I haven’t but according to tiresize.com my 3.23 gears need to be changed to 3.42 to be okay with my 34.25” tires. I think 3.73 and you will be fine. 4.10 might be overkill especially on gas mileage.

I have had the 1.5” level for a year now and about 12k miles. I would still like to upgrade the UCA just because of the failure’s I have seen on FB but you are correct all the one’s I have seen failed are 2” level spacers which is what may be helping my controls stay okay so far. Hope it stays that way until I upgrade

The upper control arms only fix the upper ball joint angles but the cv angles are not addressed at all. That’s why I kept my 1.5” motofab level and plan to simply upgrade my control arms. The 2” kits do come with control arms already but they also push those cv angles another half inch and I like how my angles currently look. Now 35x12.5r18 are pretty wide depending on the brand...so they may hit on the upper ball joint which could be fixed with some wheel spacers. My 12” wide tires are about 3/8” away from the ball joint. They 35s are typically 34.5” tall so you would probably rub on the fender liners or mud guards. My 34.25” tall tires have about a 1/2” on each side at full lock. I guess what I am trying to say is go look on tiresize.com or the manufactures website for the actual specs so you can see what are it’s true dimensions. Sent from my iPhone using Tapatalk

The duratracs are narrower at 11.8” than my cooper evolution MT at 12” however they are slightly taller at 34.3” vs 34.25” not a big difference but without a level they may rub. Although as you mentioned there has been members running this size with no trouble and no level as you wish. You have the trailboss which I believe has more space. You could have discount tire test fit them if you have one near. Or if you decide to order them, well worse case scenario you slap in a level perhaps just a 1” to help with the clearance.

1.5” motofab level. With the GM “lift” that this the AT4/TB come with my ball joints were completely flat. After the 1.5” lower spacer they moved a bit still look good. The cv angles also were flat before and look decent after level. The 2” from ready lift does correct the control arms with new replacement but pushes the cv angles even more. So I plan to replace the UCA in the future perhaps but maintain my 1.5” level. Sent from my iPhone using Tapatalk

1.5” motofab level Cooper Evolution MT 295/70 Zero rub Sent from my iPhone using Tapatalk

Have been running motofab level for a year now on stock duratrac. Just installed 295/70 cooper evolution MT and they clear very well. They are 61.5 lbs which are pretty light compared to others in the same specs weighing on 70+....they measure 34.25”x12”....I could install a 1/4” or 3/8” wheel spacer but I think I will leave it like those for now. No rubbing on UCA so far all good. Sent from my iPhone using Tapatalk

Got a new set of tires...cooper evolution mt 295/70....heck of a deal from Walmart at $196/piece. Also added new gm black lug nuts and black center caps. Sent from my iPhone using Tapatalk

I also have a 5.3.AT4....sorry I know you asked for 6.2....but just wanted to help. Mine came with the stock duratracs and I get about 15.3mpg mixed city/hwy.....I added a 1.5” leveling motofab lower spacer and the mpgs remained the same. I was expecting a difference but it did not affect them at all. Been running the level with the stock tires for about 10k miles now. Sent from my iPhone using Tapatalk

Do you have a part number for those center caps? they look so glossy...shop chevy parts has them but the image shows them in a matte black. I want the GMC red like you originally had to put on my 18" AT4 wheels.

Checked out your tire specs and they come out to 34.29x11.77...I am quite astonished that they are rubbing as they are narrower than the mastercrafts. Have you had the truck aligned? Sent from my iPhone using Tapatalk

Mastercraft or Evolution MT have the same specs 34.25x12...scroll to the first pages and you will find some pic I posted for a member from here. Sent from my iPhone using Tapatalk

I have the motofab 1.5 bottom spacer installed. When I installed the spacers I did not remove the axle nut however I didn’t have the remove the strut as it is the bottom spacer. The axle did pop out as I dropped down the spindle and I got scared...I installed the bottom spacer and then turned the axle straight again and pushed it back into place all was good and it did give me room to install new bolts. There are 1” motofab kits on ebay that should fit it says up to 2019 but it should fit even on 2020 as my kit said 2018 and fits my 2019. Sent from my iPhone using Tapatalk
