TB/AT4 “leveling kit” with “GM 2 inch suspension lift” on SLT X3

[Kdembo03]

I currently have a 2020 Sierra SLT X31 and was wondering if I got the 2” GM Suspension Lift that is offered through GM installed, does my truck now become the same as the TB/AT4 in regards to the suspension? And if so, if I wanted to level the lift afterwards, would I need to get the leveling kit that is offered for the TB/AT4 with the new UCAs?

Yes and yes.

after you get the OEM lift kit installed you have effectively a Trail Boss / AT4 and when you're searching for additional items for it you will need to make sure that you buy the trail boss/ AT4 version

Oh ok, awesome, that makes sense! Thank you, I appreciate it!

Honestly man, I’ve got an X31 SLT and I went with the AT4 lift.  If I could go back, I’d do the rough country 6” for the same cost.  It’s not that big a difference honestly.

That’s good to know! My only thing with that is, I wasn’t really trying to go all that much larger (if at all) on tires and imo I feel that anything less than a 35” tire on a 6” lift looks kinda funny. How’s the ride with the “GM 2” lift?”

Actually I've never compared those two but you're right the cost is very similar (assuming you don't live in Alaska where they charge $2,200 to install the kit) and both of them don't ride that well so.

If you hop into a trail boss it's literally exactly the same parts.
