Description

This Pro Comp Radius Arm Kit is designed to provide a 4-inch lift. It's constructed from heavy-duty steel tubing with support gussets, offering a direct bolt-in replacement for factory radius arms. The kit features a durable textured black powder coat finish. It aims to correct suspension geometry when used with 2-4" lift kits, improve suspension strength, and provide higher ground clearance.
