Polaris RZR PRO XP Premium Transmission Bearing Upgrade Kit

Reinforce Your RZR Pro XP’s Transmission
Your Pro XP is packed with power. And when you slam on the gas, your transmission puts a ton of force on your OEM bearings. The stock ones tend to overheat and break down. That’s why you need our Polaris RZR Pro XP Premium Transmission Bearing Upgrade Kit. This kit is made up of NACHI bearings manufactured with Japanese steel that can take the pressure.

An Angular-Contact Thrust Bearing Won’t Blow Up
The more power going through your transmission, the more your idler shaft pushes against its bearing and your case. The stock bearing can eventually fail and blow out your tranny. Our angular-contact thrust bearing is specifically designed for that kind of force. It’ll take everything your transmission throws at it without failing.

Made with Japanese Steel
NACHI bearings are as tough as they get. They’re made from top-grade Japanese steel and precision-crafted for a perfect fit, so they can handle almost anything. From the pounding of your transmission’s gearset to your unrelenting lead foot, these bearings are ready for it all.

Add a Transmission Seal Kit
If you’re upgrading your gears, you should replace your seals too. Add our seal kit to keep mud, water, and trail from ruining your ride. Our kit replaces your axle input, clutch input, and front output seals with high-quality double-lipped seals that will last.
