Thanks in advanced!
