Polaris RZR PRO XP Premium Transmission Bearing Upgrade Kit

Premium Transmission Bearing Upgrade Kit for the Polaris RZR PRO XP

Replace the factory transmission bearings in your Polaris RZR PRO XP with a premium upgrade kit featuring NACHI bearings made from Japanese steel. These bearings are built to tighter tolerances and higher material standards than the factory components, addressing the bearing failures that sideline stock transmissions.

NACHI Bearing Quality
This kit uses NACHI bearings manufactured from Japanese steel to exacting tolerances. NACHI bearings are recognized across motorsport and industrial applications for their superior load ratings, tighter radial clearances, and longer service life compared to standard replacement bearings.

Complete Coverage
The kit includes a full set of transmission bearings for the Polaris RZR PRO XP — every bearing in the gearbox is covered in one purchase. Replacing the complete set at once ensures uniform wear characteristics and eliminates the risk of a surviving old bearing failing shortly after a partial rebuild.

Seal Kit Option
Available with an optional transmission seal kit that replaces every seal in the gearbox alongside the bearings. When you're already deep enough in the transmission to replace bearings, fresh seals prevent the leaks that develop when old seals are disturbed during reassembly.

Direct Replacement
Every bearing in this kit matches the factory dimensions, bore size, and load rating specifications for the Polaris RZR PRO XP transmission. They drop directly into the existing bearing seats with no modifications to the transmission case or shafts required.
