Piston Ring Set 4.155 Moly 5/64 5/64 3/16

The Piston Ring Set 4.155 Moly 5/64 5/64 3/16 is designed for engine builders and mechanics engaged in high-performance rebuild projects. This premium ring set is specifically engineered for 4.155-inch bore engines, serving as a direct replacement for worn or damaged original equipment. It is essential for anyone looking to restore displacement or maximize compression in modified powerplants.

The molybdenum coating on the top compression ring significantly reduces friction and enhances scuff resistance during initial startup. The ring design features a 5/64-inch top compression ring, a 5/64-inch second ring, and a 3/16-inch oil ring, which effectively balances blow-by control with oil management across various RPM ranges. This ensures a precision fit and sealing integrity that is crucial for high-performance applications.

This piston ring set is particularly beneficial for those rebuilding small-block engines or engaging in mild competition builds. It allows for optimal ring gap clearances in custom applications, ensuring proper gap closure without binding. By minimizing blow-by and preserving ring life, this product is a valuable asset for serious engine builders.
