Can you put a leveling kit on an AT4?

  • #1

Folks who have leveled their trucks... RC 2" or ReadyLift 2"? Were UCA angles bad and needed replaced or were you able to keep the stock ones on. I see that RC's does not come with them unless you order them separate and there's a pretty significant difference in price between both kits. The rake is just annoying to me at this point. Would love to hear some feedback. Happy Friday!

I’m going with the Bilstein 5100 Height Adjustable shocks. Will eliminate rake and get rid of the awful Rancho’s. Keeps current setup with UCA’s. I think I will get about an 1” to 1 3/4” height increase on the front with them. Just another option to the 2” leveling kits.

Interesting. Have never even heard of them, do you have a link? I just looked at yours though and it does sit nice!

Yes I will have it professionally installed whatever I choose. Just need to make up my mind which one to go with

I went with the cheaper RC 2" and have had no problems.

Are you running stock wheels and tires still? I've been told the RC 2" is hard on UCA angles if you're going to go to a bigger tire and have even seen some nightmare pics of blown out wheels. Do you have a pic of your truck?

I went with a 35" tire and 17" rims. I attached a photo. So far so good.

yes I've heard this too. They told me that you need to put new UCA when you put leveling kit on an AT4. Had several shops tell me this.

I believe the RC UCA's are around $500. Everything I've heard says raising these factory lifted AT4's anything over 3.5 inches in total you're asking for troubles if you don't replace the control arms. I'm not sure why RC didn't just include them in the kit like the ReadyLift 1.75 leveling kit does. I am shocked you haven't had any problems with your 35's. How long have you been running them?
I guess in the same manner I'd be interested to hear from people if they prefer the RL 1.75 level or the RC "true" 2" level. I haven't leveled mine yet because I can't make my mind up.

Looks good. I have questions.... 35x12.50? 0 offset wheels? Any rub?

  • #14

It actually didn't "level' the truck as the front still sits 1/2" lower. The lift and tires have been on for a few months now with no issue. It also has kept alignment. I am just going to run with it until I see trouble.

Yes...35" X 12.50, 0 offset wheels. There was rub. I had to do some trimming.

Does the AT4 have 2 inch lift?

AT4 capability features include: Factory-installed 2" suspension lift. 2-speed AutoTrac transfer case, automatic locking rear differential and skid plates.

Does the AT4 have a lift kit?

The AT4/Trail Boss are factory equipped with a 2" front lift. This front lift includes a longer front shock/strut assembly.

Can you fit 35s on AT4?

Do 35″ Tires fit on a GMC AT4? Yes but not without some modifications and very specific offsets. Running 35s on the GMC AT4 requires a very specific wheel offset in addition to the below trimming. To be on the safe side you want to maintain a 8.5″ max width and at minimum a +18 offset (higher will be better).
