im looking for a cheap suspension lift. Like a 4.5-6 inch. i already have a 3" body lift but i wanna take it off and put a suspension lift on it. can i modify a suburban kit to work? i found one of those for $377 shipped. if the front parts will work i can get some rear lift blocks for like $50. anyone done that before? like 6 months ago i found a 6" suspension lift for like $600 brand new but no luck finding it now. i just need some ideas on what i can do. also if i can find and the diminsions on the front end stuff i can make it. any opinions are welcomed and appreciated! thanks!
