Wossner Custom Piston Set for Polaris Pro R // SKU: WO-SK260201

Build the ultimate high-boost powerplant with the Wossner Custom Forged Piston Set for the Polaris RZR Pro R. Engineered specifically for high-horsepower forced induction applications, this custom piston set drops your static compression ratio to 10.5:1—providing the essential safety margin needed to run higher turbo or supercharger boost pressures without detonation.

Forged from high-strength aluminum, these pistons feature a dished design with precision-machined valve relief cuts and a lightweight profile to handle extreme cylinder pressures without sacrificing throttle response. To ensure longevity under punishing heat and RPM, each piston is finished with a low-friction Teflon skirt coating to protect your cylinder walls and minimize internal drag.

Key Features

• Boost-Ready Compression (10.5:1): Dished piston crown lowers compression to 10.5:1, making it the ideal setup for forced induction (turbocharged or supercharged) builds.

• Lightweight Forged Strength: Premium forged construction offers maximum structural integrity under extreme cylinder pressures while reducing reciprocating mass.

• Teflon Coated Skirts: Advanced low-friction coating reduces cylinder wall friction, lowers operating temperatures, and extends engine lifespan.

• Precision Valve Reliefs: Features custom-machined valve relief cuts to maintain optimal piston-to-valve clearance under aggressive cam profiles and high RPMs.
