  3. 2016-2018 GMC Sierra Elevation grille that's been professionally painted black. This is a brand new OEM grille. I bought it from a member on here, but also decided to go with a different grille. The grille itself looks fantastic, the only reason for going with another grille is I have seen another truck identical to mine with the same grille, and I want to have something different... $500 shipped. Only asking what I paid for it. Current location: 54016 Thanks!
  4. GM has available now factory camper mirrors! Time for a nice run down on them and what is involved. What they are: Factory tow mirrors. https://accessories.chevrolet.com/product/extended-view-tow-mirrors-in-black-84731241?year=2020&make=Chevrolet&model=Silverado%201500&categoryId=98023 Price? Part #? 84731241 is the #, MSRP for the mirror package is $730. What do they feature? Includes lower convex spotter glass, as well as cargo lamps, clearance lamps and integrated turn signal indicator. Manual extend and manual fold. The good: -GM has factory tow mirrors available as an accessory for trucks that don't have them! The bad: - 2020+up ONLY at the moment. They do NOT list them for 2019. - They DO REQUIRE HARNESS SWAPS. Both front doors require new door harnesses. - If you have the front spotter lights in the mirrors or have blind spot alert, THESE WILL NOT WORK! - BCM calibration required for ALL models to make all lighting function. If you have the dealer do it, its about 3.6 hours. Harness numbers will be listed below: 2020-2021 Crew and Double Cab with KEYED ignition and DLF mirror: 84622369 and 84622370 2020-2021 Regular Cab with KEYED ignition and DLF mirror: 84622376 and 84622380 2020-2021 Crew and Double Cab with PUSH BUTTON ignition and DLF mirror: 84622371 and 84622372
  5. I have an aftermarket stereo in my 2006 GMC Sierra 2500HD with the Bose sound system. Currently, i only have one speaker working, the other 3 have no sound coming from them. Any idea what could cause this? or a work around for the Bose system. Im tired of listening to my music through one speaker.
  6. Hi all. Looking for a single down-fire sub-woofer enclosure for a 2019 Sierra Crew Cab, new body style. Any tips on where to find this? Thanks! B
  7. Not to beat a dead horse but I can only seem to find info on 2014-2016.... My Truck: 2017 Sierra CC SLT 5.3 with the stock 20in (20x9) rims & Bilstein 5100s at 1.25" I want to get new tires (nitto ridge grapplers or toyos etc) and I would like to move up to a 285/55r20 if possible. From what I've read I know the UCAs changed for 2017 making guys experience rubbing on the UCAs with 33s on levels. Was wondering if anyone had done a 285/55 on stock rims with stock height or Bilsteins and did they rub, or rub all the time/just full lock? TIA -Ed
  8. It's never too early to start talking about the process of shopping around for a dealer, pricing, the ordering process, deposits, and production delivery times. Although we're still months away from orders being accepted, this thread is meant to be a place where everyone can check in and share their experiences as they go through the process. I'm also going to document as many important dates in this initial post as I can. I'll attempt to keep everyone up to date on start of production, any ordering limitations, and when the ordering system will go live.

  9. John Goreham Contributing Writer, GM-Trucks.com 9-11-2019 General Motors has announced that NHTSA is mandating a safety recall for the following vehicles: 2014-2018 Chevrolet Silverado and GMC Sierra Pickups (1500 / 2500 / 3500) 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles 2015-2017 Cadillac Escalade NHTSA reports that the amount of vacuum created by the vacuum pump may decrease over time. The group says that as the vacuum level drops, the brake assist decreases, and that this increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. This new recall covers 3.4 million vehicles. The Problem: The brake pump uses engine oil to lubricate itself. If the pump becomes clogged with engine oil sludge the units ability to create vaccum is diminished over time. As a result, braking force and ability also drops. The issue is usually accompanied by a "Service Brake Assist" warning message in the dash. The Fix: GM will reprogram the computer that controls the secondary brake assist pump. The secondary pump will now activate at lower speeds and different situations quicker to compensate for any lost output from the main pump. Since the pumps are not failing, GM has decided not to replace them. GM's number for this recall is N192268490. In compliance with federal law, GM will notify owners, typically by snail mail. GM says that its dealers will reprogram the Electronic Brake Control Module. However, GM has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. If you own one of these vehicles and wish to check to see if your vehicle is included (or not) you can do so at this link immediately. As with every safety recall, customers will not be charged by GM for the needed repairs or modifications. NHTSA's public information on this issue indicates that many accidents have been reported to NHTSA including some with injuries. This recall is the result of a NHTSA investigation that lasted nearly a year. In its investigation report, NHTSA noted the following details about the problem:
  10. Has anybody come out with a power programmer for a new body style Sierra Denali with the 6.2 ltr. 10 speed transmission? Jim
  11. Just got 2019 Sierra Elevation. Looking at options to install a 20 or 22” LED light bar. Had one in my bumper opening on my 2012 2500 HD and found it indispensable for night time driving in the backwoods. Has anyone installed one yet? Share your pictures of your setup if you have. Thanks!
  12. I am in process of blacking out my 2014 Sierra Crew Cab. I have the chrome window trim at the moment. I see GM sells the Chrome for $450 and the Black plastic for $185. I am hoping I can find someone that wants to make a trade plus some cash. Or... you have black takes offs and already have chrome installed I'll but them direct and sell my chrome take offs separately.

  17. GM recalls 160,000 pickup trucks in Canada for fire risks, nothing announced in US yet As of right now there is a recall for all GM 1500's years 2014-2018 that have both a rear window defogger and a power sliding rear window. https://www.cnet.com/roadshow/news/gm-recall-pickup-trucks-canada-fire-risks/ That recall has not been expanded to the US. I Just got off the phone with GM and filed a request to have the recall expanded to the US. I would encourage everyone who this applies to in this forum to do the same. It takes about 5-10 min but could save us all a lot of hassle later. HAVE YOUR VIN READY Call GM @1 (866) 522-9559 Reference this recall number: Manufacturer Recall Number N192220470 (This is the recall number from GM in Canada) (reference: https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/detail.aspx?lang=eng&mk=0&md=0&fy=0&ty=9999&ft=&ls=0&sy=0&rn=2019325&cf=SearchResult&pg=50) They will tell you that the recall only applies in Canada and not to your VIN. Express to them that the recall needs to be expanded to the US since our vehicles are also affected. Please post here if you have called GM (just so we can keep track) Please also post if you have experienced this issue (smoke, glass breakage, etc) Affected components: electrical – rear window defroster on trucks equipped with the power sliding rear window. Affected vehicles: 2014-2018 Chevrolet Silverado 1500 2015-2019 Chevrolet Silverado HD 2014-2018 Chevrolet Silverado LD 2014-2018 GMC Sierra 1500 2015-2019 GMC Sierra HD 2014-2018 GMC Sierra LD It may be a good idea to sticky this topic.
  18. Here is a little extra information I found on from GM TechLink with tips and details regarding the lift points on the new T1 GM trucks. Newdude posted something similar in the frame issues topic a while back. I just thought I would add a little extra to that information. Lift Points TIP: Prior to servicing the vehicle using a lift hoist, the vehicle power assist steps must be disabled to prevent accidental activation. Use lift pads/spacers to provide proper clearance between the lift hoist arms and the vehicle’s fixed or power assist steps. After servicing the vehicle, be sure to enable the power assist steps. For lifting the vehicle, various lift points are recommended. (Fig. 13) The lift points are: Circular jack pad Widest point of the frame rail; requires adapter that is wider than the frame rail when using a hoist. Contact your hoist manufacturer for the appropriate adapter. Rear frame contact points Rear axle contact points Differential contact points Fig. 13 For the front locations, the two approved lifting points are the circular jack pad (Fig. 14) and the widest point of the frame rail, which requires an adapter from the hoist manufacturer. (Fig. 15) Fig. 14 Fig. 15 The hoist pads must not contact the rocker panels, the floor pan or, at the front pad location, the front fenders. Lift pad adapters for Challenger and Rotary lifts are available through GM Dealer Equipment. When lifting at the differential (#5) with a floor jack, avoid point loading the center section of the axle, which is aluminum on most rear axles. Use a floor jack with a rubber pad or wood block to prevent damage.
  19. Zane Merva Executive Editor, GM-Trucks.com 3/5/2018 With the debut of GMC's all new and very fancy MultiPro Tailgate last week in Detroit questions have been floated regarding various aspects of the design and how available the tailgate will truly be. So, we reached out to GMC directly and have some answers for you. Here we are in no particular order: Will the MultiPro be available on any trim level other than SLT and Denali? YES. Although only the SLT and Denali trim levels were mentioned last week, we can confirm the MultiPro tailgate will be available on the SLE trim level as well. Can I open the MultiPro with the keyfob? YES. Just the tailgate as a whole, however. There's no option to open the inner section unless you do it with the button on the gate. Will the MultiPro prevent itself from opening into mounted ball hitch? NO. This is the biggest issue we can see with the MultiPro going forward. The inner gate is fully susceptible to damage from a mounted trailer hitch. GMC does mention that a warning sticker will be present to remind owners not to do just this. Owners will have to remember going forward that if they leave a ball hitch mounted, the MultiPro WILL HIT IT. Will GMC offer a manual (cheaper) version of the MultiPro later on? UNDETERMINED. GMC wouldn't answer our questions about a cheaper, manual version of the MultiPro in the future. We think it would be a great idea and GMC punting the question means the option is in play for the future. Will Chevrolet ever get the MultiPro? LIKELY. Although no-one from Chevy is talking, we expect the Silverado to get the MultiPro (or a Chevy-named version) at some point in the near future, perhaps in model year two (2020)
  20. So i have a black 2018 sierra 1500 wt with the stock chrome front bumper amd im looking to change it out for a body colour matched bumper. Does anyone know of the bumper off a same year sierra elevation would fit? Or even better does anyone have a part number that would be a direct replacement? Thanks
  21. I really like the bold/big muscular grille on the Sierra. It stands out a lot on Denali with that massive chrome surround. However i don't like chrome. I think this contrast is somehow lost on the AT4 because of the body-colored grille surround. I'm in the process of trying to wrap or paint the grille surround on my AT4 to black but i want to keep my factory red grille surround in-case i ever decide to go back to the stock look. I was looking to buy just the grille surround, wrap or paint it and install. However, it seems the grille is available as one-piece only and you can't get just the surround alone. The whole grille is fairly expensive, over $700. The alternative for me is to buy the accessories grille ($450) in black and just install. I think the accessories grille is the Elevation trim grille and because of my vanity , i don't want to install a Elevation grille on an AT4. I don't believe i can swap the insides. Anyone done this? Grille surround indicated in yellow. Accessories grille in black.
  22. See a lot of questions asked about this and not a lot of set info on the upgrade. Hope this helps even anyone trying to set it up. **READ ALL INSTRUCTIONS AND WATCH ALL VIDEOS PRIOR TO ATTEMPTING PURCHASING OR INSTALLATION** Apple CarPlay / Android Auto functionality is not supported in any 2014-2015 (Many 2016) Silverado/Sierra’s. This is due to neither application being available from Google or Apple when these vehicles being built, therefore not an available option during these model years. The following instructions are designed to simplify the process as much as possible. Three things are required for this upgrade (ONE) Radio Module, (ONE) HMI Module, and (ONE) USB Hub 2016+. Search around for the modules, they are available for purchase from many different locations. EBay, totaled vehicles, junkyards, or other various websites to find them. AGAIN, if the part numbers are not listed below DO NOT purchase them. It is highly encouraged to not try and cut corners with purchasing part numbers of modules not listed as they cannot be flashed to work properly. **DISCONNECT THE BATTERY PRIOR TO INSTALLING FRESHLY UPDATED MODULES** TOOLS REQUIRED: Trim Removal tool 10 mm Socket 7 mm Socket PARTS REQUIRED USB HUB P/N 13519224 (BLACK) P/N 13509943 (WHITE) HMI Module USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITH NAVIGATION. ONLY REQUIRED TO PURCHASE ONE P/N. 84006103 84048396 84096817 84156701 81431943 84296482 USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITHOUT NAVIGATION. ONLY REQUIRED TO PURCHASE ONE P/N. 84096815 84156699 84131941 84296480 84004948 84048398 84131941 84296480 RADIO MODULE USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITH BOSE. ONLY REQUIRED TO PURCHASE ONE P/N. 84062073 84293226 13506371 23402903 USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITHOUT BOSE. ONLY REQUIRED TO PURCHASE ONE P/N. 13506387 23402909 84062056 84293243 Once acquiring the parts you can now send them to be flashed. These modules will be flashed to your VIN and will then be plug and play. Copy the link and follow the prompts. http://www.whiteautoandmedia.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=98&category_id=44&option=com_virtuemart&Itemid=54 If you have followed all the directions up and to this point, select yes for hardware match. You can chose if you would like the maps updated on your NAV if you so choose. You will be emailed your order number from WAMS, this is EXTREMELY IMPORTANT. You will be required to ship your parts either FedEx or UPS, they will not accept packages from USPS. You will need to write your order number on the box to ensure your order is properly handled. Turn around is approximately one week from shipment to return. ONLY ship your (ONE) Radio Module and (ONE) HMI Module. Maintain your USB Hub. Once you have received your parts from WAMS you can begin installation. Disconnect your battery prior to installation. To install the radio module watch https://www.youtube.com/watch?v=I2MYuuyqLrs. For the purpose of this install start the video at 1:00. Stop the video at 2:04, the radio module is visible with a green connector on the far left. Simply begin disconnecting all of the connectors plugged into the module, once all are removed you can slide the module out of the dash. It is retained only by the tension of the cables plugged into it. Replace with your new module, you can now continue the video and finish putting the dash back together. Stop the video at 4:10. To install the HMI Module watch https://www.youtube.com/watch?v=sFe2gwlOsD4. Stop the video at 2:00. The module being described behind the crossbar is what you are replacing. Remove all connectors, the module is retained with a plastic clip on top. Installing the module along with the glove box, is self explanatory. Take note of the plastic tabs on the sides of the USB Hub you are preparing to install. Those tabs can be depressed with a dental pick and gradually removed out of place. Once removed, disconnect the harness and reconnect. Installation is now complete. You can now reconnect your battery and start your vehicle. Initial start up might take a few seconds to initialize, and temperature defaulting to 32 degrees is normal. Android Auto and Apple CarPlay require hardwire connection, so to test functionality it needs to be connected to the newly installed USB hub. MVI Inc (https://www.gm-navigation.com/) offers kits and other customization options if the above is not something you feel comfortable acquiring on your own. Hope this helps, should be pretty cut and dry. There might be other methods, but this was the cheapest I discovered. If you have any questions don’t hesitate to ask.
  23. This has been an on-going research project of mine. I discovered when I inquired about having the Trail Boss (TB) factory lift kit (GM part# 84629787) added to my 2019 LT Z71, that I could not have the kit installed due to the secondary composite leaf springs on my truck. Upon further investigation, I found that ONLY the LT with 5.3L (and LT with 3.0 diesel and short box) had the composite leaf springs preventing the truck from having a TB lift added. On the GMC side, I found out the Sierra Denali also uses the same leaf springs with composite secondary as the LT 5.3L. My first impression was, “why the heck would GM do this?” Why wouldn’t the LTZ or High Country (HC) have the the composite leaf? Why would only the mid-level LT have it? The Sierra Denali has it and it’s a $60K+ truck. My LT averages around $45K. I might be a little upset as a LTZ or HC owner to find out my rear suspension is the same as on any Custom trim truck, or even, the base W/T model. I’ve doing a lot of reading on composite leaf springs and there are more advantages to them than disadvantages. Though they are dimensionally bigger (thicker) than the steel counterpart, they weight a lot less, last longer, and offer better damping properties than steel. GM has had a good track record using composite leaf springs. The same technology has been used on the corvette since 1997 with the introduction of the C5. Disadvantages are minimal, such as, they are more expensive to produce, can burn up in a fire, and in this case, can’t be further bent or altered out of original specification. This must be the reason GM won’t allow the lift to be added to vehicles with a composite leaf. I’m sure the leaf could take the additional stress, GM engineers just want to play it safer than sorry. So with this, the Silverado LT 5.3L (and LT 3.0 diesel with short bed) and the Sierra Denali are the only trucks to use the composite leaf. Though I’m disappointed I won’t be able to get the TB lift added, I’m now pretty stoked to find out my LT has more mechanical innovation put into the suspension and I didn’t have to spend $15K+ more for a Sierra Denali to get it. However with this, it seems that if someone is looking for a top-end truck, the Denali would be the better choice over the HC which lacks the particular composite leaf spring feature, if that mattered to the buyer. For reference, attached here are the GM compatibility charts for the Silverado and Sierra to see if you can add the TB lift kit. Also here is a link to the previous discussion about the TB lift kit where you can find more detail about installation and issues surrounding the composite leaf springs.
  24. **SOLD** 2016-2018 GMC Sierra Elevation grille that's been professionally painted black. This is a brand new OEM grille. I ordered it and decided to go with a different style grille, absolutely nothing wrong with this grille. Shipping to continental US is free, local pick-up near St Louis MO. Price is $500.
  25. The AT4 I purchased from the dealer, had everything but the performance package I wanted. So, the same day, I paid the extra cost to have it added. Once it was finished, I was excited about the purchase and the way it sounded. Now, weeks later, I'm starting to get picky about things and making sure everything is how I want it. After my cousin brought it to my attention that I should've made sure all the work was actually done, I looked up what the performance package consisted of. While I can see the performance exhaust is installed--I noticed that the tires on it are not the Goodyear Duratrac the GMC site lists; they're Bridgestone Dueler's. Next, the intake isn't the cone-type performance intake filter, its the flat fliter. Are these an alternate performance package option? Or did I get gipped? If so, would the dealer be willing to recognize these missing details, or would they think I just swapped the parts myself? I'd go down to the dealer right now myself, but the oil field life keeps me at work. Haha. It's a long read, but I'd appreciate the input. Thank you.
