Engineered for durability and optimal engine function, this complete set provides superior sealing and heat transfer for a wide range of Harley Davidson models.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized Top Compression Rings:\u003c\/strong\u003e Barrel face and cast coating facilitate efficient heat transfer from the piston to the cylinder wall and precisely control combustion gases, maximizing engine power.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Second Compression Rings:\u003c\/strong\u003e Reverse torsional taper face design ensures superior side sealing, preventing oil bypass and significantly improving oil economy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced Oil Control System:\u003c\/strong\u003e Three-piece Flex Vent oil control rings feature a small cross-sectional area for excellent bore conformity, providing uniform pressure and positive oil control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Engine Set:\u003c\/strong\u003e Includes all necessary top, second, and oil control rings for two pistons, offering a comprehensive solution for your engine rebuild.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision Engineering:\u003c\/strong\u003e Designed with a reverse twist ring and taper-machined face for optimal scraping action and improved sealing performance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmerican Made Quality:\u003c\/strong\u003e Manufactured in the USA, ensuring high standards of craftsmanship and material durability for reliable long-term performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: Hastings\u003c\/li\u003e\n  \u003cli\u003eProduct Type: Piston Rings\u003c\/li\u003e\n  \u003cli\u003eEngine Displacement: 80 cubic inches\u003c\/li\u003e\n  \u003cli\u003eEngine Type: Evolution\u003c\/li\u003e\n  \u003cli\u003eBore Type: Standard\u003c\/li\u003e\n  \u003cli\u003eConfiguration: Complete set for two pistons (includes top, second, and oil control rings)\u003c\/li\u003e\n  \u003cli\u003eCountry of Origin: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 0075538112211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hastings","offers":[{"title":"Default Title","offer_id":63703171072330,"sku":"DS750640","price":16.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/8912d2cb60315d95cfdb84fd0c235ffa_ec2cd850-ccfe-4c4d-a0a9-722d15c43f39.webp?v=1790495196","url":"https:\/\/partsdenmark.com\/es\/products\/hastings-piston-rings-80-evolution-standard-for-harley-davidson","provider":"Parts Denmark","version":"1.0","type":"link"}
