Description

Polaris RZR and Ranger 800 engines rely on a strong, balanced bottom end to survive load and rpm. This complete bottom-end rebuild kit with pistons is designed for full rebuilds when wear or failure makes a partial repair risky. A 1-year REV6 parts warranty backs every component in this kit.

By replacing the crankshaft, pistons, bearings, seals, and gaskets together, you eliminate weak links inside the cases. As a result, the engine goes back together tighter, smoother, and ready for hard use.

THIS KIT INCLUDES

• HD twin crankshaft
• Upgraded pistons
• Main bearings and seal kit
• Counterbalance bearing
• Oil seal kit
• Complete gasket kit
