Piston Ring Set 4.155 1/16 1/16 1/8

The Sealed Power Piston Ring Set 4.155 1/16 1/16 1/8 is designed for engine builders and mechanics who require reliable compression sealing in both high-performance and stock rebuild applications. This precision ring set is essential for maintaining critical compression in the combustion chamber while effectively controlling oil consumption, which is vital for consistent power delivery and engine longevity.

Constructed with premium materials and precise tolerances, the 4.155-inch bore diameter rings feature a 1/16-inch compression ring thickness along with a 1/8-inch oil ring thickness. This proven geometry balances sealing pressure with minimal friction. The two compression rings work together to contain peak combustion pressures, while the oil ring prevents excess lubrication from entering the combustion chamber, thus preserving fuel economy and emission performance.

This ring set is ideal for rebuilding 4.155-inch bore engines, which are common in many small-block and mid-displacement applications. It is a go-to choice for engine overhauls, performance builds, and restoration work, making it a trusted option for both professional shops and serious automotive enthusiasts.
