Fabtech 11-16 Ford F250/F350 4WD 4in Rad Arm Sys w/4.0 & 2.25

Fabtech is known for building tough suspension components, often drawing from their racing experience to create parts that can handle serious abuse. This 4-inch Radius Arm system for your 2011-2016 Ford F-250 or F-350 4WD is a prime example, offering a significant upgrade over the factory setup for both on-road comfort and off-road performance.

The heart of this system is Fabtech's tubular Radius Arms. They're built with a reinforced tubular structure, featuring dimple die side plates and heavy gusseting, making them much stronger than the stock stamped arms. This beefed-up design is crucial for handling the demands of off-road driving. To keep your axle centered and allow for full steering lock with wider tires (up to 12.50 inches on 5-inch backspace wheels), a heavy-duty track bar relocation bracket is included. Up front, the Dirt Logic 4.0 Coilover conversion replaces your factory coil springs. These coilovers bolt directly into the coil spring bucket without needing to remove it. The stainless steel body offers excellent corrosion resistance, and the large 4-inch diameter aluminum remote reservoir, mounted horizontally above the coilover, ensures full compression travel even with oversized tires.

For the rear, the kit includes a 5-inch lift block, extended bump stop brackets, and Dirt Logic 2.25 shocks to balance the ride quality with the front setup. This complete 4-inch system is designed to give your Super Duty a commanding stance and the capability to tackle tough terrain. It also comes with a free 5-year, 60,000-mile powertrain warranty for added peace of mind.
