Rear lift provided by a 4 Inch Block Kit — a high-strength fabricated lift block with longer U-bolts and brake line brackets. Shocks are NX2 Nitro Series: nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, 1-3/8-inch high-flow piston, dual-welded ends for increased strength, self-lubricating seals, and silver powder coat finish.
Overview
This 5-inch lift kit with 4-Link conversion from BDS Suspension is designed to raise the stance and improve the performance and capability of the 2020–2022 Ford F-250/F-350 Super Duty diesel-powered truck. The kit provides clearance for up to 37-inch tires and includes all necessary components for a complete installation. Up front, the kit features diesel-specific Pro-Ride coil springs, 4-link control arms with conversion brackets, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, brake line brackets, and precision-tuned nitrogen-charged shocks. The rear of the kit is available with either a fabricated lift block or leaf springs, along with longer U-bolts, brake line brackets, and a matched set of shocks.
4-Link Conversion
The BDS 4-Link conversion replaces the factory stamped steel radius arms to optimize suspension geometry for improved handling, strength, and stability. This bolt-on upgrade uses high-strength ¼-inch steel brackets that allow mounting of HD upper and lower control arms, correcting axle positioning and limiting caster change throughout wheel travel.
Pro-Ride Coil Springs
Full-length, diesel-specific Pro-Ride coil springs are included to provide the correct lift height and a smooth, predictable ride across various terrains.
Steering Correction
A forged drop pitman arm minimizes steering angle after the lift. A heavy-duty track bar drop bracket keeps the steering components in phase through suspension travel while recentering the front axle.
Features
- Easy, 100% bolt-on installation
- Pro-Ride dual-rate coil springs provide a smooth ride through any terrain
- Heavy-duty 4-Link control arms offer improved handling, stability, strength, and caster control during wheel travel
- Track bar relocation bracket and pitman arm maintain proper steering angles for improved handling
- Fabricated steel blocks (block kit option) provide a level stance from front to rear
- Standard NX2 Nitro shocks with vehicle-specific valving for better control
- Optional upgrade to FOX 2.0 Performance Series or FOX 2.5 Performance Elite shocks for maximum on- and off-road performance
- Fitment for up to 37-inch tires
Installation
- Estimated Time: 8–10 hours
- Difficulty: Difficult
- Special Tools Required: Cut-off Tool, Pitman Arm Puller
Important Notes
- Ford recommends replacement of the pitman arm nut each time it has been removed.
- 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 achieve 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 brake line clearance requirements. 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). BDS recommends having this performed prior to installing the lift.
- Fits SRW models only.
