Enhance your Harley Davidson’s engine performance and longevity with the Hastings 80″ Standard Piston Rings. This complete set is engineered for optimal combustion control and superior oil management, ensuring your motorcycle runs efficiently.
Description
The Hastings 80″ Standard Piston Rings are meticulously engineered to restore peak performance and extend the life of your Harley Davidson EVO 1340 or Sportster XLH 1200 engine from 1983-2003. This premium set includes all necessary rings for two pistons, designed to optimize critical engine functions. The top compression rings feature a robust barrel face design, crucial for efficient heat transfer between the piston and cylinder wall, while effectively sealing combustion chamber gases. This allows the piston to fully convert the energy of expanding combustion gases into crankshaft power.
Complementing these, the second compression rings utilize a reverse torsional taper face. This innovative design promotes superior side sealing, preventing oil from being forced under and behind the ring, leading to improved oil economy. The reverse twist, combined with a taper-machined ring face, effectively duplicates the scraping action of a positive twist torsional ring, further enhancing oil control. For ultimate oil management, the three-piece Flex Vent oil control rings are designed with a small cross-sectional area for exceptional conformability to the bore. They ensure uniform pressure through four steel rails and two expanders, providing positive oil control across a range of operating conditions. Proudly made in the USA, these Hastings 80″ Standard Piston Rings are a testament to quality and precision engineering for your Harley Davidson.
