Upgrade your engine's performance with the HASTINGS piston rings designed specifically for 1340cc Big Twin motorcycles. These high-quality rings include top compression rings, second compression rings, and oil control rings, ensuring optimal sealing and efficient oil management. The top compression rings feature a barrel face with a cast coating that enhances heat transfer between the piston and cylinder wall, promoting consistent engine operation and preventing overheating. This design helps maintain proper combustion and transfer of energy from expanding gases to the crankshaft, contributing to improved power output and fuel efficiency.
The second compression rings are reverse torsional taper face rings that promote side sealing to prevent oil from leaking under and behind the ring. This design improves oil economy by reducing unnecessary oil consumption. The reverse twist combined with a taper-machined ring face mimics the bottom scraping edge of a positive twist torsional ring, enhancing sealing performance. The oil control rings are three-piece flex vent rings, engineered with a small cross-sectional area to improve bore conformity. These rings provide uniform pressure through four steel rails and two expanders, delivering superior oil control and minimizing oil consumption.
Manufactured in the USA, these piston rings are designed for durability and reliability. The kit includes enough rings for two pistons, with two rings per groove except for the rails, which are supplied with two rings per rail and one expander ring. These components are ideal for rebuilding or maintaining your Big Twin engine, ensuring long-lasting performance and efficient operation. Whether you're restoring a vintage motorcycle or enhancing a performance build, these Hastings piston rings deliver quality and precision for your engine's sealing needs.
