Maximize the capability of your 2017-2019 Ford Super Duty diesel powered truck with this 4-inch lift kit with 4-Link 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 inch Tires.
Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, 4-link control arms with conversion brackets, 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.
4-Link Conversion
Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.
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.
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.
