Take your Ford Super Duty diesel truck to the next level with this 9-inch 4-Link lift kit from BDS. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 40 inch Tires.

Up front the lift kit includes diesel-specific Pro-Ride coil springs, 4-Link control arm conversion, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, bump stop extensions, stainless steel braided brake lines, NX2 steering stabilizer, and custom-tuned nitrogen charged shocks.

At this height, the transfer case needs to be indexed to allow use of the factory front driveshaft so an indexing ring and new transmission crossmember are supplied. In the rear this kit utilizes full replacement Glideride leaf springs to provide full lift height and increased capacity with a built in overload spring, u-bolts, brake line brackets and a matching set of NX2 Nitro or 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 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.

Pro-Ride Coil Springs

A pair of full-length, diesel-specific, Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.

T-Case Indexing

At this height, driveline adjustments are necessary to allow the use of the factory driveshafts so a precision-built transfer-case indexing ring featuring ARP-studs can clock the transfer case and improve the front driveline operating angle. Additionally, a high clearance transmission crossmember supplied to allow sufficient clearance.
