Lift your vehicle 8" with the Superlift heavy duty front leaf springs. Also included are bushings, ubolts, brake line relocating bracket, front sway bar kit, steering arm, adjustable dropped drag link, rear block kit, add-a-leafs and 4 Superlift hydro shocks. Shock boots sold separately. 77.5-87 models require clearancing (machining) of the front driveshaft CV cluster to prevent binding. If vehicle has single exhaust, the cross-over pipe required modification to clear front driveshaft. Optional extended length brake hoses are recommended. Both driveshafts need to be lengthened.
