Product Details

The Wiseco PK1651 is a complete top-end piston kit engineered for the Polaris Trail Boss 350 ATV, featuring an 82mm bore diameter (639M). This kit provides everything needed for a professional-quality overbore or top-end rebuild, ensuring your engine returns to peak performance specifications.

Kit Includes:

  • Forged piston — stronger and lighter than cast alternatives, built to withstand high heat and stress
  • Piston rings — precision-fit for proper sealing and compression retention
  • Wrist pin — hardened for durability under reciprocating load
  • Circlips — retaining clips to secure the wrist pin in place
  • Top-end gasket set — complete sealing package for a leak-free reassembly

Wiseco's forged piston technology delivers superior strength-to-weight ratio compared to stock cast pistons, making this kit an ideal choice for both restorations and performance rebuilds. Each component is manufactured to tight tolerances for proper fit and long service life.
