Quick Ship SKU #: BDS-1551H BDS 4" Radius Arm Suspension System 20-22 Ford 6.7L Powerstroke F250/350 4WD

Are you ready to gain some altitude in your SuperDuty coupled with increased suspension performance? Whether your truck stays on the pavement or you like to hit some dirt on the weekends, this kit from BDS will not only deliver additional ride height for larger tire fitment and ground clearance, but also a better ride, no matter the conditions. As far as quality...no cheap coil or radius arm spacers here, only fine tuned replacement coils and stout, stellar looking radius arms with this kit!

At the heart of this system is a pair of heavy duty radius arms built to withstand whatever abuse you can throw at them. Built from 1-3/4" OD -10GA DOM tubing with support gussets, these replacement arms are far superior to the factory stamped steel units. They use a high clearance design for extra ground clearance and are formed inward to allow for additional clearance of oversized tires. They incorporate factory style 3-1/4" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and reposition the front axle to correct caster angle.

The additional 4" of lift comes from a pair of full length diesel specific ProRide coil springs. These paired with your choice of BDS NX2 series gas shocks or the precision tuned FOX 2.0 performance gas shocks offer a smooth ride and improved control over rough terrain. To improve steering angles a forged drop pitman arm is supplied with an integrated drag link flip. Used in combination with the 1/4" thick heavy duty track bar drop bracket will position the front axle and keep the track bar angle in phase with the steering for improved handling. Also included for the front suspension are a pair of sway bar relocation brackets, bump stop extensions, brake line relocation brackets and a NX2 series steering stabilizer with mounting bracket. Out back a 4.5" fabricated block with integrated bump stop wing is used in place of the factory block on the F250 or F350 to level the stance. Longer black e-coated u-bolts and your choice of NX2 or FOX 2.0 shocks round out this 4" radius arm lift system.

Shock Options

Choose between custom valved BDS NX2 series or Fox 2.0 series gas charged monotube shocks to outfit the front and rear of your Powerstroke.

• BDS NX2 Series - BDS NX2 series gas shocks offer impressive performance on and offroad. They use a nitrogen charged, twin tube design with 10-stage velocity sensitive valving for lightning fast dampening and superior control. This results in: increased stability for improved handling, longer front end and tire life, less nose dive on severe braking, less squat on hard acceleration, smoother ride control without harshness.
• Fox 2.0 Series - Fox 2.0 performance series shocks have been tuned and tested by both Fox and BDS Suspension to maximize performance specific to each application and to every BDS Suspension system. The basic shock design is based on proven Fox Racing Shox race products, but re-designed to maximize the ride quality, handling, and control of your BDS equipped truck or jeep, whether on or off the road.

Front Adjustable HD Track Bar

These track bars are a massive upgrade to the factory unit, constructed from 1-3/8" solid steel stock reinforced with gusseted ends to handle whatever on-road and off-road abuse you can through at it. Adjustments are made at the 1-3/8"-12 fine threaded center turnbuckle with pinchbolt ends to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front end components and is designed to easy installation without the need to clearance the factory frame and axle mounts. Both ends use high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Parts come with a high quality textured black powdercoat finish for a great look and excellent corrosion resistance. The are designed for use on 0-4" of lift and can be used in combination with most aftermarket track bar brackets to be used on taller lift heights.
