Why We Make It Unmatched strength, style, and performance. Engineered to deliver all out strength, we've taken our traditional and made it exceptional with SuperATV's Radius Arms for the RZR RS1. Industry Leading Pivot Point What does this mean for you? SuperATV's Radius Arms for the RZR RS1 feature industry-leading Pivots. Unlike others, this design allows your machine to perform at its full potential by enhancing its natural movement rather than restricting it with a fixed end like the typical heim does. On the inner mount, SuperATV's radius arms have the ability to move vertically and horizontally without compromising your bushings, causing premature wear and tear. With full adjustability, you have control to add a lift kit, high-clearance trailing arms, or bigger tires without sacrificing ride quality. Strength and Durability With structural integrity that gives you the confidence to blast the whoops or take on the most heart thumping of hills, SuperATV's rear radius arms are constructed of an extra high strength steel that is thermo-mechanically rolled and typically found in truck chassis and cranes. At 4x the strength of stock and backed by the SuperATV's lifetime warranty, these radius rods for the RZR RS1 are guaranteed to take anything you can throw at them. NOTE: Voodoo Blue and Velocity Blue do NOT match Sky Blue.
