Zone Offroad's 6" radius arm lift kit includes bullet proof 1/4" boxed radius arms with oversize greasable bushings for better strength, a better look and more ground clearance. Also included are engine specific coil springs, track bar bracket, pitman arm, sway bar brackets, front bump stop spacers, front & rear brake line brackets, steering stabilizer relocation bracket and 4 Hydro shocks. Shock boots sold separately. For the rear lift and to avoid stacking blocks, Zone includes a 5" cast iron block kit with integrated bump stops as well as dual add-a-leafs. This is a "top shelf" lift kit without the top shelf price.
