Superlift's 4" Lift Kit with replacement radius arms for 2014-2016 Ram 2500 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" coil spacers negate the factory nose-down stance. The new track bar bracket keeps the axle centered while the bump stops, brake lines, and sway bar are relocated. Superlift'superide Shock are included, for all four corners, with this kit. Like all Superlift lift kits, the 4" Replacement Radius Arm Lift Kit for 2014-2017 Ram 2500 4WD is backed by our Limited Lifetime Warranty and Satisfaction Guarantee.
