Overview

The SuperATV Heavy-Duty Complete Transmission is a robust replacement for your Polaris RZR 900's stock transmission, designed to withstand aggressive riding. It features a reinforced case with 68% more metal in critical areas, a stronger reverse chain that is twice as strong as OEM, and a beefed-up pinion bearing retainer to prevent gear damage.

Internal components are upgraded with a snorkel gear set made from 9310 alloy steel and a 300M front output shaft. The gears are meticulously lapped for quiet, smooth, and efficient operation from the start. This transmission is available with various gear reduction options, including stock, 12.5%, 25%, and 37.5%, to provide increased torque for quicker acceleration and the ability to turn larger tires. It is offered in a complete, assembled, drop-in configuration, built to order and tested to ensure reliability. Note that this transmission does not include turf mode.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
