BDS Suspension 4 Inch Radius Arm Lift Kit FOX 2.5 Performance Elite Coilover Conversion Ford F250 F350 Super Duty 4WD Diesel (2008–2010)

Upgrade the stance, ride quality, and off-road capability of your 2008–2010 Ford F-250 or F-350 Super Duty 4WD diesel truck with the BDS Suspension 4 Inch Radius Arm Lift Kit featuring FOX 2.5 Performance Elite Coilover Conversion. Designed for premium on-road comfort and aggressive off-road performance, this complete system provides increased ground clearance and clearance for up to 35-inch tires while maintaining predictable handling and suspension control.

Up front, this system replaces the factory suspension with diesel-specific FOX 2.5 Performance Elite coilover shocks mounted in the factory coil bucket location. These race-proven shocks feature remote reservoirs and DSC adjusters, allowing precise tuning of both low-speed and high-speed compression for a highly adaptable ride across varying terrain. The system also includes secondary FOX 2.0 shocks for enhanced damping performance and control.

To improve durability and suspension geometry, BDS includes heavy-duty tubular replacement radius arms that provide caster correction while maximizing ground clearance. Steering geometry is corrected using a forged drop pitman arm and track bar relocation bracket, helping keep steering components properly aligned and the front axle centered throughout suspension travel.

In the rear, the system utilizes high-strength fabricated lift blocks or optional replacement leaf springs, depending on the selected configuration. Longer U-bolts and matched FOX Performance shocks complete the rear suspension for balanced ride quality and dependable performance.

Engineered as a complete bolt-on suspension upgrade, this BDS system delivers premium FOX suspension performance, improved handling, and the durability needed for demanding off-road use while preserving daily drivability.
