Designed for 2017-2022 Ford F250 and F350 4WD models, Fabtech’s 6″ Radius Arm Lift Kit is built to meet the extreme on- and off-road demands of Super Duty enthusiasts. This heavy-duty system is a complete upgrade to the factory suspension, delivering increased strength, improved suspension control, and aggressive styling.
At the core of this premium lift kit are Fabtech’s legendary tubular Radius Arms. Developed from extensive off-road racing experience, the tubular construction provides exceptional durability while maintaining a smooth, compliant ride quality. This design allows the suspension to confidently handle rugged off-road terrain while remaining comfortable and controlled during daily driving.
A heavy-duty Track Bar relocation bracket combined with a dropped Pitman Arm properly centers the front axle under the vehicle. This correction restores proper steering geometry and allows full lock steering with 12.50 wide tires on 5″ backspacing wheels.
The front suspension is equipped with Fabtech’s Dirt Logic 2.5 Remote Reservoir Coilovers, engineered to withstand punishing off-road conditions while delivering a plush, controlled highway ride. In the rear, lift blocks with integrated bump stops provide the required lift height while maintaining factory ride quality and load-carrying capacity.
The redesigned Radius Arms feature a reinforced side plate and bold laser-cut Fabtech logo, giving the suspension a modern, aggressive appearance that stands out both on and off the trail.
This lift kit is backed by Fabtech’s free 5 Year / 60,000 Mile Powertrain Warranty.
