Improve the ride on your 2023-2025 Ford Super Duty diesel with this BDS Suspension 5" radius arm lift kit, with clearance for up to 37" tires. Up front it runs diesel-specific Pro-Ride coil springs, heavy-duty tubular radius arms with caster adjustment, a forged drop pitman arm and track bar drop bracket for steering correction, sway bar relocation, brake line brackets and tuned NX2 Nitro shocks.

Notes

• Vehicles with radius arm mounted ride height sensors require BDS123303.
• Ford recommends replacing the pitman arm nut each time it is removed.
• Use a small pitman arm puller to remove the drag link joint and steering stabilizer taper.
• Trucks with a 2-piece rear driveshaft may require carrier bearing drop kit BDS123402.
• Due to taller factory ride height, Tremor models will not net full advertised lift; final ride height matches standard models.
• Larger tires on stock wheels are not recommended due to interference with brake line, radius arm and sway bar. Use the specs 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 406 ft-lbs.
• Vehicles with leaf spring ride height sensors must select the rear block option.
