Fabtech 17-21 Ford F250/F350 4WD Diesel 8in Rad Arm Sys w/4.0 & 2.25

The heart of this 8-inch lift system for your 2017-2020 Ford F-250 or F-350 Super Duty is Fabtech's tubular Radius Arms. These aren't your stock stamped arms; they're built with a reinforced tubular structure, dimple die side plates, and heavy gusseting, drawing on Fabtech's racing experience to handle rugged off-road use and provide additional strength to your truck's suspension.

What really sets this system apart is the attention to steering performance. Fabtech includes an extended-length Track Bar, unique to their 8-inch system, which is 4 inches longer than stock and offset to the driver's side. This design, paired with a stout 1/4-inch thick steel mounting bracket, helps bring the Track Bar and Draglink closer to parallel, reducing steering box push and allowing for full lock steering with up to 15.50-inch wide tires. The system also features massive Dirt Logic 4.0 remote reservoir coilovers. These bolt directly in place of your factory coil springs, offering outstanding damping for off-road adventures while maintaining a quality ride on the road. The giant 4-inch diameter aluminum reservoirs mount horizontally to allow for full compression travel, even with oversized tires.

Completing the package, you'll find a Trac Bar relocation bracket, a Pitman arm, sway bar drops, and a rear block and U-bolt kit. This comprehensive system is designed to provide increased strength and performance for your Super Duty, and it comes with a free 5-year, 60,000-mile powertrain warranty from Fabtech.
