What is a gapless top ring?

A gapless top ring has ends that meet when installed in the cylinder bore. This design eliminates any leakage past the top ring, which can improve compression and power compared to conventional rings with a gap.

What does the sizing 1/16", 3/16" refer to?

These measurements refer to the thickness of the top and second piston rings, respectively. This specific set features a 1/16 inch thick top ring and a 3/16 inch thick second ring, common dimensions for performance engine builds.

About this part

Product Details

When you're rebuilding the top end of your engine, the piston rings are critical for sealing the combustion chamber and managing oil. This Manley Performance gapless top ring set is designed for serious engine builds where precise sealing is paramount. The gapless design means the ring ends meet, preventing any blow-by past the top ring, which helps maintain consistent cylinder pressure and improved power output.

These rings are built with robust materials to handle the heat and stress of performance applications. The 1/16" top ring and 3/16" second ring dimensions are common for many performance engine builds, and the gapless top ring is a notable upgrade over standard designs. Proper installation is key to their performance; ensure your cylinder bores are perfectly honed and clean before fitting these rings to achieve the best seal and longevity.

This set is not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for detailed installation procedures and torque specifications.
