Enhance the performance and longevity of your Harley Davidson Evolution 80" engine with this premium set of Hastings Piston Rings. Specifically designed as a +0.010 oversize replacement, these rings ensure optimal combustion sealing and oil control for a wide range of Harley Davidson models from 1983 to 2003.

Description

These Hastings +0.010 oversize piston rings are engineered to restore peak performance to your Harley Davidson Evolution 80" engine, covering models like the Electra Glide Classic FLHTC 1340 and Sportster XLH 1200 from 1983-2003. This comprehensive set includes top compression, second compression, and oil control rings, providing a complete solution for two pistons. The top compression rings feature a robust Barrel Face design with a cast coating, crucial for efficient heat transfer between the piston and cylinder wall. This design effectively controls combustion chamber gases, ensuring maximum energy transfer to the crankshaft for powerful and consistent engine output. The second compression rings are crafted with a Reverse Torsional Taper Face, promoting superior side sealing. This innovative design prevents oil from being forced under and behind the ring, significantly improving oil economy and reducing consumption. Its reverse twist and taper-machined face create an effective scraping edge, similar to a positive twist torsional ring. Finally, the Three Piece Flex Vent oil control rings offer exceptional conformability to the cylinder bore, thanks to their small cross-sectional area. With uniform pressure maintained by four steel rails and two expanders, these rings assure positive oil control, minimizing blow-by and contributing to a cleaner running engine. Proudly Made in the USA, Hastings piston rings deliver the quality and reliability discerning motorcycle enthusiasts demand for their Harley Davidson piston rings.
