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.

Pro-Ride Coil Springs

A pair of full-length Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.

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.

Important Notes

1. Fits diesel models only
2. These kits are designed for the F-450 style front end . They do not work with the standard Ford Super Duty F-250/350 axle width.
3. Vehicles with radius arm mounted ride height sensors will require BDS123303
4. Larger tires on stock wheels are not recommended due to brake line clearance required. Use recommended specifications listed in tire and wheel fitment section.
5. Installation requires a torque wrench capable of 405 ft-lbs.
6. Recalibration of your vehicles 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 the vehicle features such as lane keeping, lane departure, parking assistance, blind-spot detection, adaptive cruise control systems, and other functions as they did prior to installation. Please connect with your local dealership or ADAS service center. Similar to a wheel alignment, all charges and expenses that may occur from dealership calibrations and adjustments are the sole responsibility of the vehicle owner.
