Build the ultimate Ford F450 Super Duty diesel powered truck with this 2.5-inch radius arm lift kit with FOX 2.5 Performance Elite coil-over shocks from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35 inch Tires.
Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, heavy duty replacement radius arms, high strength 1-3/8 inch solid steel track bar for steering correction, sway bar relocation, brake line brackets and secondary FOX 2.0 shocks.
In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts and a matching set of FOX 2.0 Performance shocks.
FOX Performance Elite Coil-Over
FOX 2.5 Performance Elite shocks offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter shocks are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain.
The Dual Speed Compression Adjust adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.
HD Radius Arms
In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.
HD Adjustable Track Bar
Maintain proper handling and steering geometry with the BDS high strength adjustable track bar that allows you to recenter the front axle at a variety of lift heights. Built from 1-3/8 inch solid steel stock, the track bar comes pre-assembled with bushings and is ready to bolt into the factory mounting points.
