Piston Ring Set 4.375 Moly 1/16 1/16 3/16

The Piston Ring Set 4.375 Moly 1/16 1/16 3/16 from JE PISTONS is designed for high-performance and modified engines, where precise ring fitment is crucial for optimal compression and blow-by control. This set is ideal for enthusiasts who are rebuilding big-bore or stroker engines, addressing the transition between stock and heavily modified powerplants.

This piston ring set features moly-faced compression rings with a thickness of 1/16 inch for both the top and second rings, paired with a 3/16-inch oil control ring. The moly coating on the compression rings minimizes initial break-in friction and enhances scuff resistance under high-load and high-temperature conditions, making it suitable for turbocharged, supercharged, or nitrous oxide applications.

Engine builders and mechanics can rely on this piston ring set for performance builds, ensuring a proper fit for 4.375-inch bore diameter applications. It is essential for maintaining ring seal consistency and preventing excessive blow-by, especially in high-performance scenarios.
