I have a 3" body lift on my 99' sierra. The only problem I am having, is I can't get to my spare tire. Im not sure if they make someting for that, but I really need it if they do.

 

My biggest complaint about the body lift is it seems to make the trucks ride extremely rough. I have owned two different trucks with 3in body lifts and both of them rode like holy crap rough after install. I had 33s on both trucks but after the install of the body lift I felt every little bump in the road and on top of that a speed bump would dang near break your back if you werent paying attention and hit it too hard.
