  1. 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.
  2. Good morning everyone, I recently purchased a 2018 GMC Sierra Crew Cab SLT All-Terrain package. I'm personally wanting to install a leveling kit and I believe I've selected one. I've read a lot about leveling kits for 2017-18 trucks and this seems like a great kit. However, there isn't many reviews on this product by ReadyLift. The appeal of this lift is the UCA replacements and the <2" height it allows. I'm wanting to go with 305/55/20 or 285/60/20 tires with my stock AT wheels and I want as much clearance possible. I found maybe 2-3 members on here with this lift and I'll quote them below. My question is, will this work with my All-Terrain package? In the description of the kit it states, "Will not work on Z71 packaged vehicles with factory Rancho® struts." Yet on ReadyLift's website, there is nothing supporting that statement. Does anyone have any information or review for this kit? Thanks!
  3. Has anyone had a rear compressor issue with a new Yukon XL Denali? My wife and I bought the vehicle at the beginning of October 2018 and within a month the rear compressor began running excessively. We took it into the dealership with bought it from and the service rep heard the noise but was unable to reproduce it later in the day with the technician so they sent us away with the vehicle. The noise became more and more regular so we took it to a dealership near our house and they heard it and acknowledged the problem, this lead them to replacing the rear compressor. The change of the rear compressor didn't do the trick and the excessive running persisted, this is where the frustration really set in. The service technicians were going to run diagnostics and service the vehicle after we brought it in MLK Day. The service department manager interrupted the process and essentially tried to bully my wife into accepting the fact that this is normal behavior for a GMC Denali line vehicle. She left the dealership in tears. I called the service manager in disagreement with 1) his treatment of my wife and 2) disputing the fact this is normal. His response was the discharge the video with a bogus report emphasize the vehicle was in intended working condition. Now the Denali is sitting at another dealership while they try to replicate the issue. It occurs 30-40% of the trips we take in the vehicle and the rear compressor will run anywhere from a few seconds to 20 minutes. Has anyone else had this issue and found a resolution? I'm to the point I'm almost willing to just sell the vehicle back for a loss to be rid of it.
  4. Thinking about adding 2 or 3 small leds in the ram air hood scoop. Guy on another forum did it on a Silverado but this is the only one I have seen. https://www.google.com/amp/s/www.dieselplace.com/forum/76-speciality-forums/81-electrical/951082-2017-hood-scoop-lights.html%3famp=1 May be too many since I added running board lights though...
  5. Its been awhile since I've put up an update post on what I have done to my truck in the past few months. So here is the list.... -RC 2 inch leveling kit -Carven performance exhaust ( Competition muffler ) -Aftermarket taillights ( returning soon as they already have issues ) -future planned taillights are morimoto's -Black bowtie swap front and rear -I may get aftermarket headlights in the future if prices go down. -Custom HD towing mirrors ( The front LED turn signals are sequential ) -20 inch light bar mounted onto a license plate bracket mount -20x10 -25 offset dropstar 655bm -33x12.5 toyo open country RT's -Front end air dam removal with trimming for tires -LED turn signal bulbs All these mods were done myself except for the tow mirrors since i had them done at my Chevy dealer so that i made sure everything worked properly and was warrantied for the wiring harness. Please give me your thoughts and opinions on my build and give me any pointers o what i should do next to the truck. I'm thinking about getting a cold air inductions CAI next.
  6. Zane Merva Executive Editor, GM-Trucks.com 10/30/18 Day one of SEMA 2018 is almost already in the books and we've barely made it through the South Hall (which houses the Truck/Off-Road section) trying to get our eyes on every customized 2019 being shown inside exibitor's booths. There's no way we'll see everything but what we have seen already is impressive. Accessories for the all new Sierra and Silverado are coming out in force, even if the trucks are still trickling into dealerships. Although the new fullsize pickups are GM's hot new thing, the automaker has not made it a focus of this year's show. That means, while we're seeing a ton of 2019 Silverado and Sierra, there are 2x as many 2019 Dodge Ram and 5x as many Jeep Wranglers. Here's what we've seen so far. We'll add more photos to this thread as we take them.
  7. I have a 2018 GMC Sierra 1500 Denali. I just installed the 2” Rough Country front leveling kit. I couldn’t do the 2.5” because my truck has the stamped control arms. The rear of my truck still has about a 1.5” lift/rake compared to the front that I am sure is caused by the rear lift blocks since it is 4WD. Can I remove the rear blocks safely? Or will it cause any damage to my Magneride suspension? What are my options to lower the rear to match the front of my truck now?
  8. Zane & Josh Merva GM-Trucks.com March 12th - 16th, 2018 As attention starts to shift from the current generation of K2XX based Silverado and Sierra to the all new 2019 T1XX based trucks, it's all too easy to forget just how far we've come and how much General Motors has "perfected" these tools over their last generation. Case in point, the 2018 GMC Sierra Denali. It's the company's most luxurious pickup ever. (Well, at least for a few more months). When the opportunity to take this generation Sierra for one last spin presented itself we jumped at the chance. A week behind the wheel of a 2018 right before the 2019 models started to hit the ground sounded like a perfect refresher. Each day this week we'll share our time, photos, and thoughts about this range topping model. Being that it's a Denali, it has... well.. everything. From the high-powered 6.2L V8 to the rail-like magnetic ride control and the plush heated/ventilated seats, this Denali has all the goodies to compete with pure luxury sedans from the likes of BMW, Lexus, and Audi. Stay tuned all this week as we add our thoughts and a slew of images to this thread.

  9. 2018 Silverado Z71 5.3L with 14K miles. DIC fuel average indicates 10.3% better fuel economy then actual MPG. 28 fill-ups and reset each time. Any way to calibrate meter? 1% variance maximum variance between each of 28 fill-ups. Thanks for any assistance. Truck is 100% stock including tires.
  10. Hey guys so I did a 2019 Frontend Conversion to my 2015 Denali, with the Ram-Air style hood..... But trying to find a wire harness that converts from 2015 to the new lights, well that's easier said then done. So I was given this site by a friend that did this conversion to his truck.... I highly recommend this site, as they use GM plugs & the wires are all as good or better than stock..... Nothing wrong with that in my book. Check them out, they have E-mail if u have any questions & in my experience they get back to u in like an hour or less...... These harness are truly "Plug & Play". No cutting any wires, no guess work, all that is done for u.... They have the schematics for all the years & work off of them to make sure everything is correct.... Plus they check everyone before shipment..... Pic of my Denali, before & after. Their website also include. https://www.gen5diy.com/collections/14-18-sierra-p-p-harnesses
  11. Hey all, I own a 2018 Silverado 2500HD LTZ Z71...The damn headlights are that terrible yellow color, Did Chevy not put LED lights on any of the 2500 models? Has anyone replaced the whole light assembly or even just bulbs to achieve the clearer look? If so please share and checkout the photo below of my headlights compared to the illuminated bow tie. Thanks for the help.
  12. I am wanting to trade in my 14 silverado 1500 for something thats rated to pull more weight. I notice on Chevrolet's website that the commercial silverado 1500 w/ 3.73 rear axle ratio has a 15000/16700lbs w max trailering package rating. Every dealership I've called doesn't know what I am talking about so can someone verify for me that this configuration of the Silverado exists?!
  13. I just purchased a new 2018 Silverado LT Z71 4wd crew cab short bed and am planning on putting the zone 4.5" lift kit on the truck with fox shocks. I love the look of deep dish rims and am leaning toward Hostile sprockets. I am wondering 2 things. 1. if going with a 20x12 on 33 m/t and -44 offset, how much cutting would be involved to solve the rubbing issue and would those cuts be visible with the wheels mounted from the outside? 2. What is the meatiest size someone would recommend for the Hostiles on 33's without having to cut and without rubbing on the 4.5" lift?
  14. Just got a new 2018 Sierra with more bells and whistles than I've ever seen in a truck before. Sure learning a lot on these forums. The catch can thing has my interest, I never even knew that was a problem, never had a direct injection vehicle before. I'm looking under the hood on this thing and although it is difficult to see much it looks like there are two PCV valves, assuming that's what I think I'm seeing. They are right up front of the engine, one each side, with short tubes going into the intake air plenum. See attached photo of the front left side of the engine. So question #1, are two PCVs what I am seeing? Question #2, if so then I need either two catch cans, or one that does double duty, right? I'm a little confident that the answers to my questions will be yes (still appreciate confirmation though) and if so this will be a plumbing nightmare. This truck has the eAssist which means the only open space for a can is the front left corner where the battery used to be, on eAssist it's up in the back right corner of the engine bay. And, there is no room at all left in that part of the engine bay, it is packed. So I guess question #3 is, anyone come up with a creative way of solving this problem, besides hoses all across the top of the engine? Thanks in advance for responses.
  15. Just purchased a 2018 z71 after the torque converter died on my 2015. Really like the newer front end, however I have noticed a lot of wind noise from my drivers window vs my 2015 model, anyone seen this issue?

  17. Coming home from a four-hour trip Sunday towing a small utility trailer, my truck dropped to idle while at speed on the interstate just a few miles from home. I was lucky and able to pull over to an exit ramp with zero power. While coasting the display popped up saying reduced power for a couple of seconds and the engine light came on. While still on the exit, all power restored, message went away, and I was able to make it home on back roads. While it was still running I pulled three codes: P0087, P129F and P228B. Cut it off, unloaded everything and then went to move the trailer. It turned over for a few seconds then busted off (longer than normal). As soon as I put it in gear it shut off. Got it to the dealership and awaiting the results. Truck only has 1,404 miles on it and was delivered from Flint a few weeks ago. All displays read fine, fuel filter, DEF fluid, etc. Engine light still on. Just FYI to add to the list of L5P problems
  18. Well, seeing as how I can't find much on this subject no matter what forum I go to, why not try to start the discussion here and see what kind of following I can get and see where we end up. If you're reading this thread, chances are you have thought about modifying or swapping out your current transmission in your 2014+ GM truck. In my case, I don't mind my 6L80 in my truck. It does fine for what I do right now and it's holding up just fine, but I think the big issue is when you start to search for big power (like I'm starting to do), that 6L80 is not going to hold very much (or so we think). Now, let's all face it. We've seen posts after posts, comments after comments, photos, videos, etc. of guys with built motors with turbos or prochargers shooting down the quarter mile in search for the best time on these 6L80s. Some say they're completely stock, others have them built, and we all ask ourselves the same question: Reliability. How well are these transmissions going to hold up to the abuse on the track? Especially if you want to make it a fast street/strip truck and drive it back home to the garage afterwords. We know for a fact that 6L90s can hold quite a bit of power. Even though I've mostly seen it in Camaro ZL1 applications, there is a guy on YouTube (GuitarmaggedonZL1) who is running a stock 6L90 on stock converter making 1000HP (give or take on an unloaded dyno) and the transmission hasn't puked all over the ground just yet. (Exaggeration, I know.) So, needless to say, a 6L90 swap sounds nice, at first... After you figure the extra length and weight (and in my case, relocation of the transfer case and getting custom driveshafts made), it starts to look a bit unpromising, but still not out of the ball park yet since it will be able to handle the power some are seeking, but where these newer transmissions lack significantly if you want to do boosted applications at the track (or even just launch control on N/A), no one has developed a transbrake. Very, very few forums are talking about this, and only one video exists of a guy in his BMW testing out a transbrake on a 6L80/6L90, and who knows how reliable it is. So, now, you start to think: Well, gee. What can I do now? How about a TH400 or 4L80e swap? So far, I've seen few posts on that as well. No one is talking about it, and I think the biggest problem people seem to be facing is the new PCM: E92. Also possibly the fact that the TCM on the newer transmissions is inside the transmission and whatnot, but whether that plays a part in this, I don't know yet. Now, adapting a TH400 or 4L80e can be done (most likely with a different bellhousing since the bolt holes are in a slightly different spot), but you run into the issue of getting it to speak/cooperate/communicate with the new E92, which I don't think anyone has tried. The only video I've seen of anything working in this application was on a 1320Videos video with a Nova where they were using an LT4 long block (built motor to 388 C.I.) and twin turbos, and it had a powerglide in it. Don't know if it was a manual valve body or computer-controlled, but what I do know is that they used the factory computer to run the DI injection system and piggybacked the rest to an MS3 Pro. After dealing with some issues, they were able to make that thing boogy to a 9 second pass at 148mph. So, these engines have potential to haul ass, but we just haven't figured out how to crack the system. So, at this point, I'll just leave what I've discussed here and see where the thread goes from here, and I'm hoping people chime in and vendors are watching/listening. Even though the demand isn't hot for it right now, there's going to be a surge for good transmissions when people can buy these trucks/cars/motors/transmissions for pennies on the dollar. Unfortunately, I feel like we'll have to wait that long in order to see results, but oh well. Just to give you guys an example: In the next year or two (2019 or 2020), I'd like to go turbo with my truck. (Doing all the supporting mods before going there minus built bottom end until I see where I can get with stock bottom end before sending a rod through the block or oil pan) Ideally, it'd be best to have a transbrake in that application with 2-step, but can't do it on the new transmissions. So, 4L80 seems to be the option, but I can't do that either because no one supports adapters or harnesses to make them work with the new motors/ECUs. That's the boat I'm in. I like to research everything before I go whole hog into something. Risk assessment, I guess.
  19. Seen alot of posts like this but none that quite answer my question. I have a 2018 Sierra 1500 Denali with the 6.2. I am thinking about installing an electric exhaust cut out before the muffler. (For arguments sake let's say my best friend is the warranty manager at my local dealership so I am not concerned about warranty mumbo) What I'd like to know is if I am going to run into any check engine light or any other messages popping up that she will pissed at me about it. I noticed alot of people with '14s and '15s not having issues with them but I feel like this 2018 has so many sensors and is so touchy that I'm hoping to hear from someone on here with the same year that has done it or knows of someone who has? I dont have any oxygen sensors back that far but is this engine computer smart enough to realize there is no backpressure from the muffler or something like that. I may just be being paranoid but really dont want to have to look at an idiot light over it. Wouldn't be worth it..or would it Any logical input would be very appreciated!
  20. I recently bought a new 2018 Silverado 1500 Crew Cab LTZ with the 6.2 liter & 8 speed transmission. I bought the truck in Idaho (great deal) and drove it home to California. Since then I've only put a few hundred more miles on it, 1181 total miles to be precise. Yesterday the tranny started shifting really hard & clunking on downshifts. Today, when I put the truck into drive it barely moves! Obviously, the transmission is slipping as the engine revs but the truck doesn't really move much! Any info on if the truck can still be returned at this point or am I stuck rebuilding a brand new tranny? Doesn't seem right to have to go through this so soon! I hope GM will either let me return the truck completely or give me a brand new transmission. Any insight on what may happen would be appreciated! Thanks in advance!
  21. 2018 LTZ wheels

    I have a set of chevy LTZ wheels were on the truck about 2 or 3 days before being replaced. No TPMS. I'd say wheels have 20 miles on them. Perfect condition. 6 by 5.5 18 x 8.5 Located in west Arizona
  22. I've read enough about these valves to want to clamp it in the full open position until I can delete it entirely when I get a cat-back exhaust. But, how in the hell do you clamp off the round ones on the 2018 trucks? Here's what mine looks like, and a simple hose clamp managed to slip off after only two days.
  23. I've a 2018 GMC Acadia. It is a FWD 3.6L/6T70. Recently, I've not been able to move the shift lever to Low ranges. It was intermittent at first & today I was not able to shift it into low range at all. Wondering: if anyone else has experienced this?, Fix?, Bulletin? This is a potential safety issue. Thanx Bob
  24. Hoping someone can help me find the part number to the rear driver side manual door locking pin/knob for a 2018 Silverado 1500? My buddy and I took apart my door to install subs in my truck and while he was trying to put the door panel back on he broke the lock pin/knob. i been trying to find one online with no luck. Now I’m hoping that if I at least get the part number or a diagram of inside the door somthing will pop up on the internet? i will attach some pictures below of what I need. Thanks!
  25. I have a 2018 Chevy Silverado 1500 LT Z71 with 8000 miles. No modifications. Great truck, almost no issues but... I have owned this truck for 7 months now, and for the second time in the last couple months, it has left me stranded for around an hour each time. When i start the truck i receive the "Power steering reduced, drive with care" message. But unlike others i have read about, i can not turn the steering wheel with all of my strength. Also the truck will drive forward in this state, but not reverse, nor will the back up camera come on. And the AC and blower wont turn on unless i spin the dial a few times. Each time i have opened the hood and pulled out and plugged back in all the (really hot!) fuses and after about an hour the issue goes away and i can drive again. Why would the fuses be so hot just sitting in the parking lot, maybe they always are. who knows. I took it to the dealership and they are trying to recreate this issue, but since its only happened twice in 7 months that's not likely. So they told me next time this happens to have it towed. How inconvenient is that though! Cant they run diagnostics or troubleshoot with the many symptoms the truck has in this error state? I was hoping someone here has an idea i can tell this dealership to try since they don't have ideas of their own. Thanks!
