lift kit

Hey everyone, I just got a 1500 that came with a Pro Comp 6" lift kit already installed rolling on 35x12.5 20's(its a mall crawler). My vision for the truck is to make it into an overland rig, and as FUNCTIONAL as possible. I was wondering if it is doable to take the lift kit off and replace it...

Hey I have a 2004 quadrasteer suburban 2500 and am looking to put a lift kit preferably 7-8 inches and can’t find any lift kits past 5 almost and wondering if anybody has bought actual quadrasteer lift kits that tall or what they have done to modify the lift to work??
