Made from 7075 Aluminum these Polaris RZR rear bearing carriers address the bearing push-out issue seen by racers and recreationalists alike. Zollinger Racing Products (ZRP) eliminated stress risers and added cross section in all the right spots to make this part truly race proven.

Push-out on the ZRP knuckle is over 2.5X the factory knuckle. This is achieved through superior USA Made material as well though the use of a ear-less snap ring, maximizing surface area. The stock cast knuckle took 22,000 PSI to press the bearing out, our 100% billet made in the U.S.A. knuckle took 63,000 PSI to press the bearing out.


Made from high quality, USA made, 7075-T6 Aluminum in our in-house state of the art machine shop.
