What did you do to your AT4 today?

Remi: yellow fog lights look awesome. They definitely make a difference. Had a 1990 Chev Step Side Z71 package back in the day...lol and I ran a Warn push bar on the front with Hella yellow fog lights. Driving up to Northern Ontario for snowmobile trips in heavy snow storms those yellow lights would really help out day or night. Good choice ! Mods look great (y)
Thanks Joe, I appreciate it. They work great!
 

Installed the LASFIT LED license plate lights and damn was it a beating. Little easier if you remove the bolts holding the rear bumper and brace together and bend the brace a bit. I don't remember it being as difficult on my '21 AT4

Just ordered wiring mods from Boost Auto for Auto Fog lights (fogs on w/ parking lights) and Dual Function Cargo light (cargo light on in reverse). Had the Auto Fogs mod on my 2021 and install was stupid simple. Took me longer to figure out which pins on the connector were right than it did to actually install the jumper wire.
 

Hi-new to forum. I have 24 AT4. Question for folks with Ready Lift 2.0 SST. Only has up to 2023 on website. Does the 23 option fit with no problems on 24?
 

Just finished installing Readylift 2.0 SST, Fox 2.0 (front), and Bilstein 5160’s (rear). Had a terrible time getting the stock ball joints out due to the taper and not wanting to crack the aluminum casting w/ metal hammer (went with metal hammer anyway and everything came right out). If you’re methodical with your work, will probably take 8 hours assuming disassembly being a b$tch but my truck is also 3 years old too. I tried installing without the preload spring spacer first but you lose 1” of height without it. If installing Fox 2.0’s - you’ll need to grind down the supplied plastic spring seat to fit the ready lift preloaded spacer, you can kind of see it in the picture but not super clear (readylift 2.0 SST is meant for Rancho shocks but if you’re savvy with a grinder, you’ll be good). Pictures shown include both preloaded spring spacer and strut spacer on the top hat. Needed alignment big time, highly recommend. Tires - went with 285/70r18 (33.7 x 11.2) on -12mm offset with very minor rubbing that should be fixed with some strategically placed zip-ties on the wheel well but if I went any bigger I could see a lot of rubbing. Overall extremely happy despite a little rougher ride as expected w/ the preloaded spring spacer, gained 3” height and rear sits 0.75” higher than front. Hopefully this helps anyone else looking to do something similar.
 

Is your AT4 a 2023 or 24? Asking I’m going to buy same lift. I have a 24 AT4 1500. Ready lift hasn’t confirmed this lift will fit on 24 yet. Say they are still a few months out on this. Tempted to buy it anyway. I really doubt there is any difference at all.
 

Installed Boost Auto mods for cargo lamp and rear courtesy lamp on in reverse and fogs on w/ high beams. Now I can see at night when backing up!

I checked the part numbers of the UCA and they are the same for 2023 and 2024 so the lift should fit.
 

Nice design. Would you be willing to share the stl?

I picked up my 2023 6.2 about a month ago. First picture is the way I drove it home. Things I have done so far:

New Tires- Nitto Recon Grappler 285/65/20
Installed Ready Lift 1.75” Leveling kit with the new UCA’s
Added a Retrax Pro XR bed cover
Swapped chrome badging to black
Tinted front two windows to match rear
Dealer installed illuminated GMC Emblem
What did you use to paint the rims?
Looks great!
 

Not any sort of mod or anything....but I discovered the speed limiter in my '24 AT4X 6.2L on the way in to work this morning. 98 mph. Surprisingly less than my '21 AT4 6.2L which was limimted to 112 mph. I gotta say for a nearly $85k truck I'm somewhat disappointed. I understand why it's limited with having M/T Badyear tires and front & rear lockers and all but still.....98 mph? Wow.....
 

Lease is up next month on my ‘21 AT4 and still up in the air about keeping it and making some mods or getting the new model. I’d like a new truck, but I don’t want to give up all the options I have now and I’m not completely sold on the look of the new model(although the headlights look insane).
In a perfect world my truck would look like this and was wondering if any of these custom parts are available or if this is just a fairytale.
