Polaris RZR170 2009-2017, Transmission Pinion Gear Shaft Kit & Pinion Cover Kit 

This replaces the rear transmission pinion cover and the pinion gear shaft. The rear cover has a bearing added, the shaft has a long nose to connect with the added bearing to support the pinion gear and shaft to help strengthen the transmission case and help prevent it from cracking. A new gasket may be required if it is damaged while removing the main transmission cover for installation. Can be done without removing the engine from the car.

More Information:

Load on the transmission from the chain pulling on it under power, is the main reason this area of the transmission fails. Under this load, the stock upper motor mount can flex and also fail, along with causing the stock pinion shaft to deflect and break the transmission housing. Along with this pinion upgrade kit, the upper motor mount right next to the transmission also needs to be reinforced. This pinion shaft upgrade kit will replace the stock pinion shaft, which does not have a wide bearing spread. This upgraded shaft and cover, widens the bearing spread drastically to help keep the pinion shaft from deflecting like it does stock.
