This Radius Arm system is a heavy duty upgrade to the factory suspension and will provide additional strength to the vehicle.

They are superior in strength to the stock stamped arms. A heavy duty Track Bar relocation bracket centers the Super Duty axle under the vehicle and allows for full lock steering of 12.50 wide tires on 5" BS wheels. The front suspension receives the finest shock upgrade on the market with the Dirt Logic 4.0 Coilover conversion. It will provide outstanding damping capacity offroad with a quality on road ride. This Coilover bolts in place of the factory coil spring without removal of the coil spring bucket. The Dirt Logic is constructed with a stainless steel body for maximum corrosion resistance. It comes with a giant 4" diameter aluminum remote reservoir that mounts horizontally above the Coilover to allow for full compression travel with oversized tires. The rear suspension receives a 5" lift block, extended bump stop brackets and Dirt Logic 2.25 shocks for a balanced ride quality.
