Fabtech 17-21 Ford F250/ F350 4WD Diesel 8in Rad Arm Sys w/Coils & Stealth Shks

The heart of this 8-inch lift system for your 2017-2020 Ford Super Duty is Fabtech's tubular Radius Arms. Unlike the stock stamped arms, these are built with a tubular structure reinforced by dimple die side plates and heavy gusseting, drawing on Fabtech's racing experience for rugged off-road use. This design provides significantly increased strength over the factory components.

A unique feature of this 8-inch system is the extended length Track Bar, which is 4 inches longer than stock and offset to the driver side. This updated design, with its stout 1/4-inch thick steel mounting bracket, helps keep the Track Bar and Draglink closer to parallel. This geometry change is crucial for addressing the sensitive steering box in late-model Super Duty trucks, reducing steering push and allowing for full lock steering with up to 15.50-inch wide tires on 4.75-inch backspace wheels.

This comprehensive kit includes the heavy-duty radius arms, extended track bar, and Fabtech's Stealth Shocks, along with coils designed to work with the system. It's a substantial upgrade built to handle both on and off-road demands, providing increased strength and improved steering performance. The system also comes with a free 5-year, 60,000-mile powertrain warranty for added peace of mind.
