Polaris RZR Trail S 1000 Complete Heavy-Duty Transmission by SuperATV

A Complete, Built-to-Order Transmission
Your machine is only as strong as the transmission inside it. That’s why we’ve worked so hard to make your Polaris RZR Trail S 1000’s tranny stronger and more reliable. SuperATV’s Complete Heavy-Duty Transmission comes with loads of upgraded internals, including a stronger reverse chain and perfectly meshed gears. Our complete, built-to-order transmission is strong enough to carry your RZR through the most brutal off-road conditions. Say goodbye to slipped gears and transmission issues—you’ve got SuperATV on your side now.

Your Reverse Chain Just Got Stronger
From harrowing hills to massive mud pits, the most fun rides are rarely the easiest. That’s why we doubled the strength of your reverse chain. You can throw our dual chain into reverse no matter what crazy situation you find yourself in—no worries about snapping your chain.

Perfect Pinion and Snorkel Gears
Thanks to expert design and 9310 alloy steel—AKA one of the toughest gear materials on the planet—our pinion and snorkel gear set can’t be beat. These gears are perfectly lapped, meaning they’re broken in together and guaranteed to mesh perfectly every time. This keeps everything running smooth and strong in all conditions. Throw in a 300M front output shaft and you’re left with the best Polaris transmission on the market.

A Better Pinion Bearing Retainer
Your weak OEM pinion bearing retainer tends to let the pinion gear pull away from the snorkel gear. This results in the gears chipping teeth, pulling apart, and breaking. Thanks to our bigger, redesigned pinion bearing retainer, that isn’t something you need to worry about. We’ve designed the retainer to keep your pinion gear held firmly in place.

Top-Quality Transmission Case
The icing on this transmission cake is our rock-solid case. It adds extra strength where you need it the most. We use 68% more metal on the axle output and snorkel tube, which is where OEM transmission cases tend to fail. We also added extra support ribs and gussets for added strength. Those extra ribs keep everything running cool, ensuring this is a transmission case that will keep you on the trails for years on end.

You Pick Your Gear Reduction
Extra torque lets you do more, especially if you’ve added extra weight or monster tires to your side-by-side. That’s why we offer multiple gear reduction options with this Polaris RZR Trail S 1000 transmission. Choose from stock, 12.5%, 25%, or 37.5% to get the perfect amount of torque for the way you ride. The larger the gear reduction, the easier it will be to turn your tires on rough, hair-raising rides.
