Well I spoke too soon. Had the first led failure a couple weeks ago. Replaced it with one of the spares since the package had ten of them so wasn't too bad. Did notice that the 4 remaining leds were all missing their lenses though so probably only a matter of time before the others fail too. Going to look into other leds for the next go around. Sorry it took so long to see this. I used fuse #42.

Where did you purchase the marker lights from?

I installed my GM intake myself and drove it a week before getting it flashed at the dealer. No codes, messages or errors in my case.

They have a similar video for the GMC version. I'm actually more concerned about removing the grill and bumper without breaking retention tabs than I am about the headlight mod itself. I have tried to locate local installers just to get estimates for cost and only found 1 guy that would do it. All the rest "do not open headlights do to condensation/moisture concerns". It has me wondering how big a problem the condensation issue may be.

Following because I have the same exhaust on my 2019 AT4 and believe I hear the same rattle from time to time.

Hey Jim. Surprised to hear you needed so much lift to run 35's. I have 2019 AT4 with stock suspension and factory 20" rims running NRG 35x11.50 with no issues. I had very minor rub on the front of the drivers side well liner only when backing with wheels turned full lock right. This was easily eliminated by zip tying the liner bracket directly behind the bolt that there to one of the bumper mounts. I've had no rub since. I think the biggest issue is the wheel width and offset. I will say though, even with the stock suspension and 35's, my 5' wife still struggles to climb in the truck as well.. lol

Hi all, Lots of information here but haven't seen this upgrade. Anyone does this upgrade on a 2019-2020 GMC or even a similar update for a slightly earlier model year? Would like to hear your thoughts/observations and would you do it again? https://www.oraclelights.com/collections/gmc-sierra-products/products/2019-2020-gmc-sierra-oracle-colorshift-rgb-w-headlight-drl-upgrade?variant=31764823212129

I'm interested in the upgrade too. I saw the comment above in other post as well and have to say I'd like to understand that better. My 2019 has nav (so must have a gps antenna) and it has the ability to act as a hotspot in the vehicle, so presumably has a wife antenna. Wonder what antenna's missing?

I used to do them all myself but say a special at the dealer when getting my free oil change (only got 1) and jumped on it. Their normal price was $399 for 6 oil changes/tire rotations but they had a special for $299 so I jumped on it. There is no way I could come anywhere close to that price doing it myself.

I get about the same with my 6.2 AT4 35x11.50 NRG's, no lift. Has GM performance intake and Borla S-Type cat-back. I actually find the MPG to be quite temperature sensitive. My MPG seems to be at least 1 MPG lower when it's cold and that's in NC. Hate to think what the temps in farther north would do to MPG. Anyone else notice this?

Hey Chris - Did you ever figure this out? I'm looking to remove my for some mods too and am having the same problem finding information on how to remove them.

For what it's worth, these are the amber bolt lights I used from Amazon. They've been on my truck for about a year now with no failures. https://www.amazon.com/gp/product/B07CWPDZKJ/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

All good advice. In my mind, if it's dicey enough for chains, I would be in 4H, I wouldn't want to consider the vehicle moving in and out of 4WD.

How about the 2019 AT4? Will it work with that cluster?
