Polaris RZR RS1 Premium Transmission Bearing Upgrade Kit

Reinforce Your RS1 Transmission
When you put the power down, your transmission puts the pressure on your bearings. Your OEM bearings tend to overheat and fail when you're running at full tilt. That's why you need to upgrade to our Polaris RZR RS1 Premium Transmission Bearing Upgrade Kit. We use NACHI bearings that are built for strength and longevity with Japanese steel. With better bearings made with better materials, you can ride solo with confidence.

An Angular-Contact Thrust Bearing Built for Power
The idler shaft in your RS1 transmission has a nasty habit of pushing against the stock bearing until it breaks. That bearing just can't handle the force. That's why we use an angular-contact thrust bearing. It's specifically designed to take the pressure from your idler shaft without overheating or falling apart.

Made with Japanese Steel
These NACHI bearings are built to last. They're made from high-quality Japanese steel and precision-engineered for a flawless fit, so tough rides won't stop them. Whether it's the pressure from your transmission's gearset or your lead foot on the pedal, these bearings won't let you down.

Add a Seal Kit
Don't upgrade your transmission bearings and reuse the same old seals. Add a transmission seal kit to ensure you're getting the best possible upgrade. Besides you've already done all the work required to replace them!
