Description:

Ride with Confidence
Say goodbye to your blown OEM tranny by upgrading to a SuperATV Complete Heavy-Duty Transmission. We made it stronger, more reliable, and specifically for your Polaris RZR Trail 900. You get perfectly lapped gears that require no break-in period, upgraded internals, and an ultra-strong case. Each transmission is made to order and undergoes vigorous lab and field testing before being shipped your way. Get ready to kiss your transmission issues goodbye and ride hard with the confidence that only SuperATV can provide.

Your Reverse Chain Just Got Stronger
We want you to enjoy all the crazy rides your heart desires, which is why we upgraded the reverse chain to be nearly twice as strong as stock. Our dual reverse chain is designed for the biggest hills and thickest mud pits. It can handle being thrown into reverse in the trickiest situations without breaking.

Upgraded Pinion and Snorkel Gears
You won’t find a tougher pinion and snorkel gear set anywhere else. Our gears are made from ultra-tough 9310 alloy steel. They’re perfectly lapped and broken in together, which ensures perfect mating and smooth, strong operation. Throw in a 300M front output shaft and you’ve got internals that beat the crap out of everything else on the market.

A Better Pinion Bearing Retainer
Our complete transmission replacement also comes with a heavy-duty pinion bearing retainer. The stock bearing retainer is one of the biggest weak spots on your OEM transmission—if it’s not strong enough, it can come apart, overheat, and explode. That’s why we made sure ours is way bigger and beefier. Your pinion gear will stay firmly in place, giving you a more reliable ride.

Top-Quality Transmission Case
These upgraded internal components are great, but they don’t amount to much if you don’t have a quality case holding it all together. Ours uses 68% more metal on the axle output and snorkel tube, and additional support ribs and gussets make it even stronger. It gives extra strength where your transmission needs it most, and those extra ribs keep everything running cool.

Want a Gear Reduction? Take Your Pick!
How does some extra torque sound? With this Polaris RZR Trail 900 transmission, you decide how much of a gear reduction you get. Choose from stock, 12.5%, 25%, and 37.5% to get the perfect amount of torque for your ride. If you’re carrying more weight or running bigger tires, that extra force will be a lifesaver—especially in mud and on rough trails.

        Nice material, holds collar shape well.
        Color: Wine Red, Navy Blue, Black, Size: Medium
        Good value for the money. You can machine wash and dry on low heat, in my opinion. Laying flat is too much of a pain.
