TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Features
- BDS Forged pitman arm to maximize steering radius at 4" of lift.
- BDS Radius arms are made from heavy duty DOM steel.
- BDS Radius arms restore proper caster angle, axle alignment, and suspension geometry, which helps maintain predictable steering, stable handling, and prevents wander or tire wear.
- Rather than rigid joints, the kit uses OE-style rubber bushings at the frame mounts. These bushings isolate noise and vibration , provide a smoother, quieter ride, and require no ongoing greasing or maintenance
- Choice of Fox shocks ranging from 2.0 to 2.5 Performance Elite.

Overview
Give your 2020–2022 Ford F-450 the lift it deserves with the BDS 4" Radius Arm Lift Kit, an ideal choice for drivers who want strength, simplicity, and outstanding everyday performance. While 4-link systems offer excellent articulation and fine-tuned geometry, a radius-arm setup shines when it comes to durability, straightforward design, and long-term reliability, qualities especially valued on heavy-duty trucks like the F-450. The heavy-duty radius arms from BDS are built to handle serious workload demands while maintaining predictable road manners, confident steering feel, and excellent stability under towing and hauling. This kit pairs perfectly with your choice of shocks: the proven BDS NX2 shocks, the FOX 2.0 Performance Series for a ride and handling upgrade, or the top-tier FOX 2.5 Performance Elite with DSC (Dual Speed Compression) adjusters for fully tunable control. And for those seeking even higher performance, the system can be optioned with front FOX 2.5 Performance Elite coilovers to deliver maximum responsiveness and comfort. Rugged, dependable, and easier on the budget, this BDS Radius Arm Lift Kit is the smart choice for drivers who want reliable performance without overcomplicating their suspension.
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.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.Questions
