Complete Transmission
When your transmission stops, you
stop. That’s because this masterpiece of machinery makes your UTV do what you
want it to with the perfect amount of power. And SuperATV has made it better,
stronger, and more reliable with our Complete Heavy-Duty Transmission for the
Polaris RZR XP 1000. With upgraded internals and a better case, our
transmission will power through the trails that made your OEM case explode.

Upgraded Reverse Chain
We upgraded our reverse
chain to make it twice as strong as stock. The double reverse chain on our
tranny lets you throw it into reverse whenever you need to. It can handle
thick mud and hills where your stock reverse chain would snap.

Upgraded Pinion and Snorkel Gear
We upgraded the
materials on our pinion and snorkel gear set to 9310 alloy steel. That’s the
same gear material used in airplanes. And the front output shaft is made with
300M—one of the strongest steel alloys you can get. Plus, our pinion and
snorkel gear are lapped, meaning they’re mated and broken in together as part
of the production process. This means smoother, cooler, and stronger

Upgraded Pinion Bearing Retainer
also include our heavy-duty pinion bearing retainer. Your stock bearing
retainer is one of the biggest OEM weak spots. When it’s not strong enough, it
lets your snorkel and pinion gear pull apart, overheat, and explode. Our
thicker retainer holds your pinion gear in place to prevent any explosions.

A Better Case
Better gears don’t amount to a
hill o’ beans if you don’t have a better case to hold it all together. We made
our tranny stronger in all the right places but only added one pound of
material over stock. Our snorkel tube and axle output has 68% more metal, plus
additional support ribs and gussets. Those gussets and fins also help to keep
your transmission cooler. We did everything we could to make this the
strongest case you can get.

Choose Your Gear

Ready to bump your torque way up? Depending on your
model, you can choose between stock, 12.5%, 25%, and 37.5% gear reduction for
your transmission. A bigger gear reduction means more torque for adding bigger
tires and carrying more weight. It also means impressive pulling power through
rough trails and deep mud pits. If you’re serious about playing hard in your
RZR, upgrade to a bigger gear reduction.
