Super ATV’s Complete Heavy-Duty Transmission for the Polaris RZR S 1000 is built for riders who push their machines to the limit.
Each transmission is made to order, rigorously tested, and designed to be stronger and more reliable than stock. Upgraded internals, lapped gears for perfect meshing, and a reinforced transmission case mean smoother operation, no break-in period, and confidence on every ride. From the inside out, this transmission is built to overhaul your machine and handle full-send abuse.
Strength comes from every component. A reverse chain that’s twice as strong as stock stands up to steep climbs and deep mud, while aircraft-grade 9310 alloy steel pinion and snorkel gears—paired with a 300M front output shaft - deliver unmatched durability and cool, smooth operation. A thicker pinion bearing retainer eliminates one of the biggest OEM weak points, and the reinforced case uses more material, added ribs, and gussets to improve strength and cooling.
To top it off, you can choose your gear reduction - stock, 12.5%, 25%, or 37.5% - to get the extra torque you need for bigger tires, heavier builds, and harder rides.
