Get a Better Reverse Chain It™s only a matter of time before it happens to you. You get into some tricky terrain, throw your Polaris RZR Trail S 900 in reverse, and feel your reverse chain snap. Now you either get dragged back to the trailer, or risk destroying the rest of your transmission. Upgrade to SuperATV™s Heavy-Duty Reverse Chain. It™s nearly twice the strength of stock and can keep your RZR Trail S 900 going strong. Unbeatable Strength The super single reverse chain we use is twice as wide and nearly twice as strong as stock. We know it™s that strong thanks to our cutting-edge testing and development equipment. It™ll get you through terrain that would destroy your stock reverse chain. Quality Construction Throughout The chromoly steel sprocket and shaft are precision made to ensure perfect pairing with the chain. It™ll run quieter and smoother than stock. You™ll have a stronger transmission that can take you anywhere you want to go.
