Yamaha YXZ UTV Uniball

Replacement Uniball Parts for Yamaha Boxed A-Arms
SuperATV spared no detail in the creation of these arms and tip to tip you will see strength, style, and features that are unmatched in the market. We know ball joints can be a weak link. To ensure a bulletproof design, AtlasPro arms are paired with a 4130 Chromoly uniball. Match top-of-the-line materials with a stud that is 140% larger than OEM, and you've got a set of arms that are Built for Battle. Important to note that the SuperATV uniball studs are not necked down; they measure 17.9 mm compared to the OEM ball joint stud at 12.7. With a larger stud and meticulously heat-treated materials, you have a uniball that is 400% stronger than your stock ball joint.
