SuperATV Polaris RZR S UniBall
SuperATV created strong and stylish AtlasPro arms with unmatched features. To prevent weak links, they use a 4130 chromoly uniball instead of ball joints. The uniball stud is 140% larger than the OEM, measuring 17.9 mm instead of 12.7 mm. These arms are tough and durable, perfect for any battle. With a larger stud and meticulously heat treated materials, you have a uniball that is 400% stronger than your stock ball joint.
