2020 F350 Dually 4 Radius Arm Suspension Lift System - Nitro Shocks - GAS
For optimal strength, ground clearance and styling the 4" radius arm system is the way to go. This complete kit is designed to lift and level the stance with room for up to 37" tires to be installed. Front lift comes from a pair of front full length coil springs to pair with your choice FOX 2.0 adventure series shocks for optimal ride quality. The front axle is repositioned using a pair of heavy duty replacement radius arms that bolt in place of the factory stamped steel arms. These arms are built from high strength 1/4" steel, boxed and fully welded with large 2.5" greaseable bushings to isolate road vibrations and improve ground clearance over drop bracket kits. Steering correction comes from a forged drop pitman arm to improve operating angle while a massive 1/4" steel fabricated track bar drop bracket is used to recenter the front end and keep the steering linkage angles in phase for predictable handling. Also included for the front are sway bar relocation brackets, brake line drop brackets, bump stop extensions, and single steering stabilizer kit. In the rear these kits retain the factory overload equipped leaf springs and lift is provided via a replacement lift blocks and longer u-bolts specific to the DRW models. Finishing off the rear is a rear brake line bracket and tour choice of rear gas shocks to match the front of the truck.
