Polaris RZR Pro XP Rear Spindle Bearing Carrier

CNC out of billet aluminum in our state of the art machine shop in Green Bay, Wisconsin.

Our unique design uses a steel ring fastened to the inside of the carrier to hold the bearing in place.  This eliminates the common issue of bearing push out.

Finished in a black anodized coating, the images in raw billet are for display only.  

Price is per side and includes an installed OEM HD bearing 3515090
