Description

Experience 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.

Features & Highlights

• Optimized Combustion Control: Barrel-face top compression rings efficiently transfer heat and seal combustion gases, converting expanding gas energy directly to the crankshaft for maximum power.
• Enhanced Oil Economy: Reverse torsional taper face second compression rings ensure superior side sealing, preventing oil bypass and significantly improving your engine's oil efficiency.
• Precision Oil Management: 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.
• Superior Bore Conformability: The unique three-piece design of the oil control rings allows for a smaller cross-sectional area, ensuring excellent adaptability to cylinder bore variations.
