Fabtech 17 Ford F450/F550 4WD Diesel 6in Rad Arm Sys w/Coils & Perf Shks

This is the Fabtech 6-inch Radius Arm Lift System designed specifically for the 2017 Ford F450 and F550 4WD Diesel models. If you're looking to enhance your Super Duty's capability for both on-road driving and demanding off-road adventures, this system offers a substantial upgrade over the factory suspension. It's built to handle the unique requirements of these heavier-duty trucks, providing the added strength needed for larger tires and rough terrain.

The heart of this system is Fabtech's patented Radius Arms, featuring a full tubular structure reinforced with dimple-die side plates for exceptional strength. An adjustable alignment cam at the axle allows for precise caster adjustments, ensuring proper wheel alignment after the lift. The kit includes American-made coil springs engineered for a comfortable ride quality, whether you're cruising on the highway or tackling trails. To keep the front axle centered with the 6-inch lift, a 1/4-inch thick steel bracket repositions the factory track bar. You'll also find a forged steel Dropped Pitman Arm, designed to exceed factory specifications for strength, and 1/4-inch thick steel drop brackets that reposition the front sway bar to prevent binding throughout the suspension's extended travel range. The system also includes brake line brackets to relocate the factory lines without opening the brake system, and steering stabilizer brackets to retain the factory F450 or F550 long travel stabilizer, helping to reduce tire shimmy.

Out back, steel rear lift blocks replace the factory units to achieve the desired lift height without compromising ride quality or load capacity. American-made U-bolts are included to securely attach the rear differential. Completing the package are extended length twin-tube Performance shocks, offering a balanced ride for highway use and the durability for off-road excursions. This comprehensive kit provides a full suspension transformation, ready for whatever you throw at it.
