Fabtech 17-21 Ford F250/F350 4WD Diesel 6in Rad Arm Sys w/2.5 & 2.25

Fabtech is known for building robust suspension components that handle tough conditions. If you're looking to give your 2017-2020 Ford F-250 or F-350 Super Duty diesel a significant lift and improved off-road capability, this 6-inch Radius Arm System is a solid choice. It's designed to bolt directly onto your frame without requiring any cutting or welding, making installation more straightforward.

This system centers around their patented Radius Arms, which have a full tubular structure reinforced with dimple-die side plates. An adjustable alignment cam is built into the axle end, allowing you to fine-tune caster for proper wheel alignment after the lift. You'll get improved articulation and wheel travel thanks to the system's design, which also includes race-style 1-inch Uniballs in the heavy-wall links for superior strength. The thick 1/4-inch steel brackets ensure a solid connection to the frame.

Beyond the radius arms, this kit comes with everything you need to complete the suspension upgrade. You'll find a Trac Bar relocation bracket to keep your steering centered, a new Pitman Arm, Sway Bar drops to maintain proper sway bar function, and a rear Block and U-bolt kit to achieve the 6-inch lift height. The system also includes 2.5-inch diameter front coilovers and 2.25-inch diameter rear shocks, both featuring heavy-duty construction for consistent damping performance.
