The OEM transmission in a Polaris RZR XP Turbo has a habit of wearing out its bearings, and a failed bearing can take the case with it. This Premium Transmission Bearing Upgrade Kit replaces them with NACHI bearings made from Japanese steel and precision machined for a perfect fit, including an angular-contact thrust bearing that addresses the most common failure.
Highlights
- Complete upgraded transmission bearing kit
- Angular-contact thrust bearing prevents common idler shaft failure
- NACHI bearings made with Japanese steel
- Precision machined for a perfect fit
- Optional seal kit
- For OEM transmissions only
Solves the Idler Shaft Problem
The idler shaft pushes hard against its bearing, which can overheat and fail. An angular-contact thrust bearing is designed to take that sideways force without overheating or coming apart.
Option to Add Seals
If the transmission is apart, it's the right time to replace the seals too. Choose "Bearings + Seal Kit" to add two axle input seals, a clutch input seal and a front output seal.
Japanese Steel, Precision Fit
NACHI bearings are made with high-quality Japanese steel and machined to tight tolerances. They hold up to heavy loads from the gearset and a lead foot, which is exactly where stock bearings give out.
Cheaper Than a New Case
A failed bearing can wreck gears and crack the case. Replacing bearings proactively is far cheaper than rebuilding a destroyed transmission.
