ZRP 7075 Capped Billet Rear Knuckle Set (Bearing Carrier) - RS1

ZRP Billet Rear Knuckle Set is made from 7075 Aluminum. These bearing carriers address the bearing push-out issue seen by racers and recreationalists alike. We eliminated stress risers and added cross section in all the right spots to make this part truly race proven.

Push-out on the ZRP capped knuckle is over 3X the factory knuckle. This is achieved through superior USA Made material as well though the use of a LH/RH threaded 17-4 retaining cap, 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 76,000 PSI to press the bearing out.

Set includes Polaris Heavy Duty Wheel Bearings and Cap Install Tool.

The radius rod through bolts are 12MM ONLY
