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.

It's A Whistler!
Size: Medium (Pack of 1), Style: Pack of 1
This Chuckit! Whistler Ball is basically a regular fetch toy that decided to become an annoying little teakettle mid-air. My dog goes absolutely nuts for it—every throw sounds like a tiny referee is shrieking "foul!" the whole way across the yard. He chases it harder than he chases the mailman, and bonus: I can actually find it in tall grass because it's screaming for help. Super bouncy, tough enough that he hasn't destroyed it yet (miracle), and now our walks sound like a low-budget horror movie.

Great buy
Size: 2 Count (Pack of 1), Style: Pack of 2
Easy to track balls. My dog loves them and I like that they whistle when you throw them cause some times my dog loses track of it in the air. This helps because they can hear where it's going. Will buy again.

My Dog's Favorite Balls
Size: 2 Count (Pack of 1), Style: Pack of 2
My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one.
We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find.
We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him.
The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all.
The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam.
We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.
