Performance Machine Off-Road Radius Rods are made from 6061-T6 billet aluminum and feature QA1 Spherical Bearing rod ends and 303 stainless steel precision machined misalignment spacers. Replacing the stock steel radius rods with PM billet aluminum radius rods add strength, and provides for full adjustment compared to the stock units. In addition, the Performance Machine Off-Road High Clearance Radius Rods' design increases ground clearance and off-road appeal.
