Wiseco 84-99 Polaris 440AC Indy (2343M 2787CD) Piston Kit

The Wiseco SK1202 is a high-performance top-end rebuild kit for Polaris Indy 440 and Fuji Motor snowmobiles, featuring a 68.25mm piston size. It includes a high-performance ring kit and alloy pin for extended life and sustained power. The pistons are precision crafted and forged in the USA from aerospace alloy, offering a superior strength-to-weight ratio. This kit provides all necessary components for a complete rebuild, including Pro-Lite pistons for 2-stroke applications with CNC machined cam shapes for optimal HP, and 'race-ready' dome finishes for 4-stroke applications to improve combustion flow. Features like horizontal slot-pin oiling reduce friction and scuff resistance, and a pressure seal groove maximizes ring seal. Armor Glide skirt coating is included on 4-stroke race applications for reduced friction and noise.
