BDS 4 Inch Lift Kit w/ 4-Link & FOX 2.5 Coil-Over Conversion | Ford F250/F350 Super Duty (2011-2016) 4WD Diesel | Block Kit Rear

This variant includes a Block Kit rear lift option. Cast iron lift blocks are tapered for correct pinion angle, with an offset steel pin and hole to restore axle position. This eliminates the need for an additional lift block, reduces axle wrap, and creates a more controlled and stable feel while maintaining factory payload weight ratings.

Overview

This 4-inch lift kit with FOX 2.5 Performance Elite coil-over and 4-link conversion is designed for 2011–2016 Ford F250 and F350 Super Duty diesel trucks. The kit is engineered to improve stance, performance, and capability, providing clearance for up to 35-inch tires. Up front, the kit includes diesel-specific FOX 2.5 coil-over shocks, heavy-duty 4-link control arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, brake line brackets, and precision-tuned FOX secondary shocks. In the rear, the kit utilizes a high-strength fabricated lift block, a u-bolt flip kit for maximum ground clearance, brake line brackets, and a matching set of FOX Performance shocks.

FOX 2.5 Performance Elite Coil-Over

FOX 2.5 Performance Elite shocks are tuned and ready to install out of the box. These bolt-on 2.5-inch diameter shocks include a remote reservoir for additional fluid capacity to keep shocks running cool in rough terrain. The DSC adjuster provides 10 separate low-speed and 12 high-speed compression levels via two adjuster knobs. A black anodized aluminum reservoir increases cooling efficiency.

4-Link Conversion

The BDS 4-link conversion replaces the factory stamped steel radius arms to optimize suspension geometry for improved handling, strength, and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets with HD upper and lower control arms to correct axle positioning and limit caster change throughout wheel travel.

Steering Correction

A forged drop pitman arm minimizes steering angle change once lifted. A heavy-duty track bar drop bracket keeps steering components in phase through suspension travel while recentering the front axle.
