Hastings Piston Ring Set for Two Pistons

Upgrade your engine's performance and reliability with the Hastings Piston Ring Set. This comprehensive kit provides all the necessary motorcycle piston rings to restore optimal compression and oil control for two pistons, ensuring your motorcycle runs efficiently and powerfully.

Description

Designed for precision and durability, this Hastings Piston Ring Set is engineered to meet the demanding requirements of your motorcycle engine. Each set includes top compression rings, second compression rings, and oil control rings, providing a complete solution for an engine rebuild or performance upgrade. The top compression rings feature a Barrel Face design, crucial for efficient heat transfer between the piston and cylinder wall while effectively controlling combustion chamber gases. This design allows the piston to optimally transfer the energy of expanding combustion gases to the crankshaft, enhancing overall engine output.

The second compression rings are Napier-style, characterized by a reverse twist and a taper-machined ring face. This innovative design duplicates the scraping edge of a positive twist torsional ring, promoting superior side sealing. This action prevents oil from being forced under and behind the ring, leading to significantly better oil economy and reduced consumption. For precise lubrication management, the oil control rings are a Three Piece Flex Vent design. This three-piece construction allows for rails with a small cross-sectional area, ensuring excellent conformability to the cylinder bore. With uniform pressure provided by four steel rails and two expanders, these rings assure positive and consistent oil control, critical for engine longevity and performance. Proudly Made in the USA, this piston ring replacement kit includes enough rings for two pistons, making it a reliable choice for your engine's needs.
