Hey Adam, yes the Air Lift kit part # AL57388 does fit your 2021 GMC Sierra 1500 AT4 Alpine Rocky Ridge Edition. Are you wanting a compressor kit too?

@Adam You definitely don't have to go with a compressor kit and you can inflate it at your house with a compressor you have there now but an on-board compressor gives you the ability to inflate and maintain air pressure while driving which is pretty convenient. We have several options but I really like the Air Command part # F56VV which you can control with your smart phone or with an included remote.

@JamesonC no I don’t want that so this kit is good.. is there any change in my drive when nothing is hooked up to truck to tow and do the bags need to be 5psi at all times hauling or not

@Adam The ride quality won't be affected when the bags are aired down to the minimum of 5 psi. Then it will be exact same as stock. The minimum psi ensures that the bag doesn't get damaged. It makes it keep its shape at all times which prevents premature failure.
