Wossner Piston Kit 75mm Polaris 300 4x4 2x4 1994-1995 8095D050

Stock pistons can't handle the demands of high-performance 2-stroke applications—especially in a 300cc four-stroke platform that sees sustained high RPM and load cycling. The Wossner 8095D050 piston kit delivers the thermal stability and durability you need to maintain reliability without sacrificing power output. Built on decades of German engineering expertise, this complete kit gets you back on the track with confidence.

This is a complete, bolt-on solution that includes everything necessary for proper piston assembly: the piston itself, compression rings, wrist pin, and circlips. The 4032 T6 forged aluminum alloy resists thermal creep and maintains dimensional integrity under extreme operating conditions. A permanent skirt coating minimizes friction losses while reducing piston rock, translating to smoother engine operation and extended component life.

Wossner's design process leverages Finite Element Analysis (FEA) to optimize ring sealing geometry, skirt profile, and load distribution—meaning every millimeter is engineered for performance and longevity. The T6 heat treatment cycle ensures the aluminum reaches peak hardness and thermal resistance, a critical advantage in high-load racing environments where engine temperatures routinely exceed 200°C.
