Help Identifying lift (stock AT4 or aftermarket)

[MacPH]

Hey guys,  I'm trying to change the  look of my truck a bit and came across this 2019 carbonpro. Looks like it's running 33s on 20" wheels, but would appreciate anyone correcting or confirming me. other thing is, one buddy thinks this is a stock AT4 lift on 33s. Other one thinks it looks taller than the stock AT4s that GM puts out, mainly because those are running 18" wheels and they don't look like they have this kind of clearance. What do the pros think?

If you zoom in on the front tire you can see the Ready Lift UCA.  My guess is it is the 2" SST which has 2" in the front and adds another 1" in the back with a 3" replacing the stock 2" block.  I say that because the back looks higher to me.  Or it could just be the Ready LIft 1.75" leveling kit.

Good eye.  It does have the ready lift UCAs.  Look like 33 12.50 20 on the tire, glancing at the pic can you tell what offset (if any?)

 

I've been looking at the fuel siege 20x9 w/ +1 offset to get a little bit of a wider stance on the truck.  This truck looks more like a -18 or more.  Any ideas on the offset?

If you want wider you can go 20x10 -12mm offset. I have a set of LRG Rims on my truck in that size. I had to add a 5 mm spacer to clear the caliper bump so it's actually -17 offset. I'm running 275/60/20 on a stock Trail Boss. I had a set of 275/65/20 for a couple days and it rubbed on both sides on the felt of the rear part of the fenderwell.

Ok, thanks - good option.  That's a tiny spacer, was it hub centric and do you remember what brand you went with?  

[GETGONE]

Not hubcentric. They are billet ones with exact bolt patterns on ebay. They have 6x137.9 and 6x135(Ford pattern) both. They are way better than the cast slip fit White Knight brand I had picked up from AutoZone as a temporary pair to get the wheels on.

I put the Readylift SST 4" (comes with 3" rear blocks) on a custom and I sit about 2" taller up front than at4/trail boss and about 1" taller in the rear, I've parked beside several and noted the mirror height difference and box height difference. I've posted some pics here about it, maybe under my 4" readylift post? Anyhow, it's looking like that could be the end result of that trucks lift? https://www.gm-trucks.com/forums/topic/258291-4”-lift-vs-factory-2”-lift-side-by-side-pics/#comment-2592445 41.5" to finder lips all way round on 33's so if you can measure that truck it might tell you more? Although gmc fenders a bit different than my chevy fenders. I had to shorten my antenna by 6 3/8" to go under 7' garage frame. Keep in mind if you wanna fit in garages and 7' parkades, pretty sure you're not going under anything less.
