OVERVIEW  
Upgrade your 2020–2022 Ford F-450 with the BDS 4" 4-Link Lift Kit, engineered for strength, stability, and premium ride quality whether you’re towing, hauling, or exploring off-road. This system replaces the factory radius arms with a heavy-duty 4-link setup that improves axle control, reduces binding, and delivers smoother suspension movement throughout the entire range of travel. While radius-arm kits offer excellent simplicity and durability, the 4-link design takes performance a step further by providing more consistent caster angles, enhanced articulation, and improved tracking under acceleration and braking, especially noticeable in larger Super Duty platforms like the F-450. For those seeking the ultimate setup, the system has been paired with front FOX 2.5 Performance Elite coilovers for exceptional responsiveness, control, and damping consistency. Whether you’re building a workhorse or a weekend adventure truck, this kit delivers the perfect blend of ride quality, capability, and durability.

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 ¼-inch 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 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.

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.
