Those are the angles they don’t look too extreme to me but I’m not to sure would like a second opinion before I spend 300 dollars on uca’s and have to pull those struts back out

I just finished doing this to my 2020 Sierra x31

just remember the angles you see with the truck sitting still may not be the angles that are troublesome. It is when the front of the vehicle travels up llike when going over a bridge and the suspension travels up and down or bounces, and if the bounces are too violent the suspension will max the angles out as the front end of the truck travels up in the air, causing possibly a fracture in the ball joint

With that being said, I would like to point you in the direction of american trucks.com. That is where I found a great deal on a set of upper control arms. They have a lot of open box products sometimes at half the cost I was able to find a set of FAbtech upper control arms that normally were 300 and something dollars and I was able to get them taxes shipped and all for 136 so I jumped on it. I also upgraded the shocks all the way around with the Billstein 5100 adjustable shocks truck rides so much better with those shocks and also gives you the option to add up to 2 1/2 inches of lift to the front. So what I did was chose option for 2 1/2 inch lift, and I and paired that with the 2 inch upper strut spacer leveling kit that I had already put on the truck so now I am sitting at roughly 4 to 4 1/2 inches and the angles on my upper control arms look great everything aligned perfectly then added a 1 1/2 inch block in the back.
As far as the tire size I went with the 35x11. 50x 20 and have no rubbing but when I put the half inch spacers to push the tires out a bit I did get just a small amount of rub at 90-100 percent turn. I will
post pictures to give you an idea of my set up. Good luck on yours. Just wanted to share some helpful information.

Your truck looks great with that lift/level. I did almost the same thing on my 2022 AT4.

Welcome to the club.

Thanks for the compliment

Your truck setup looks tough. I like the wheel/tire choice too. What size tires you running?

Also how clean do the red calipers stay? Was thinking of doing the same thing as well as doing the red row hooks

The tires are Toyo Open Country A/T III 35X12.50R17LT mounted on

Icon Alloys Compression 17x8.5 +0mm wheels. Had to do quite a bit of trimming so I finally installed the Ready LIFT 1.75-Inch Front Leveling Kit with Tubular Control Arms and Bilstein 5100 Adjustable shocks up front and 5100 Bilstein shocks in the rear along with a 3” block replacing the 2” block. I've got 41.75" (up from 38.875") in front and 42.5" (up from 41") the rear.

Actually, this raised the truck more than I wanted but I had to be sure that after I spent all this money that the rubbing was gone. My wife bitches every time she gets into it. In retrospect, the 35" tires were just too big!

I just painted the calipers yesterday, so I haven't driven the truck since. Only time will tell. Amazon.com: G2 High Temperature Brake Caliper Paint System Set RED G2160 - High Gloss : Automotive

Awesome thanks for sharing the info.
mine sits at 41” front and rear. I like the look of a 12.50 but didn’t want to do any trimming. So far it’s a perfect balance for me.

You should try a 34x12R20lt, maybe that would work without any trimming.

Kept the 22" OEM wheels on my High Country and went with the Fabtech 4" lift with 285/55R22 Nitto Ridge Grapplers. Used 1-1/4 Spacers and still had to trim a bit, but not too much at all..

Nice look! Have you had any issues with 1 1/4" spacers?

This gentleman says he’s put a 285/65/20 set on his AT4. Stock. No rubbing. Haven’t seen anyone else put on this size tire. Can anyone confirm this?? I’m about to pull the trigger on a set for my ‘19 AT4 if so.

Did you do it? If so, has it killed MPG or acceleration? What tires did you choose? I want to put 295/65/20 on my 2021 AT4 with 1.75" Redi-Lift Level, don't want any more lift...

Took me forever but finally settled and pulled the trigger on my wheels/tires.

2021 GMC Sierra Denali, bone stock suspension. 22x10 +12mm offset Brink B206 Insurgent on 285/45r22 Michelin Defenders. I'm very pleased with the result! Various other mods of course but this covers the wheels/tires....thanks to all I've bugged with questions!
