Hastings 80" EVO Piston Rings 0.030" Oversize for HD FLHTC XLH

Get your Harley Davidson 80" EVO engine running optimally with Hastings 0.030" oversize piston rings. This complete set provides superior sealing and performance for a range of FLHTC and XLH models, ensuring your engine rebuild delivers reliable power and efficiency.

Description

These Hastings piston rings are meticulously engineered for the specific demands of Harley Davidson 80" Evolution engines, offering a 0.030" oversize for precise fitment during rebuilds. The comprehensive set includes top compression rings, second compression rings, and oil control rings, each designed with advanced features to maximize engine efficiency and longevity. The innovative barrel face top compression rings excel in heat transfer and combustion gas control, ensuring the piston effectively converts the energy of expanding combustion gases to the crankshaft. Second compression rings feature a reverse torsional taper face, promoting excellent side sealing that prevents oil from being forced under and behind the ring, significantly improving oil economy. For superior oil control, the three-piece Flex Vent oil rings utilize a unique design with small cross-sectional rails for better conformability to the cylinder bore and provide uniform pressure through four steel rails and two expanders, assuring positive oil scraping. Manufactured with pride in the USA, this kit provides a complete set of rings for two pistons, with two rings per groove (excluding the oil rails).
