Rear lift utilizes replacement leaf springs: multi-leaf progressive design for a smooth ride, correct pinion angles, reduced axle wrap, and maintained factory payload weight ratings. Rear shocks are FOX 2.5 Performance Elite: 2.5-inch impact extruded aluminum body, massive 7/8-inch hard chrome plated heat-treated alloy steel shaft, external reservoir, DSC Dual Speed Compression Adjuster, and fully serviceable design with a 1-year manufacturer's warranty.
Overview
This 5-inch lift kit with 4-Link and FOX 2.5 Performance Elite coil-over conversion from BDS Suspension is designed to improve stance, performance, and capability on the Ford F250/F350 Super Duty diesel-powered truck (2023–2026) 4WD. The kit includes clearance for up to 37-inch tires and contains all components necessary for a complete installation.
Up front, the kit includes diesel-specific FOX 2.5 coil-over shocks, 4-link control arms with conversion brackets, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets. In the rear, the kit utilizes a high-strength fabricated lift block or leaf spring option (depending on variant selected), longer u-bolts, brake line brackets, and a matching set of FOX Performance rear shocks.
4-Link Conversion
The BDS 4-link converts the factory stamped steel radius arms to optimize suspension geometry for improved handling characteristics while adding strength and stability. This bolt-on upgrade uses high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning and limit caster change throughout wheel travel.
FOX 2.5 Performance Elite Coil-Over
FOX 2.5 Performance Elite shocks are tuned and ready to install right out of the box. These 2.5-inch diameter bolt-on shocks feature a remote reservoir for additional fluid capacity. The DSC (Dual Speed Compression) adjuster provides 10 separate low-speed and 12 high-speed compression levels via two adjuster knobs. A black anodized aluminum reservoir increases cooling efficiency.
Steering Correction
A forged drop pitman arm minimizes the steering angle once lifted, paired with a heavy-duty track bar drop bracket to keep steering components in phase through suspension travel while recentering the front axle.

- Difficulty: Difficult
- Special Tools Required: Cut-off Tool, Pitman Arm Puller, Torque Wrench capable of 405 ft-lbs
Important Notes
- Ford recommends the pitman arm nut is replaced prior to pitman arm installation. 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 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.
- SRW Models only: Recalibration of your vehicle's Advanced Driver Assistance System (ADAS) cameras, radars, light detection and ranging (LiDAR), and other sensors may be necessary by your local dealership or ADAS service center. This will ensure proper functionality of lane keeping, lane departure, parking assistance, blind-spot detection, adaptive cruise control systems, and other functions. All charges and expenses from dealership calibrations and adjustments are the sole responsibility of the vehicle owner.
- Vehicles with radius arm mounted ride height sensors will require BDS123303.
- Vehicles with leaf spring ride height sensors must select the rear block option.
