Product Description

More Torque for Bigger Tires on Your Defender HD9

When you upgrade your Can-Am Defender HD9 with bigger tires, your machine has to work harder to get moving. A SuperATV Transmission Gear Reduction Kit gives you the extra torque you need to handle those upgrades without sacrificing performance. With 10%, 20%, and 30% reduction options available, you can pick the gear ratio that matches how you ride. It’s an easy way to get your machine feeling strong again.

10%, 20%, or 30% Reduction

Not every Defender HD9 build needs the same amount of gear reduction. A 10% option works well for mild tire upgrades, while heavier setups with bigger tires may benefit from a 20% or 30% reduction to help bring back lost torque. Pick the reduction that fits your build and keep your Defender ready for whatever the trail throws at it.

Serious Durability

Our gear reduction kit is designed to give your Can-Am Defender HD9 reliable performance ride after ride. The gears are made from tough 8620 chromoly steel and carefully heat treated and ground for maximum strength and better gear engagement. That means less noise, smoother power delivery, and a kit that’s ready for whatever you put your Defender through.
