anyone know how much a 4\" spring/block lift kit weighs? I would like to estimate shipping charges. Thanks. It is the complete one on ebay from rough country. This kit works on 73-87 Chevy 1/2 or 3/4 ton Pickup, 73-91 1/2 or 3/4 Suburban, Fullsize Blazer, and Jimmy. This kit comes with Front luxuary ride double tapered leaf springs, poly bushings for the springs, ubolts, 4 inch block and ubolts for the rear, 4 Heckethorn Hydro 8000 shocks, raised steering arm, brake line relocator brackets, and nuts and bolts.
