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

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?”

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.  
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.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
