Description

Experience superior engine reliability and power with Hastings replacement piston rings, meticulously crafted for 80" Evolution (EVO) engines requiring a +0.020" oversize. This comprehensive set includes top compression rings, second compression rings, and oil control rings, all manufactured in the USA to stringent quality standards. The top compression rings feature a barrel face design, optimizing heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases to maximize energy transfer to the crankshaft. The second compression rings utilize a reverse torsional taper face, promoting superior side sealing to prevent oil from migrating under and behind the ring, leading to better oil economy and reduced emissions. Completing the set are the three-piece Flex Vent oil control rings, whose unique design with small cross-sectional area rails ensures exceptional conformability to the bore and uniform pressure for positive oil control. This complete set provides enough rings for two pistons, ensuring a thorough engine rebuild for your Harley Davidson motorcycle.
