Single Piston Ring Set 96.5mm Bore

The Single Piston Ring Set 96.5mm Bore by WISECO is a precision-engineered engine component designed for serious engine builders and performance mechanics who demand reliable compression sealing and oil control. This ring set addresses the critical need for proper ring clearance and blowby reduction in high-performance and rebuilding applications where OEM tolerances may not meet modern performance standards. Whether you're tackling a full engine rebuild, upgrading a stock bottom end, or restoring a vintage engine to factory specifications, this 96.5mm bore ring set provides the durability and precision fit that separates professional-grade work from amateur shortcuts.

WISECO piston rings are manufactured to exacting tolerances using premium alloy materials that resist wear, oxidation, and thermal stress during extended engine operation. The 96.5mm bore specification ensures proper ring-to-cylinder wall contact pressure, which directly impacts compression retention, oil consumption, and overall engine efficiency. WISECO's design minimizes blow-by gases escaping into the crankcase, reducing contamination of engine oil and prolonging bearing life. The ring set's compact weight of just 0.09 lbs reflects the precision engineering required for minimal inertial mass while maintaining structural integrity across varying RPM ranges and load conditions.

This single piston ring set is essential for anyone boring or resizing cylinder blocks to the 96.5mm standard, whether for street performance, vintage restoration, or engine rebuilding on import or domestic platforms. Installation requires careful ring gap measurement, proper piston groove cleaning, and methodical ring installation using appropriate ring compressors to prevent breakage. Mechanics and enthusiasts should verify their specific piston manufacturer's recommendations to ensure compatibility with groove dimensions and ring clearances. WISECO's reputation for quality makes this ring set a trusted choice among professional engine builders and DIY enthusiasts seeking dependable long-term engine sealing performance.
