Hastings Piston Rings 80" Evolution Standard for Harley Davidson

Upgrade your Harley Davidson Evolution engine with the high-performance Hastings 80" Evolution Standard Piston Rings. Engineered for durability and optimal engine function, this complete set provides superior sealing and heat transfer for a wide range of Harley Davidson models.

Description

Designed for the demanding conditions of motorcycle engines, these Hastings 80" Evolution Standard Piston Rings are a crucial component for restoring or enhancing your engine's performance. This comprehensive kit includes top compression rings, second compression rings, and oil control rings, providing a complete solution for two pistons. The top compression rings feature a barrel face and cast coating, specifically engineered to optimize heat transfer from the piston to the cylinder wall while effectively controlling combustion chamber gases. This ensures maximum energy transfer to the crankshaft, boosting overall power and efficiency.

The second compression rings utilize a reverse torsional taper face design, promoting exceptional side sealing. This innovative feature prevents oil from migrating under and behind the ring, leading to improved oil economy and reduced consumption. Complementing this, the reverse twist ring with a taper-machined face creates a precise scraping edge, similar to a positive twist torsional ring. For meticulous oil management, the three-piece Flex Vent oil control rings are designed with a small cross-sectional area, allowing for superior conformability to the cylinder bore. This design, combined with four steel rails and two expanders, delivers uniform pressure and ensures positive oil control, minimizing blow-by and maintaining engine cleanliness. Proudly made in the USA, these Hastings piston rings offer the quality and reliability discerning riders demand for their Harley Davidson motorcycles.
