Fabtech 17-21 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 2017-2020 Ford Super Duty is a prime example, designed to upgrade your factory suspension and add significant strength for both daily driving and rugged offroad adventures. The core of this system is Fabtech's tubular Radius Arms, which are reinforced with dimple die side plates and heavy gusseting, making them much stronger than the stock stamped arms.

To keep your front axle perfectly centered and allow for clearance of up to 12.50-inch wide tires on 5-inch backspace wheels, this kit includes a heavy-duty Track Bar relocation bracket. Up front, the Dirt Logic 4.0 Coilover conversion replaces your factory coil springs without needing to remove the spring buckets. These coilovers feature a stainless steel body for excellent corrosion resistance and a large 4-inch diameter aluminum remote reservoir that mounts above the coilover, ensuring full compression travel even with oversized tires. For the rear, you'll get a 5-inch lift block, extended bump stop brackets, and Dirt Logic 2.25 shocks to balance the ride quality.

This comprehensive 4-inch Radius Arm system with Dirt Logic 4.0 Coilovers is a well-built upgrade for Super Duty owners looking to improve their truck's stance and capability for tackling tough terrain. The system also comes with a free 5-year, 60,000-mile powertrain warranty for added peace of mind.
