BDS1520F | BDS Suspension 4" Lift Coil-over With Radius Arm & Fox Shocks Lift Kit For Ford F-250 / F-350 Super Duty 4WD | 2017-2019 | Diesel

Building on the 4" radius arm lift systems, these 4" coilover systems integrate FOX 2.5 remote reservoir coilovers and FOX 2.0 shocks to take your trucks performance and capability to the next level.

Up front a pair of heavy duty replacement radius arms are supplied to correct caster, improve ground clearance, and offer more strength than the factory stamped steel units. These arms are built from 1-3/4" OD -10GA DOM tubing with support gussets and are formed inward to allow for additional clearance of oversized tires.

They incorporate factory style 3-1/4" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. These work in combination with the specially tuned FOX 2.5 factory series remote reservoir coilovers. These coilovers are preset right out of the box for optimal performance with the weight of the 6.7L Powerstroke diesel engine and are an easy install using the supplied frame and axle mounting brackets.
