Get More Torque
Your Polaris ACE gives you absolute freedom to hit the trail whenever and wherever you want. If you don’t want anything to stop you, you need to get a Transmission Gear Reduction Kit from SuperATV. It boosts torque with up to a 38% gear reduction to give you more power to the ground. So whether you go big with monster tires or just want to make sure stock won’t stop for anything, our gear reduction kits will get you there.

Stage 2 Gear Set
Depending on your model, you can get a 12% or 25% gear reduction with our Stage 2 gear set. Whether you need 12% for stock and slightly larger tires or 25% for going big, this gear reduction will give you torque that makes you grin.

Stage 3 Gear Set
Our Stage 3 gear set gives you a 13% gear reduction no matter what model your ACE is. It’ll give you a torque boost you can feel and that power to the ground you need. When you lose performance by upgrading your tire size by a couple inches, this 13% gear reduction will get your power back.

Combine Stages for a Bigger Gear Reduction
You can use both Stage 2 and Stage 3 gear sets at the same time in your ACE’s transmission to maximise your power. With up to a 38% gear reduction, you’ll be rolling on monster tires and they’ll feel like stock. You haven’t felt power until you hit the gas with both Stage 2 and Stage 3 gears in the same case.
