Description

A Complete Transmission
You're not the kind of rider to slow down when you face a challenge. The best way through is to put the pedal down and gountil you blow your OEM transmission. Install SuperATV's Heavy-Duty Complete Transmission on your Polaris RZR 900. It's better than your stock tranny so you can ride hard without dealing with slipped gears or transmission problems. With perfectly meshing gears, a beefed-up case, and completely upgraded internals, this transmission pushes as hard as you do.

A Better Reverse Chain
Stock RZR transmissions run with a weak single reverse chain that breaks often. Ours uses a double chain that's nearly twice as strong as OEM. You can throw it in reverse in thick mud and steep inclines without worrying about popping it.

Pinion and Snorkel Gears That Know How to Part
Our pinion and snorkel gear set is the toughest you can get. They're made with 9310 alloy steelone of the toughest gear materials on the planet. They're perfectly lapped, which is a fancy way of saying they're already broken-in together. You get cool, quiet, and smooth performance from the first ride. Combine that with the 200M front output shaft, and you know this transmission won't pull any punches.

Beefed Up Pinion Bearing Retainer
There's a fatal flaw in stock Polaris RZR transmissions that you might overlookthe pinion bearing retainer. The weak OEM one lets your pinion gear pull away from the snorkel gear. When that happens, they can chip teeth and grenade out the side. Our bigger, beefier pinion bearing retainer doesn't let that happen.

A Rock Solid Case
The transmission case holds everything together. If it flexes at all, gears could strip and you're left without a functioning RZR 900. Ours is thicker and stronger. With 68% more metal around the OEM weak points of the snorkel tube and axle output, it's a case you can count on. Plus, we added support ribs and gussets to further stiffen and cool the transmission. We made sure it's a transmission case that will take you anywhere.

Choose Your Gear Reduction
This transmission comes with the option to run a stock, 12.5%, 25%, or 37.5% gear reduction so you have the torque and more power you want. Extra torque will have you jumping off the line quicker, pulling through mud or over hills easier, and turning bigger tires like they're stock.
