The HASTINGS 2M4805005 piston rings are designed to deliver optimal engine performance for 96-inch Twin Cam engines. This set includes top compression rings, second compression rings, and oil control rings, providing comprehensive sealing and efficiency. The top compression rings feature a barrel face that enhances heat transfer between the piston and cylinder wall, helping to maintain proper operating temperatures and prevent overheating. These rings also control combustion gases, enabling effective transfer of energy from the expanding gases to the crankshaft, which improves power output and fuel efficiency. The second compression rings are Napier-style with a reverse twist and taper-machined face, mimicking positive twist torsional rings to promote side sealing. This design prevents oil from being forced under and behind the rings, contributing to better oil economy and cleaner combustion. The oil control rings are a durable three-piece flex vent design, which allows for a small cross-sectional profile that conforms well to the bore. This feature ensures uniform pressure distribution across the steel rails and expanders, delivering reliable oil control and reducing oil consumption. Crafted in the USA, these rings are made to exact specifications, with two rings per piston groove, excluding the rails which include two rail rings per one expander ring. The set is suitable for high-performance engines, providing durability and consistent sealing over extended use. Whether you're rebuilding or upgrading your engine, these piston rings are engineered to meet demanding standards and improve engine longevity. Proper installation and maintenance will maximize the benefits of these precision-engineered rings, ensuring your engine runs smoothly and efficiently for miles to come.
