Complete Heavy-Duty Transmission for Polaris RZR XP 1000

Keep your adventures running strong with the SuperATV Complete Heavy-Duty Transmission for the Polaris RZR XP 1000. Designed for riders who demand maximum performance and reliability, this complete drop-in transmission is built to outperform and outlast your stock OEM unit. Engineered with upgraded internal components, precision lapped gears, and a reinforced case, it delivers consistent power transfer and unmatched durability on the toughest terrain.

Engineered for Unstoppable Performance

This heavy-duty transmission is more than just a replacement—it’s a complete upgrade. Every component is carefully designed to address the known weak points of the factory transmission. The upgraded reverse chain is twice as strong as stock, allowing you to power out of sticky situations with confidence. Whether you’re tackling deep mud, steep climbs, or rocky trails, this transmission is built to handle the abuse without faltering.

Precision-Built Gears and Strengthened Case

SuperATV uses 9310 alloy steel for the pinion and snorkel gears—the same high-strength material used in aviation applications. The 300M front output shaft ensures exceptional durability and power delivery, while the lapped gear design ensures smoother operation and reduced wear. The upgraded case features 68% more metal around critical stress points, reinforced ribs, and cooling fins to keep your transmission running cooler and longer.

Customizable Gear Reduction Options

Choose the level of performance that suits your riding style. Available in stock, 12.5%, 25%, and 37.5% gear reductions, this transmission allows you to optimize for torque, pulling power, or top speed. The increased gear reduction ratios are perfect for riders who run larger tires or regularly haul heavy loads, giving you the low-end power you need for extreme off-road conditions.

Built to Last and Easy to Install

Each transmission is fully assembled, tested, and ready for installation, saving you time and effort in the garage. It includes all necessary seals, plugs, and a shifter shim for a complete fit. With precision engineering and high-quality materials, this transmission strengthens your entire drivetrain and eliminates the weak spots that cause OEM failures. Designed, built, and tested to exceed factory standards, it’s the ultimate solution for serious Polaris RZR XP 1000 riders.
