Upgrade your engine's performance with the HASTINGS 2C5231 piston rings designed for 3.937-inch standard bore engines. These high-quality rings are engineered to optimize heat transfer, improve sealing, and enhance oil control, ensuring smooth and efficient operation. The set includes top compression rings, second compression rings, and oil control rings, providing all essential components for a complete piston ring replacement.
HASTINGS piston rings feature a barrel face top compression ring coated using the advanced Physical Vapor Deposition (PVD) process. This coating enhances heat transfer between the piston and cylinder wall while reducing wear and extending the lifespan of the rings. The top ring effectively manages combustion gases, transferring energy to the crankshaft for optimal engine power. The second compression rings are Napier style with a reverse twist and taper-machined face, designed to promote side sealing and prevent oil leakage, which contributes to better oil economy and cleaner emissions.
The oil control rings are a three-piece flex vent design, allowing for a small cross-sectional profile that conforms well to the bore surface. These rails, combined with steel expanders, provide uniform pressure to ensure effective oil scraping and control, reducing oil consumption and preventing carbon buildup. Made in the USA, this set includes enough rings for two pistons, with two rings per groove (except for the rails, which include two rail rings per one expander ring). Designed for durability and precision, these piston rings are an excellent choice for restoring or upgrading your engine's performance.
