Polaris 800 Bottom-End Rebuild Kit with Pistons (2011–2017) Ranger/RZR

This Complete Bottom End Rebuild Kit fits Polaris Ranger and RZR 800 models from 2011–2017. When crankshaft wear, bearing damage, or lower-end noise develops, this kit provides the major rotating components needed to restore strength and reliability.

What This Kit Includes

• HD Twin Crankshaft
• Upgraded Piston Kit
• Main Bearing and Seal Kit
• Counter Balance Bearing
• Oil Seal Set
• Complete Gasket Kit

First, the HD twin crankshaft restores lower-end durability. Next, the upgraded piston kit supports proper compression. In addition, new bearings and seals stabilize rotation and oil control. As a result, your Polaris 800 bottom end runs smoother and more reliably under load.

This kit includes a 1-year parts warranty. If you only need sealing and bearing components, see our Polaris 800 Master Gasket, Seal & Bearing Kit. For warranty details, review our warranty policy, or contact our team through the contact page.
