Polaris RZR RS1 Premium Transmission Bearing Upgrade Kit

Reinforce Your RS1 TransmissionWhen 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 PowerThe 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 SteelThese 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
