The Zone Offroad 2005-17 Ford Super Duty radius arm upgrade package features tough replacement radius arms that will work with most 4 & 6" suspension lifts. Made of fully boxed 1/4" steel and utilizing large 2-1/2" greasable urethane bushings, these arms are a considerable upgrade in strength from the stock arms. The arms bolt directly into the factory mounts, and position the axle for the proper caster and wheel location. The lower axle mount utilizes our popular cam lock design, making it adjustable for 4" or 6" of lift. These arms will improve ground clearance and strength, not to mention appearance vs. a standard radius arm drop bracket system.
