Upgrade your engine's performance with the HASTINGS 2C5232 piston ring set designed for 4.000-inch standard bore motors. This comprehensive set includes top compression rings, second compression rings, and oil control rings, ensuring optimal sealing and efficient operation. The top compression rings feature a barrel face coated with Physical Vapor Deposition (PVD), which enhances heat transfer from the piston to the cylinder wall, helping to reduce thermal stress and improve durability. These rings effectively control combustion gases, allowing the piston to transfer the energy generated during combustion to the crankshaft more efficiently. The second compression rings are Napier type with a reverse twist and taper-machined face, which work together to promote side sealing and prevent oil from entering the combustion chamber. This design contributes to cleaner operation and better oil economy. The oil control rings are a three-piece Flex Vent design, allowing for a small cross-sectional profile that conforms better to the bore for consistent oil regulation. The four steel rails and two expanders in this set distribute pressure evenly, providing reliable oil control and reducing oil consumption. Made in the USA, this piston ring set comes with enough rings for two pistons, with two rings per groove and two rail rings paired with one expander ring. Whether you're performing a rebuild or enhancing your engine’s efficiency, this set offers high-quality, durable components built to meet your engine's demanding standards. Proper installation ensures optimal performance and longevity, making the HASTINGS 2C5232 piston rings a reliable choice for your 4.000-inch bore engine. Designed for professional and enthusiast applications, these rings help maintain compression integrity, reduce oil consumption, and improve overall engine efficiency over the long term.
