X2 on the congrats and welcome to the forums!
anyways from what ive read the lift doesnt sacrifice your ride to much you just get more body roll. but your power goes to the sh**ter so be prepare to supercharge or drop in some new gears. but im no pro many guys on here can point you in the right direction. ask TIMGCO hes probably owned more hummer than years ive been alive
again good to have you!
