You don't ride on anyone's terms but your own. When enhancing your Polaris RZR Trail S 900 for greater capability, SuperATV provides the answer with the GDP 4" Portal Gear Lift. Regain your torque with a 15% or 30% gear reduction and benefit from unmatched strength with cast or billet aluminum housings.

Understanding Dual Idler®
After extensive research and development, SuperATV introduces dual idler gear portals that stand out from the competition.
