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.

Planning on leveling my 2018 GMC Sierra 1500 with the MotoFab front 3" and rear 2" leveling kit. Planning on fitting 33" inch tires on my truck after. Trying to decide if I want 18" wheel rims or 20" wheel rims.. so if you could post pics of your trucks that would be great. Thanks!

Can any give some insight on which wires are connected to which speakers on the green plug. I have attached a picture. There are a total of 10 wires and I’m assuming they are (LF+/-)(RF+/-), (RR+/-), (LR+/-) 12V and ground but do not know which goes to where. Any help would be appreciated! Thank you!

I'm interested in a quick read of the room. How does everyone feel about the news that GM is moving in the direction of an battery electric truck? Does the brand it's sold under influence if you'd be interested? Are you ready to buy one now or do you think we should wait it out? Thanks for your opinions!

Chevy passed out a 2019 Silverado information book to journalists during this week's media drive. I'm working on scanning the entire thing and sharing it here. There's a lot of information packed into this flip book. I thought the most interesting was the engine line up and an AFM vs DFM diagram. This is the best comparison blowout diagram I've seen so far. Here's the four pages related to the engines.

John Goreham Contributing Writer, GM-Trucks.com 6-19-2019 If you are a fan of vintage Chevy trucks, you need to check out Wheeler Dealers Episode 3 of season 20. You can find it on the "Motor Trend" channel on your TV feed, or you can go to this link and watch it on your computer free (if you sign up for a 14-day trial.) GN-Trucks.com has no affiliation with Motor Trend. If you had "Velocity" on your TV feed, this is the replacement channel for it. As a fan of Wheeler Dealers who has seen every episode, I will warn you that this particular one is unusual in some ways. In many episodes Ant actually builds his own tools to do maintenance and repairs, and he even fabricates parts from scratch. This turnaround is more of an upgrade to an already awesome truck. There is a great transmission shop scene and the shots of the underside of the truck when they work on the suspension will make anyone living in the snow belt jaw drop. The truck is PERFECT underneath. We can't show you much more of the episode or even images without stealing from someone else's family bread, but you can see a quick shot of the truck in the image at the top of our page. Feel free to weigh in if you've seen it, or to chat about Wheeler Dealers in general. Just for the record, I loved Edd, but I am now also a big Ant fan (Makes sense if you know the show).

Recently purchased 3.0 JLT oil catch can. As I went to install it on my Silverado I honestly didn’t really see if it would fit so I backed off to get more info. Has anyone installed a oil catch can on the 2019 Silverado? The main reason for stopping the install was that the intake has some piece on the left holding it together that i can’t seem to find a way to get loose. I loosened the clamps to the air box and Intake manifold but some weird peice on the left is still holding it together when i attempted to take the intake off.

So, what do you think of the newly announced Blazer? Good choice for the legendary name? Bad use of badge you once loved? Let us know.

Did you know you can upgrade your gauge cluster in your 2014-2020 Silverado or Sierra? We recently did just that on our 2019 Silverado LTZ which came from the factory with a "mid-level" gauge cluster.

Zane Merva Executive Editor / Publisher - GM-Trucks.com October 8th, 2019 Chevrolet is ready to race the 2021 Colorado. Like, really ready to race. This week in fact. The new face for the Colorado mid-size truck will make its public debut October 10th during the 2019 Method Race Wheels Laughlin Desert Classic and will be driven by Hall Racing. Here's a sneak peek at the all new face of the Colorado. Chevrolet also gave us a showing of the production 2021 ZR2 that will debut in one month at the 2019 SEMA Show in Las Vegas. Check back with us in November for our first hand take at the new ZR2 when we visit the SEMA Show. Anyways, let's take a look at the changes. What's new with the 2021 Colorado? First off, the changes so far seem to be cosmetic and packaging only. No new features or changes in specs have been announced yet. However, the exterior has been warmed over to bring it in line with the Silverado's front end, without breaking the bank on a full redesign (which is expected in the 2023-2024 MY time frame). Here's the announced 2021 changes. New front end appearance for ZR2 model. Only Colorado model to have "Flow-through Chevrolet Fascia". WT, LT, and Z71 trim levels will receive updated center bars, lower fascias, and new front skid plates. WT and LT will feature "all-new" gold Chevy bowties while the Z71 trim is adorned with a black bowtie. All models receive embossed 'Chevrolet" tailgates and ditch the traditional bowtie on the rear of the vehicle. A new "Sand Dune Metallic" will be offered on Z71 and ZR2 models only. What do you think about the new face of the Colorado?

Now that owners are taking delivery of the new 2019 Chevy Silverado and GMC Sierra, I thought a quick reference guide to common routine maintenance items would be beneficial to us all.

Alright everyone... now that we've seen what the all new Sierra will look like, I think it's time for a good ol fashion'd vote down. Which truck do you like best? Which one would you buy? Which design do you like better? There can be only one! Place your vote now. VERSUS and of course, this is all just for good fun.

Hello, im currently in the market for a new (to me) truck. I have a little girl, and a fiancee. Ive looked at many truck for sale. The biggest features im looking for is, 4door, leveling kit, tint, somewhat low miles, wheels and tires are a plus, but not nessicary, and well maintained. I know truck pricing in general is pretty high nowadays. But i made this forum to ask, what would a good price be for a Silverado between 2014-2016 be? Thabks in advance

Hi, I'm pretty new to this website. Came across it when I was looking for an answer to my problem . . . I don't know too much about trucks.. cars....4 wheel vehicles. I just bought this 06 crew cab 1500 silverado 4.3L had about 80k miles on it. I actually noticed the sound when I was test driving it from the dealer. Now it has about 101k miles and noise is still the same. it makes a rattling noise, almost like a metal noise at LOW rpms only. Doesn't matter if its 35 or 75mph. Have to be cruising like slight amount of acceleration. Sounds like its coming from the engine.. I checked a bunch of forums all saying different things. my truck is stock, as far as i know.. one of the forums mentioned it could bea bad alternator, but I have no clue. any help? Sorry I'm a complete noob. Ivy

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.

In between packing up our house to move and work I finally found time to pull together my review of the Bumpershellz I installed on my Sierra. I picked up a set of the bedlined bumpershellz for my GMC through the recent group-buy we did on the forum a while back. Side note, thank you to everyone who participated, it was fun. First impression, these things are badass!!! The bedliner was an excellent choice. I was back and forth between doing a PTM or the bedliner, glad I went with the liner version. I have installed body accessories in my tuner days (think, front lips on Civics) and was fully expecting to have to modify the shellz to fit my truck because body panel accessories never fit. These fit right out of the box making life REALLY easy. One note, the adhesive is really tacky so like Eminem says, "You only get one shot, do not miss your chance to-" TEST FIT! TEST FIT! TEST FIT! Final verdict: I would without a doubt install these again if I needed to. Anyways here are some pictures of the final product and my Youtube install video. Water Fowler junior wanted to help and shows that even kids can do this install. Installation sparknotes for the laz: Clean bumper Wipe bumper with isopropyl alcohol Install blackout tape Remove adhesive backing Slap the shellz on the truck Sit back and admire Enjoy!!!

Hey guys, I have a 2017 Silverado High Country and I installed a 6in Fabtech lift with 35in nitto tires back in September 2017 and since then I've been having issues with my cruise control disengaging/turning off at anything above 69mph. When I'm traveling above 69mph, cruise control will turn on and illuminate on the dash, but it wont engage or lock on. Even when I have the cruise set at 65mph and I try to increase the speed to 70mph, it'll immediately cut off/disengage. I took it to the dealership around January 2018 and they told me since the truck has bigger/heavier tires, the computer is reading the wheels going slower than what it reads on the speedometer. They basically said I need to recalibrate the computer to read the new tire size. BUT, a friend of mine also said I could possibly need to re-gear to 4.56 since I'm running heavier tires, which could fix the cruise control cutting off. If anyone has experienced this issue, you help will be greatly appreciated. Thanks guys.

Zane Merva Executive Editor, GM-Trucks.com 9/25/15 When Chevrolet spilled the beans on the 2016 Silverado yesterday at the State Fair of Texas, a curious detail stood out to us. Silverado is saying goodbye to the halogen headlamp. Even base WT models will now come standard with HID headlights. A 2016 Silverado WT with standard compact HID headlights, LED DRL, LED Turn Signals, & LED Marker Lights LED's (Light Emitting Diodes) are also being deeply ingrained into the model. LED daytime running lamps, turn signals, and marker lights will be standard on every single Silverado, including work truck models. LT trim levels will be able to opt for LED fog lights and LT Z71 and up models get them standard. LED headlights also come standard on LTZ and High Country models, matching the LED offering by Ford in the new F-150. This addition of next generation HID and LED lighting will modernize the exterior the 2016 Silverado. It will also set the Silverado apart. No other automaker, including Ford and Ram offer HID headlights on their base work trucks. All the other standard LED stuff is just icing on the cake and a competitive advantage for Chevrolet. . And this is just the beginning. Expect other Chevy models to receive the same full-LED treatment in the next two years. What do you think? Will offering more standard LED and HID lighting than the competition equate to a sales boost for Chevrolet?

Do the 2019 GM Step Assists fit the 2014-2018 model years? Trying to figure out if the 2019 Sport Steps will fit my 2016 Silverado. Thanks.

Okay, i recently bought a 2in leveling kit for my 2017 silverado 1500 ltz and ive been doing some research before i get put on. i keep seeing people saying that you need to replace your shocks with larger one? and suspension system? Is this really true for just a 2in leveling kit? and if so how big of shocks do i need and what suspension parts need upgraded too..

I recently acquired a 1951 Chevrolet 6100 missing its engine and would like to refurbish it. However, Instead of putting in the original engine (Chevrolet 235) I am looking for an engine that came out in the next 10-15 years to put in my truck that will out put 200+ horsepower without being out of touch with the truck. Any advice would be greatly appreciated.

Hello all, I have a question in regards to replacing a block heater cable. My LLY has been garage kept it’s entire life and has never needed to be plugged in. Recently got an L5P l, so the LLY is parked outside. Went to plug it in today and noticed the block heater cable was rubbing onto some engine components which made it tear pretty much all the way through. I’m assuming the heater itself is fine, so I’d rather not replace the whole unit, rather the cord. Do you simply just unplug the old and plug in the new one behind the passenger wheel? Any recommendations on what cord or where to buy? OEM? Or will something from an auto parts store do the trick? Read a lot about splicing, I’d rather have piece of mind that I have a new properly functions cord.

Hello everyone. I have a fun issue. My 99 suburban decided to die on me recently. Was running alright. Went into my parents for maybe 30mins. Came back out it fired up and then died maybe a half second to second after. Never had the issue before. Today decided to attempt to diagnose. It has spark. Distributer looks good. Changed the fuel pump with assembly and fuel filter. Also changed the cam sensor and crankshaft sensor. Lastly changed the ignition switch due to sometimes it acting up and messing with my gauges and transmission. Checked the idle control valve motor. Seems to be working. Cleaned the gunk off of it and the throttle body. Checked all the relays. All working. All fuses are good. Attempting the security passcode reset now due to running out of options. The security light isnt showing. But not sure if this suburban has one. Spray starter fluid into intake and it will run for a second longer then dies out again. Not sure what's causing it. thinking maybe fuel pressure regulator. Any ideas?
