Important Notes
Ford recommends the pitman arm nut is replaced prior to pitman arm installation. If installed on a truck with a top-mounted overload spring, with an overload spacer block taller than 1-1/8" UBT4027 (Qty: 4) is required. Use a small pitman arm puller to remove the drag link joint and steering stabilizer taper. If your truck is equipped with a 2-piece rear driveshaft, a Carrier Bearing Drop Kit may be required: BDS123402. Due to the taller factory ride height, Tremor models will not net the full advertised lift height. The final ride height will be the same as standard models. Larger tires on the stock wheel are not recommended due to the brake line clearance required. Use recommended specs listed in the wheel and tire fitment section. Minor trimming may be necessary for clearance of 38x13.50 tires on certain wheel setups. Installation requires a torque wrench capable of 405 ft-lbs. Some trucks with a rear driveline vibration may have a recall from Ford regarding the rear axle. (Safety Recall 21S31) Due to the recall procedure, BDS recommends having this performed prior to installing the lift.

Manufacturer's Description
Maximize the capability of your dual rear wheel Ford F350 Super Duty diesel powered truck with this 4-inch lift kit with 4-Link and FOX 2.5 Performance Elite Coil-over conversion from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your dually truck up right with clearance for up to 38" tires.
Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, 4-link control arms with conversion brackets, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets.
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 ¼-inch 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 DSC 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.
