Overview
Featuring an industry-leading pivot point design, these radius arms allow for enhanced natural movement of your machine, preventing premature wear often associated with fixed-end designs. The adjustable heim joints offer full adjustability, enabling you to accommodate lift kits, high-clearance trailing arms, or larger tires without compromising ride quality. Constructed from extra high-strength steel, these arms offer exceptional structural integrity and a superior strength-to-weight ratio, all backed by SuperATV's lifetime warranty.
