Raise the bar on your 2017-2019 Ford F250 and F350 Super Duty diesel truck with this 6-inch 4-Link lift kit and FOX Performance Elite coil-over conversion 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 38 Inch Tires.
Up front the lift kit includes FOX 2.5 coil-over shocks and mounting brackets, 4-Link control arm conversion, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets.
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 a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of 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 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 Dual Speed Compression Adjust 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.
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.
