4" 2023-2026 Ford F450 Super Duty 4WD Radius Arm Fox 2.5 Performance Elite Coilover Lift Kit by BDS Suspension

BDS1226PPS and BDS1226PES 4" Radius Arm Coilover Lift Kits improve suspension strength, stability, and ride quality on Ford F-450 Super Duty trucks. Designed for drivers who want dependable performance with a simple, durable suspension design, this system replaces the factory stamped-steel radius arms with heavy-duty tubular radius arms that deliver improved durability, a confident steering feel, and reliable performance under heavy towing, hauling, or off-road use.

The heavy-duty BDS radius arms mount directly in the factory location and feature caster adjustment to properly align the front axle across a wide range of lift heights. Built from high-strength DOM steel, the arms restore proper suspension geometry while maintaining stable handling and reducing steering wander or uneven tire wear. OE-style rubber bushings at the frame mounts isolate noise and vibration while delivering smooth, maintenance-free operation.

Full-length BDS Pro-Ride coil springs provide the correct 4" lift height while maintaining smooth ride quality across both highway driving and rough terrain. To maintain proper steering geometry on lifted trucks, the system includes a forged drop pitman arm and heavy-duty track bar relocation bracket that keep the steering and track bar operating in phase while recentering the front axle.

Featuring Fox 2.5 Performance Elite Remote Reservoir Coil-Overs with DSC (dual speed compression) adjustments to fine-tune your ride with the turn of a dial. These coil-overs replace the factory coil springs and are optimized for performance and ride comfort. 

BDS1224PPS includes FOX 2.5 Performance Series coilovers engineered to increase wheel travel and improve damping control for both daily driving and off-road performance. BDS1224PES includes FOX 2.5 Performance Elite coilovers with external reservoirs and DSC (Dual Speed Compression) adjusters, allowing independent tuning of high- and low-speed compression for maximum suspension control across varying terrain.
