Torque Up, Pedal Down
Your Polaris has untapped power hidden right there in your engine, and all you need to get it out is a SuperATV Transmission Gear Reduction Kit. Your transmission is responsible for converting your engine’s power into horsepower and torque. Our 13%, 25%, and 38% gear reductions boost your torque for better acceleration and more power to the ground. That’s what Gear Driven Performance is all about.

13%, 25%, or 38% Reduction
If you want to run tires that are only a bit bigger than stock, a 13% gear reduction will work for you. Add heavier upgrades and bigger tires, and you’ll need that 25% or 38% option depending on just how big you’re wanting to go. Transforming your machine into a real monster? A gear reduction kit from SuperATV will help you get your rig's power back. What are you waiting for? We have the key to explosive acceleration and irresistible power right here.

Built for Strength
Our gear reduction kids are designed for high-level performance. They’re made from 8620 chromoly steel for unbeatable durability. The gears are heat treated and ground to the ideal shape, improving the overall contact pattern. That gives you a quieter ride and better performance.

Frequently Asked Questions (FAQ)

What does a transmission gear reduction kit do for my Polaris?

A gear reduction kit lowers your gear ratio to deliver more torque to the ground, which helps with bigger tires, slow‑speed crawling, and heavy loads. Our Polaris Transmission Gear Reduction Kit offers 13%, 25%, or 38% reductions that improve acceleration and low‑end power without sacrificing reliability.

How do I know which Polaris models this gear reduction kit fits?

We offer multiple OEM reverse‑shaft options so you can match the kit to your exact Polaris model and year. Just select your machine from the fitment list on the product page to confirm compatibility before ordering.

Is a SuperATV gear reduction better than using portals for more torque?

Portals add lift and reduction at the hub, while our transmission gear reduction kit delivers the reduction inside the gearbox for a more direct, efficient power transfer. If you want more torque without changing ride height or adding unsprung weight, our internal reduction is the cleanest solution.

What percentage gear reduction should I choose for my riding style?

Choose 13% for mild power gains with stock or slightly larger tires, 25% for bigger tires and mixed terrain, or 38% for maximum torque in mud, rocks, and deep technical riding. All three options boost low‑end performance and help your machine handle heavier loads.

How hard is it to install a Polaris transmission gear reduction kit?

Installation requires opening your transmission, so basic mechanical experience and standard shop tools are recommended. We provide full step‑by‑step instructions, and you can use our Virtual Mechanic service for live guidance if you want extra help.

Will this gear reduction make my Polaris slower on top speed?

Yes. Reducing your gear ratio increases torque at the cost of some top‑end speed. Most riders find the trade‑off worthwhile because the added low‑end power dramatically improves real‑world performance with larger tires or technical terrain.

What makes SuperATV’s gear reduction kit more reliable than stock?

We engineer our gears with improved contact patterns for smoother, quieter operation and long‑term durability. Every kit is built to handle the added stress of bigger tires and aggressive riding so your transmission stays strong.

Can I run oversized tires more easily with this kit?

Yes. The added torque from a 13%, 25%, or 38% reduction helps turn larger tires without straining your clutch or transmission. It restores the power you lose when upsizing and keeps your machine responsive on tough terrain.
