so looking to put a 6 inch suspension lift on my 2004 Sierra Z71, but want some ideas on what ya'll think are good lift kits, and are there any good cheap ones out there if not then that is fine but never hurts to ask.
BDS Suspension makes great lifts (no torsion bar drop brackets, so that extra bit of clearance in center). That is my personal preference and would say BDS to anyone, but they are at the higher end of the price range. (6.5" lift approx $2100)
Rough country makes a half decent lift and I think they are $1000.
