BDS 8 Inch 4-Link Lift Kit w/ FOX 2.5 Performance Elite Coil-Over Conversion | 2017-2019 Ford F250/F350 Super Duty 4WD Diesel

Overview

This 8-inch 4-Link lift kit with FOX 2.5 Performance Elite coil-over shocks is engineered for 2017–2019 Ford F250 and F350 Super Duty diesel trucks. Designed to improve stance, performance, and capability, the kit includes everything needed to accommodate up to 40-inch tires. Up front, the kit features diesel-specific FOX 2.5 coil-overs, a 4-Link control arm conversion, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, brake line brackets, and custom-tuned FOX nitrogen-charged secondary shocks. A transfer case indexing ring and new transmission crossmember are included to allow use of the factory front driveshaft at this lift height. In the rear, the kit uses full-replacement BDS Glideride leaf springs, u-bolts, brake line brackets, and a matching set of FOX Performance shocks.

4-Link Conversion

The BDS 4-Link system converts the factory stamped steel radius arms to optimize suspension geometry for improved handling characteristics while adding strength and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets to mount HD upper and lower control arms, correcting axle positioning and limiting caster change throughout wheel travel.

FOX 2.5 Performance Elite Coil-Over

FOX 2.5 Performance Elite shocks deliver on-road comfort and off-road capability. Tuned and ready to install out of the box, these 2.5-inch diameter shocks include a remote reservoir for additional fluid capacity to maintain consistent performance in rough terrain. The DSC adjuster provides 10 separate low-speed and 12 high-speed compression levels via two adjuster knobs, with a black anodized aluminum reservoir for increased cooling efficiency.

T-Case Indexing

A precision-built transfer case indexing ring featuring ARP studs clocks the transfer case to improve the front driveline operating angle and allow use of the factory driveshafts at this lift height. A high-clearance transmission crossmember is also supplied for sufficient clearance.
