Fabtech 13-18 Ram 3500 4WD w/Factory Radius Arms 5in Radius Arm System w/Perf. Shocks

The factory radius arms on your 2013-2018 Ram 3500 4WD are a solid starting point, but this 5-inch system from Fabtech builds on that design to give you improved clearance and tire fitment. It features replacement tubular radius arms that are strengthened with exclusive dimple die side plates, offering both superior strength and a rugged look. These arms also provide increased caster, which is important for running larger tires and a lifted suspension.

Fabtech has paid close attention to the factory suspension's nuances. The stock front coil springs are retained, but mounted with angular steel spacers that preserve the factory spring bow. This bow is critical for Chrysler's specific alignment specs and ride quality, something flat spacers can't replicate. To keep the axle centered at the new ride height, a heavy-duty 1/4-inch thick steel front track bar drop bracket is included. You'll also find Fabtech's steel front bump extensions, a smart design that won't fail like some urethane stops found on other kits. The rear suspension gets a block and U-bolt system, also with bump stop extensions. This complete 5-inch system is designed to clear 37-inch tall tires and comes with Fabtech Performance Twin Tube shocks.

Installation involves drilling 10 holes but requires no welding. The kit includes a Trac Bar relocation bracket, Pitman arm, sway bar drops, and the rear block and U-bolt kit. With adjustable alignment cams at the axle on the radius arms, you can fine-tune your caster. This system is a well-built option for those looking to significantly increase their Ram 3500's capability.
