Designed for 2017-2022 Ford F250 and F350 4WD models, Fabtech’s 8″ Radius Arm Lift Kit is engineered to handle 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 steering control, and superior ride quality.
At the core of this premium lift kit are Fabtech’s legendary tubular Radius Arms. Developed from extensive off-road racing experience, the tubular design provides exceptional durability while maintaining a smooth, compliant driving experience. The redesigned arms feature reinforced side plates and bold laser-cut Fabtech logos, giving the suspension a modern, aggressive appearance that stands out on and off the trail.
Exclusive to this 8″ system is Fabtech’s extended length Track Bar solution, specifically engineered to address the hyper-sensitive steering characteristics of late-model Super Duty trucks. This groundbreaking design keeps the Track Bar and Drag Link closer to parallel than factory geometry, significantly reducing steering push, bump steer, and tire shake.
The extended Track Bar is four inches longer than stock and mounts to a stout 1/4″ thick steel frame bracket offset to the driver side. This configuration allows full lock steering with 15.50 wide tires on 4 3/4″ backspacing wheels while maintaining proper steering control.
Rear lift is achieved using a combination of a rear add-a-leaf and lift blocks, providing the required height while preserving factory ride quality and load-carrying capacity. This suspension system delivers maximum performance, durability, and control for Super Duty owners who demand the best.
This system is backed by Fabtech’s free 5 Year / 60,000 Mile Powertrain Warranty.
