WSM Top End Rebuild Kit for Polaris Standard Bore

The WSM Top End Rebuild Kit for Polaris in standard bore is built to restore compression and performance in Polaris ATV, UTV and personal watercraft engines. Each kit is a top end kit (also called a piston kit or top end rebuild kit). It gives you the core components for refreshing the top end of a worn engine with stock-size pistons.

Key Features:

• Standard (stock) bore: pistons are sized to original specifications, for engines that are within tolerance and don't need an oversize piston
• Complete top end components: kits generally include the piston, rings, wrist pin, clips, and top end needle bearing, plus the gaskets needed for the rebuild
• Made to OEM specifications: pistons and rings follow the original design for proper fit and interchangeability
• Coated piston skirts: a non-abrasive coating on the piston walls is intended to reduce friction and heat and extend piston life
• Precision manufacturing: built to strict tolerances for reliable compression, sealing and durability
