Superlift's 4" Lift Kit with replacement radius arms for 2013-2017 Ram 3500 4WD Pickups features set of massive, high clearance, precision engineered, tubular radius arms designed to bolt right into the factory mounts giving your ride a truly custom look and an easy install. These heavy duty radius arms utilize a press fit Cleveite rubber bushing for superior vibration damping and durability. The 4" lift also contains new, progressive rated, coil springs and a dropped pitman arm that works in conjunction with our track bar relocation bracket to ensure proper steering geometry and track bar phasing. Replacement bump stops prevent suspension over compression and the sway bar and brake lines are relocated to prevent bar pre-load. In the rear, 2" blocks negate the factory nose-down stance. Superlift'superide Shock are included, for all four corners, with this kit.
