Here is my 2020 1500 4x4 Duramax. I have 2” Rough Country top coil spacer and 2”block on the rear with shock extension I put 35/12.50R20. I trimmed very minimal on the inner portion of the mud flap. Other then that i like the way it sits.

How much space do you have between the tire and upper control arm? I have a 2.5 front 2.0 rear and this looks like a great setup. And you just trimmed plastic and no metal? No rubbing?

No metal at all just plastic... very Very small portion And that was just temporary because I will be doing the mud flap delete on it. And between the arm and tires I have about 3/16”.... I have flex the truck pretty hardcore To test out... and No touching at all from tire to control arm.

2020 AT4, Readylift 2” SST with only the front lift. Rear sits .75-1 inch higher as is. I don’t think I got 2” from the lift. I was at 38.5” from ground to the line where the plastic black fender folds in, centered on the hub. After, with stock wheels/tires, I was at 40”. Now with 33’s, I’m at 40.5”. Wish I had measured from the center of the hub. Anyone have any measurements on a non At4 stock?

I have 2019 AT4 - also did Ready Lift SST kit - front was at 38" (both sides) before, now right at 40" (started at 40.5", but has settled about a 0.25" since).  Rear was 40" - now rear at 41" with rear blocks addded and Method NV wheels, so still a slight rake - without the block it was about 0.25" high in the front (but looked dead level with stock wheels).  I have painted fender flair from GM (not plasstic one like you).

 

Maybe they did not property set the preload, with spacer from SST kit - that should add the full 2", if preload was set correct.  May have that looked at. 

 

Photos below - is first photo after front level with stock wheels - no rear blocks - second is how it sits now with Methods and rear blocks added and third is the truck in stock form 1774283387_LeveledTruck.thumb.jpg.b8535f0f8e583d235494bdb8729f1b63.jpg

 

Methods and Blocks added to rear:

Nice truck! So your rear settled down as well? I wasn’t planning on installing the rear blocks due to the way it sits.

Rear did not settle - just blocks - so no settling - front did settle 0.25" or so.  I agree - like the way yours sits - looks great!

I ended up getting the non-LT 275/60r20 ridge grapplers. I wanted the 275/65/20 or 285/60/20 ridge grappler, but they only came in a LT load rating. I wanted to maintain that comfy factory ride for a little longer. When these tires wear out, I’ll probably go up to the larger size.

I want to go with same level/tire combo you have.  Any concern that using the bottom mount 1” kit will cause rubbing on the CV boot?

2020 Custom 4x4 5.3L
 

2.25” Pro Comp level kit up front. 
 

She’s actually currently sitting .75” higher in the front, so I’m going to add a 1” SDT rear block in a few weeks. 
 

Not for this thread, but just Adding the front level allowed me to fit 35x12.5x20 Atturo Trail Blade X/Ts. No spacers required. No rub. No trimming

It looks like it has plenty of room.
