BDS SUSPENSION | 4" Lift Kit with Radius Arm | 80-96 Ford F-150 4WD | 502H / 504H / 506H / 529H

Description
Built to outperform, take your Ford 1980-1983 F100 and 1980-1996 F150 4WD truck to the next level with a 4-inch suspension lift kit with extended radius arms by BDS. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 33" tires.
Up front the lift kit includes Pro-Ride coil springs, axle pivot relocation brackets, extended radius arms, radius arm drop mounts, forged pitman arm for steering correction and precision tuned NX2 nitrogen charged shocks.
In the rear the base kit utilizes a high-strength lift block, longer u-bolts and a matching set of NX2 Nitro shocks.
Pro-Ride Coil Springs
A pair of full-length, vehicle-specific, Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.
Extended Radius Arms
In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. The extended radius arm system will reduce caster change through wheel travel creating a more capable and controlled feeling in the steering wheel both on and off road.

Warranty
BDS warranty coverage is for the original retail purchaser with proof of purchase. BDS hard parts and bushings have lifetime replacement coverage; finish and normal wear are excluded.
BDS NX2 and BDS/FOX Performance Series shocks have limited lifetime coverage excluding normal wear and oil seals. At BDS’s discretion, qualifying leaking seals less than two years old may be considered for repair or replacement.
FOX proprietary shocks and coilovers follow FOX warranty terms rather than the BDS warranty. Qualifying leaking seals less than one year old may be considered; other FOX concerns follow the FOX service process.
Properly maintained ball joints and tie-rod ends less than three years old may qualify, subject to the manufacturer’s conditions.
Remedies are repair or replacement at BDS’s discretion. Eligible warranty ground shipping is covered; removal, installation, expedited freight and consequential costs are excluded.
