Polaris RS1 REM Finish & Machining Service
Upgraded Bronze Bushing for Polaris RS1 differential pinions. The OEM bushing is soft and can allow for pinion deflection. This bronze bushing replaces the soft OEM bushing at the rear of the pinion.
RS1 Ring and Pinion REM finish and machining service. OEM casting burrs cause RS1 Ring gears to crack. We machine down the ring gear to remove the casting burrs then we REM finish the ring and pinion. The REM finish process removes micro stress risers. This service ensures the best performance out of a RS1 ring and pinion. Many of the top Rock Bouncers are running our REM finished Ring and Pinions.
After you order the service we will email you instructions on where to ship your ring and pinion for the service.
