Engineered for optimal performance and durability, this kit provides a precise fit for a range of Harley Davidson models from 1978-1999, ensuring your engine runs efficiently with improved power transfer and oil control.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eExperience peak engine performance with Hastings Piston Rings, specifically designed for Harley Davidson 1340 engines. This comprehensive .040 oversize piston ring set is crucial for restoring lost compression and maintaining proper oil economy in your motorcycle. The top compression rings feature a barrel face design, optimizing heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases. This allows the piston to efficiently transfer the energy of expanding combustion gases to the crankshaft, enhancing overall engine output.\u003c\/p\u003e\n\u003cp\u003eThe second compression rings utilize a reverse torsional taper face, promoting superior side sealing to prevent oil from being forced under and behind the ring. This innovative design significantly improves oil economy and reduces consumption. The reverse twist ring, combined with a taper-machined face, creates a scraping edge that ensures better oil control. For the oil control rings, a three-piece Flex Vent design is employed. This construction allows for rails with a small cross-sectional area, offering better conformability to the bore and providing uniform pressure through four steel rails and two expanders for positive oil control. Proudly Made in the USA, Hastings Piston Rings deliver the quality and reliability motorcycle enthusiasts demand for their engine rebuilds.\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 control combustion gases, maximizing energy transfer to the crankshaft for improved power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Oil Economy:\u003c\/strong\u003e Reverse Torsional Taper Face second compression rings prevent oil bypass, reducing oil consumption and maintaining engine cleanliness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Bore Conformity:\u003c\/strong\u003e Three-piece Flex Vent oil control rings feature a small cross-sectional area for rails, ensuring better conformability to the cylinder bore and consistent oil scraping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive Oil Management:\u003c\/strong\u003e Uniform pressure from four steel rails and two expanders in the oil control rings guarantees effective oil control, critical for engine longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Engine Set:\u003c\/strong\u003e Includes all necessary top compression, second compression, and oil control rings for two pistons, providing a comprehensive solution for your rebuild.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Manufactured with high-quality standards in the United States, ensuring reliability and performance for your motorcycle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEngine Displacement: 1340cc\u003c\/li\u003e\n\u003cli\u003eOversize: .040\"\u003c\/li\u003e\n\u003cli\u003eTop Compression Ring Type: Barrel Face\u003c\/li\u003e\n\u003cli\u003eSecond Compression Ring Type: Reverse Torsional Taper Face\u003c\/li\u003e\n\u003cli\u003eOil Control Ring Type: Three Piece Flex Vent\u003c\/li\u003e\n\u003cli\u003eQuantity: Set for 2 Pistons\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: USA\u003c\/li\u003e\n\u003cli\u003eVehicle Fitment: Harley Davidson Electra Glide Classic FLHTC 1340, Softail Custom FXSTC 1340 (1978-1999)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 0075538114178\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.
