Gear Driven Performance Kit

The Polaris RZR has some hidden power right in your engine and all you need to get it out is a Super ATV Transmission Gear Reduction Kit! Your transmission is what is responsible for converting your engines power into horsepower and torque. These kits come in 12-38% gear reductions to boost your torque for better acceleration and more power to the ground! Upgrade your Polaris RZR XP 1000 with our Super ATV Transmission Gear Reduction Kit today!!
Stage 2 Gear Set:
The Stage 2 gear set is 12% or 25% gear reduction based on what model of RZR you have. The 12% gear reductions are amazing for getting a boost to your torque and acceleration whether you're running just stock tires or tires that are just a few inches bigger. If you're going with even larger tires a 25% gear reduction will give you the torque and power you need!
Stage 3 Gear Set:
Super ATV's Stage 3 gear set gives you a flat 13% gear reduction no matter what model of RZR you're running. That is the perfect torque boosting reduction for a pretty standard tire upgrade even for models that come with a reduction kit from the factory!
Combine Stages for Bigger Gear Reduction:
Are you wanting/needing even more? Then combine Super ATVs Stage 2 and Stage 3 gear reductions. These can be used in the same transmission at the same time for a 25% or 38% gear reduction! If you're wanting to run with monster tires and do wheelies too, combing gears is the way to go for you!
