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 operation.
Upgraded Pinion Bearing Retainer
We 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 Reduction
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. margin-top: 24px; background: rgb(241, 243, 245); padding: 24px; padding-top: 16px;
Frequently Asked Questions (FAQ)
What makes a heavy‑duty RZR XP 1000 transmission better for hard trail riding?
A heavy‑duty transmission gives you stronger internals, smoother operation, and better reliability when pushing through rocks, mud, or hills. Ours uses lapped gears and upgraded 9310 steel on the pinion and snorkel gears for cooler, stronger performance under load.
How does SuperATV’s transmission compare to the stock Polaris RZR XP 1000 transmission?
We eliminate OEM weak points with upgraded gears, a thicker case, and a heavy‑duty pinion bearing retainer that keeps components aligned and prevents failures. It’s stronger in all the right places without unnecessary weight, giving you a more reliable drivetrain than stock.
How hard is it to install the SuperATV Complete Heavy‑Duty Transmission?
It’s a fully assembled, drop‑in unit, making installation straightforward for anyone comfortable working with driveline components. All seals, plugs, and the shifter shim are included, and you can access downloadable instructions or use our Virtual Mechanic for guidance.
Does this transmission help with running bigger tires or adding more weight?
Yes. Optional gear reductions give you more torque, making it easier to turn larger tires or haul added weight without stressing the drivetrain. Depending on your model, you can choose reductions like 12.5%, 25%, or 37.5% for major torque gains.
What’s upgraded in the reverse chain compared to stock?
We use a double reverse chain that’s twice as strong as the OEM chain, letting you confidently back out of deep mud or steep terrain. It’s built to handle the abuse that often causes stock chains to snap.
How does SuperATV improve the transmission case strength?
Our case has 68% more metal reinforcing critical areas like the snorkel tube and axle outputs, plus added support ribs and cooling fins. These upgrades help prevent cracking, reduce heat, and keep everything running tight and smooth under pressure.
Do I need to break in the transmission after installation?
No. The lapped gears in our transmission are mated during production, giving you a perfect mesh right out of the box. You can install it and hit the trail immediately with no break‑in period.
