Built to outperform, upgrade your Ford Super Duty diesel powered truck with this 5-inch radius arm lift kit and FOX 2.5 Coil-over conversion from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 37" tires.
Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, heavy duty replacement radius arms, 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.
FOX 2.5 Coil-Over Conversion
FOX 2.5 coil-overs 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 coil-overs 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.
HD Radius Arms
In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
- Ford recommends the replacement of the pitman arm nut after each time it has been removed.
- If installed on a truck with a top-mounted overload spring, 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 wheels 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 37x12.50 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.
- Due to factory ride heights being lower on 2020 and newer model year trucks, the net lift you will gain with this kit will be 1" more than advertised. (EX. 4" kit will net 5" of lift)
