Product Details

The Wiseco SK1078 is a complete Pro-Lite Top End Kit engineered for cast iron bore, fan-cooled Polaris snowmobile engines. Bored 1.00mm oversize to 73.00mm, this kit provides everything needed to overhaul or rebuild the top end of your engine in a single package — eliminating the hassle of sourcing individual components.

Kit Includes:

  • Forged piston(s) — stronger and lighter than OEM cast alternatives
  • Piston rings — precision-fit for optimal compression and oil control
  • Wrist pins — hardened for durability under high-stress conditions
  • Circlips — retaining clips to secure wrist pin installation
  • Top end gasket set — complete sealing solution for the rebuild

Key Specifications:

  • Bore Size: 73.00mm (1.00mm oversize)
  • Piston Type: Pro-Lite Forged
  • Bore Type: Cast Iron
  • Cooling: Fan Cooled
  • Note: Cylinder sleeves must be purchased separately. Will not fit Widetrack models.

Wiseco's Pro-Lite forged pistons are manufactured using a high-strength aluminum alloy forging process, delivering improved heat dissipation and resistance to detonation compared to stock cast pistons. This kit is designed for a direct, straightforward installation during your next top end rebuild.
