Built to outperform, upgrade your 2017-2019 Ford F250 and F350 Super Duty diesel powered truck with this 4-inch radius arm lift kit and FOX 2.5 Performance Elite Coil-over conversion 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 37" tires.

Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, heavy duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets.

In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of FOX 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 DSC 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.

Steering Correction

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.

Rear Lift Option

5 Inch Block

Some F250/350 factory options increase the main leaf pack count from 2 to 3 leaf's (this is for top overload options only). Be sure to verify which factory leaf spring configuration your vehicle has and choose the appropriate option.
