Enhance your Harley Davidson 80″ Evolution engine’s performance and longevity with this premium set of Hastings .010″ oversize piston rings. Engineered for optimal combustion control and oil economy, these rings are a crucial component for any engine rebuild or refresh, ensuring your motorcycle runs at its peak.
Description
These Hastings 80″ EVO .010″ oversize piston rings are meticulously engineered to restore and enhance your engine’s efficiency. The top compression rings feature a precision barrel face design, optimizing heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases. This design ensures maximum energy transfer to the crankshaft, boosting overall engine power. The second compression rings utilize a reverse torsional taper face, specifically promoting superior side sealing. This innovative design prevents oil from being forced under and behind the ring, significantly improving oil economy and reducing emissions. For unparalleled oil control, the set includes three-piece Flex Vent oil control rings. Their unique three-piece construction allows for rails with a small cross-sectional area, ensuring excellent conformability to the cylinder bore. This provides uniform pressure across four steel rails and two expanders, guaranteeing positive oil control. Proudly Made in the USA, these piston rings are a testament to quality and precision engineering, offering reliable performance for your Harley Davidson 80″ Evolution engine.
