Upgrade your engine with the HASTINGS piston rings designed specifically for Twin Cam 96 motorcycles. These high-quality rings include top compression rings, second compression rings, and oil control rings, all engineered to optimize engine performance and longevity. The top compression rings feature a barrel face that aids in heat transfer between the piston and cylinder wall, helping to maintain optimal operating temperature and prevent overheating. They also control combustion gases, ensuring efficient energy transfer from the expanding gases to the crankshaft for smooth power delivery. The second compression rings are Napier type with a reverse twist, paired with a taper-machined ring face that duplicates the bottom scraping edge of a positive twist torsional ring. This design promotes side sealing to prevent oil from leaking under and behind the rings, resulting in improved oil economy and reduced emissions. The oil control rings are a three-piece flex vent design, allowing for better conformability to the bore with a small cross-sectional area. This configuration ensures uniform pressure distribution through four steel rails and two expanders, providing effective oil control and reducing oil consumption. Made in the USA, these rings come with enough components for two pistons, with two rings per groove (except for the rails, which include two rail rings per one expander ring). Whether you're rebuilding or enhancing your Twin Cam engine, these Hastings piston rings offer reliable performance with precise fit and durability. Proper installation of these rings will help maintain engine efficiency, reduce wear, and extend the lifespan of your motorcycle engine.
