I replaced my pass side light bulb about 5 months ago with the same type of halogen bulbs that they come with out of the factory and one day i realized that the same side as before went out. Before that one went out i had a set of after market LED lights. these to be exact https://www.amazon.ca/Lumen-9012HLC-G7-LED-Performance-Bulbs/dp/B01N5Q0TMA i ran those LED's on my truck and they looked great! everything was plug and play they lasted for about 4 months when my pass side bulb gave out on those too. when i took out the bulb to inspect it one of the LED diodes was blown out. I wasn't too surprised by that because sometimes after market parts can be a bit cheaper quality. But when my OEM halogen bulbs went out. thats 3 sets of bulbs in less than 2 years. I am just wondering. Is this bad luck?? Have any of you had this issue before?? if you did what was causing it?? any troubleshooting tips?? I really dont want to keep buying light bulbs every 5 months even the halogen bulbs are a little expensive

I know there are a few different forums on this topic, but they seem to have gone dead. The steering in my truck clicks and clunks especially at low speeds, and the truck wanders on the highway. I am constantly holding the wheel to the left or right to go straight. I have had the intermediate shaft replaced per the service bulletin. After it was replaced some of the noises were reduced, but not eliminated and the truck will still not track straight especially at highway speeds. It almost feels like a bad tie rod end or ball joint, but the dealership said everything is nice and tight, and I checked just for my sanity. I also added a steering stabilizer in hopes this would help. Is anyone else having these issues, and have you been able to get them fixed? 2020 Silverado LTZ with 6.6 DuPIT5809.pdframax

So ive been seeing the conversion on 08-13 Sierras , and very popular on Silverados even the 14-16 conversions. On feb 1 some jack ass cut me off and hit my front bumper and fender , lucky for him i was already looking into doing a 2018 denali headlight conversion with the gen5 wiring harness and 2015 HD front bumper with 2500 all terrain grille To keep the theme going. As I researched could not find anything on the 2014-2018 sierras being converted to HD , all the guys i saw on IG with them had shops or buddys do them. Some guys welded either the 1500 or 2500 brackets lower ,enlogated the holes lower, redrilled , some had no gap -some liked oem gap between the grille/fenders. I did find two guys I kept intouch with they were a lot of help. One sent me pictures on how to re-drill the stock bumper brackets lower and cut some parts off it to clear the bumper , the other told me 1/2 above the existing holes . I took it upon myself to source a complete front bumper from ebay with everything $750 with shipping all i have to do is paint it , found a all terrain grille on ebay for $300 , had to buy the 2500 bumper guides and 2500 bumper fillers no luck on hood yet.while the parts arrived i bought the 2018 denali lights from fankie on here and the harness from gen5 easy bolt on by the way. When all the parts arrived i grabbed my grinder and drill . To start i took the 15torque head screws and 7mm from the sides of the wheel wells , took the 12 plastic clips from the upper cover , removed the 4 top 10mm bolts ,pulled off the bumper filler pieces between the grille and bumper , exposing the 10mm 4 bottom grille bolts , then removed the grille. Gaining access to the 4 18mm bolts that hold the bumper on the brackets, i loosened but did not remove till i went under the front bumper and removed the 2 outter 15mm bolts that hold the bottom of the bumper , i loosened the inner 15mm bolts but did not remove , once that was done i removed all 18mm bolts holding the bumper and took it off . Once off the stock 1500 bumper brackets have 3 15mm bolts in a triangle pattern, i removed all 6 and removed the tow hooks , the tow hooks will be eliminated from this . Once i had the brackets off i measured 1/2 inch above each hole . Now this is important if you want oem gap like myself i drilled a hole slightly bigger than the bolt going threw at the center of that 1/2 mark . If you dont want gap id suggest drilling under the 1/2 mark and possibly enlongating that hole down wards for adjustment. By drilling the hole a 1/2 inch higher it drops the bracket to clear the 2500 grille . In addition to redrilling the bracket you have to cut an L shape on top right next to the top bolt that the bracket has , i actually cut the bottom of the bracket and eliminated the bottom slot for the second 18mm hole because i was having issues lining up , ended up not being the problem , i found that out of the 6 15mm bracket bolts you only use 4 the top and inside 15mm the outter 15mm that completes the triangle actually hits the hd front bumper and it sags in the back ,so removing levels the bumper flush , i tried grinding the head down and still no luck removing was the fix. With the bumper off , you want to remove the 1500 bumper guides 3(7mm) bolts rachet wrench works best and socket aswell , install the 2500 bumper guides with same bolts same place these support and clip on to the new 2500 bumper filler pieces under headlights which youll have to buy . They clip and slide right on , the two bottom outter 10mm bolts that held the old grille will hold these in place and the other two 10mm in the middle from the old grille will be eliminated. See pictures.To finish securing the bumper filler and guides you have to screw the 7mm and 15 torque screws by fender trim , you will either have to buy the 2500 or 18 fender trim pieces or just trim yours roughly enough to bolt on the remark to trim perfectly and level like i did cant even tell .So Once the guides and fillers are installed grab the redrilled bumper bracket to your liking in gap, make sure its clearanced with the L shape you can rebolt bolt to frame leaving the outter 15mm off at that point you can lay the new bumper on the brackets rebolt the top 18mm bolts the bottoms wont line up -i eliminated by grinding off ,see pic -you can reconnect the lower 15mm outter brace and tighten , youll find out that it bolts right up and if you drilled at 1/2 center like me you keep that stock oem gap maybe a bit tighter gap actually but it looks good , you can then install the grille by pushing the clips in and only bolting on the the top 4 10mm bolts once done youll find that the gap is nearly perfect if you drilled at center of the 1/2 mark , some drill under the 1/2 mark to get less gap and some enlongate the hole lower towards the original hole to adjust and have no gap , but i see that as rubbing issues with paint. sorry for rambling on on the install , i will try to post all my pictures size will be limited and ill go back to proof read fix anything that i missed. Let me know waht you guys think or if you need help

So I bought a 2019 GMC Sierra elevation from a dealer in town here. Was told is has the 2” factory installed suspension lift and nothing more. But after a week or so I decided to look into a leveling kit, watched a couple vids online and noticed how some kits can go under the damper? out of curiosity I wanted to squeeze my head behind my tire and take a look only to notice what looked like an already installed 2” level. can someone help me identify if that is a leveling kit installed in the picture I attached? Also if so, why isn’t the truck level? Is the rear block too big?

Looking to upgrade the stock wheels and tires on my '19 Sierra 1500 (extended cab, 4WD). I can get away with just blocks if I go with 33" tires, but need a lift if I go to the 35" tires. I don't want rubbing...but also don't want to get too aggressive on the lift. It is suggested that I go with a 6" lift. I don't do any offloading and I'm not trying to "act" like I do. I just love the look of the bigger whee/tire on this truck. Looking for suggestions from those who went with the 33" tire vs the 35" tire and what size lift you used (if you went with the 35" tire). Just throwing this out there so I can get some feedback from those who have already "figured it out." Thanks all!

Has anyone added reverse lights on 2019-2021 sierra? I need ideas!!! I was thinking about rigid ignite flush mount. Show me what you did!!! thanks!

Looking to get a decent set of chains/other traction device for my Silverado. I have P265/65/R18 size tires and the owners manual says to not use chains with this size tire as there isn't enough clearance and you risk damage to the vehicle. It also says "Use another type of traction device only if its manufacturer recommends it for use on the vehicle and tire size combination" My question is... has anybody out there found a manufacturer/model of chains where the manufacturer recommends it for this tire size on a 1500?

Has anyone ever tried changing the aluminum line to rubber hose crimps for the transmission and oil cooler lines out for AN fittings on and 07-13 Sierra 5.3L? I have a 2013 Sierra and the cold here in Canada isn’t kind to these crimps as I believe the rubber and aluminum have different shrink rates because of difference in material causing them to leak. Replacing them will not solve the problem as the will just do the same thing every year. So what I want to know is if anyone has successfully done this and what fittings did you use?

Hey guys, Cold weather has made me take out my winter front for my grille for the first time. It has a convenient hole for the camera but looks awful as 4 inches of the grill on either side are still showing. Is everyone else’s like this or did the dealership give me the wrong one?

Has anyone encountered issue with their AT4 where the battery keeps dying after extended period in the garage?? First time it happened I thought maybe I left my dash cam plugged in and that drained the battery. Since then I don’t leave the cam on when I leave the truck but it still happens on my weeks off and I don’t drive the truck. By the next week I have to boost the battery to get it to start again. It only happens if it’s not driven for at least 5 days. any help will be appreciated. thank you

Has anyone ordered an aftermarket Denali grill online? My truck is a 16 SLT, but I think the addition of a Denali grill would make it look even better. I see all kinds of “Denali style” grills online and don’t want to order one blind just to find out it’s junk. Any reviews are appreciated!

Hello, I’ve got a 2008 GMC Sierra SLT with z71 package. I’ve had it stock until this year (2020). Recently put a level it in and had the truck aligned and it ran great. Went to put new tires and rims which are 33x12.5 Toyo open country AT2 extremes on 18x9 fuel assault wheels. The truck obviously had a decrease in power and mpg but recently it has gotten significantly worse. On HWY I can get 18-16 but recently in the city I am getting 11mpg!!! I live in a city with a lot of hills and windy driving so I can attribute that to some of it but it seems low. I’ve looked around and some guys suggest checking air sensors and tune ups, but I am wondering at what point is it a bigger issue? Or is it the reality of a lifted truck with heavy tires? any suggestions are welcome, it has not been 11mpg for long just the last month. Thanks

So i have a 2021 Silverado Custom and Ive been wanting to upgrade my clusters and Steering wheel. I see alot of people saying it the Audio controls dont work because of the radio but from what I've seen there are LT trims that also have IOR radios(like the customs and w/t) and Steering wheel controls. With that being said, then the wiring is possible for steering wheel audio controls to work, no? and if the clusters are swapped as well, wouldnt the steering wheel be able to connect to the new clusters?

Hello, Cruise control stopped working (neither normal nor adaptive). When I press the dial to "set" the cruise speed nothing happens, also I read I should be able to change between normal and adaptive cruise by pressing the "cancel cruise" button, but when I do nothing happens. Truck comes from a GM employee who had diagnosed it as the steering wheel being the culprit (in case the switch was defective); he gave me a new steering wheel with the truck which I swapped but it did not work. I guess the easy route would be to take to the dealership for them to diagnose, but since that will take longer and usually several visits: What else should I try? Any specific fuse or something else I should check? thanks! ps. gratuitous pic of a dirty Sierra for your time

Found out I need to replace my fuel system control module In my 2009 GMC Sierra 1500 , I bought the truck which has a after market turbo charger in it but if there is a tune on the truck and the FSCM needs to be programmed to the vin number will it still work properly if I install a new one like that ? Or will I need to get the new fuel module programmed differently ? I also am under the idea that it may be the reason the last one went anyway

After upgrading my base cluster and steering wheel. Is it possible to control the cluster from the new steering wheel? How is this wired? Ive seen videos for models up 2014-2018. However, nothing on new gen trucks (2019-2020).

New to the forum and I’m looking for some help. I have a 2014 Sierra that I’m taking to get a 4” readylift and 35/12.5/22 trail grapplers installed. Im keeping my stock 22” flakes. The lift company says I will need spacers for stock wheels. But Idk what size should I run. I do not want to trim my studs!!

I jumo started a car with my 2014 GMC Sierra. While jumping it I noticed that I couldnt press the accelerator to give it more juice. I unhooked the cables and realized that the powersteering and the accelerator would not work at all. I turned my truck off and then back on ,but the problems were still there. I now cannot get my truck to even attempt to turn over, but the battery and fuses have been checked and are good. Any ideas on what the problem could be?

I own a 2019 next gen sierra (elevation) and I'd like to install the extended view tow mirrors (part # 84776098). My truck is equipped with DLF and not UKC as specified in the part description. GM says these mirrors will not work on my truck …. GM enthusiasts. Is this true? I feel like it's bullshit and the harnesses are plug and play? If they're not plug and play, is there an alternate harness? It can't be possible that this 1/2yr model can't be equipped with tow mirrors? Help please …..

Has anybody come out with a power programmer for a new body style Sierra Denali with the 6.2 ltr. 10 speed transmission? Jim
