Wiseco 2312M06950 High Performance Piston Kit 69.5mm Standard Bore Snowmobile

The Wiseco 2312M06950 is a high-performance forged piston kit designed for Ski-Doo snowmobile engines at a standard bore size of 69.5mm. Built for both trail and racing applications, this piston delivers the strength and reliability that Wiseco is known for across decades of powersports performance.

Constructed from high-silicon aluminum alloy, the 2312M06950 offers superior tensile strength compared to cast pistons, resisting heat and stress under demanding riding conditions. The computer-engineered piston skirt profile stabilizes the piston within the cylinder bore, minimizing cylinder wall friction while maximizing horsepower and torque output.

Key Features:

• Forged high-silicon aluminum alloy construction for maximum strength and durability
• 69.5mm standard bore diameter — ideal for stock displacement rebuilds
• Computer-engineered skirt profile for reduced friction and improved power transfer
• Optimized forging design promotes maximum heat transfer away from the combustion chamber
• Kit includes piston, rings, wrist pin, and circlips
• Oversize bore pistons available for cylinder sleeving applications
