This comprehensive set provides everything needed for a complete engine rebuild, ensuring optimal performance and longevity for your motorcycle. Designed for 80 cubic inch Evolution engines, these oversize piston rings are crucial for restoring compression and oil control.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eExperience superior engine performance with these high-quality Hastings Piston Rings. Specifically designed for 80 cubic inch Harley Davidson Evolution engines requiring a +.005\" oversize, this set includes top compression rings, second compression rings, and oil control rings. Each component is engineered to enhance your engine's efficiency and durability. The top compression rings feature a barrel face design, crucial for effective heat transfer between the piston and cylinder wall, while also controlling combustion gases to maximize power delivery to the crankshaft. The second compression rings utilize a reverse torsional taper face, promoting excellent side sealing to prevent oil from being forced past the ring, leading to improved oil economy. This unique design effectively scrapes oil from the cylinder wall. Finally, the three-piece Flex Vent oil control rings offer superior conformability to the bore, ensuring uniform pressure and positive oil control through their robust steel rails and expanders. Proudly Made in the USA, Hastings piston rings are a testament to quality craftsmanship and engineering excellence, perfect for a reliable Harley Davidson engine rebuild.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Combustion Control:\u003c\/strong\u003e Barrel-face top compression rings efficiently transfer heat and seal combustion gases, converting expanding gas energy directly to the crankshaft for maximum power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Oil Economy:\u003c\/strong\u003e Reverse torsional taper face second compression rings ensure superior side sealing, preventing oil bypass and significantly improving your engine's oil efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Oil Management:\u003c\/strong\u003e Three-piece Flex Vent oil control rings with steel rails and expanders provide uniform bore pressure for consistent and positive oil control, reducing consumption and emissions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Bore Conformability:\u003c\/strong\u003e The unique three-piece design of the oil control rings allows for a smaller cross-sectional area, ensuring excellent adaptability to cylinder bore variations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Engine Rebuild Solution:\u003c\/strong\u003e Includes a full set of top, second, and oil control rings for two pistons, providing a comprehensive solution for your engine's needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmerican Made Quality:\u003c\/strong\u003e Manufactured in the USA, guaranteeing high-quality materials and precision engineering for reliable and long-lasting performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Hastings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 80\" Evolution (EVO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize:\u003c\/strong\u003e +.005\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Set Type:\u003c\/strong\u003e Replacement Piston Rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Top compression rings, second compression rings, oil control rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Ring Design:\u003c\/strong\u003e Barrel Face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecond Ring Design:\u003c\/strong\u003e Reverse Torsional Taper Face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Control Ring Design:\u003c\/strong\u003e Three Piece Flex Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Harley Davidson Electra Glide Classic FLHTC 1340, Sportster XLH 1200 (1983-2003)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 0075538112341\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to Know\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSpecial attention is required for the top ring end gap, especially with KB pistons, due to their thermal conductivity and design.
