Wossner Custom Pistons Set for Polaris Pro R // SKU: WO-SK260201
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. Kit Includes (4) Wossner Custom Forged Pistons (4) 93mm Performance Ring Sets (4) Heavy-Duty Wrist Pins (8) Wrist Pin C-Clips Product Specifications SKU: WO-SK260201 Compatibility: Polaris RZR Pro R Bore Size: 93mm Compression Ratio: 10.5:1 (Optimized for Boost) Material: Forged Aluminum Skirt Coating: Teflon
