Piston Ring Set 4.065 Moly 1/16 1/16 3/16

The Piston Ring Set 4.065 Moly 1/16 1/16 3/16 from JE PISTONS is designed specifically for high-performance and modified engines with a 4.065-inch bore. This ring set is ideal for engine builders who require precision-fitted components for applications such as stroker builds or performance engine refreshes. It provides OEM-quality specifications that ensure reliable operation in various conditions.

Featuring moly-faced compression rings, this set offers superior scuff resistance and reduced friction losses, which are essential for maintaining performance under high cylinder pressures. The 1/16-inch top and second ring thickness, along with a 3/16-inch oil control ring thickness, create an optimal stack height that enhances blow-by control and skirt pressure across the RPM range. These features contribute to improved sealing and reduced oil consumption.

Engine builders and machine shops will benefit from the precision gap and ring thickness tolerances, which ensure compatibility with various piston groove dimensions. This ring set is suitable for both naturally aspirated and boosted applications, making it a versatile choice for serious DIY enthusiasts and professionals alike.
