Piston Ring Set 4.030 TNT 1/16 1/16 3/16

The Piston Ring Set 4.030 TNT 1/16 1/16 3/16 by TOTAL SEAL is designed for serious engine builders and mechanics who require precision-fit rings for high-performance or rebuilt small-block applications. This set is specifically engineered to fit a 4.030-inch bore diameter, ensuring optimal compression sealing and blow-by control in custom engine builds.

Featuring the TNT profile, this ring set includes 1/16-inch top and second rings along with a 3/16-inch oil control ring. This configuration balances compression retention with minimal friction and effective oil management. Total Seal's proprietary design and premium materials provide consistent ring-to-wall contact, enhancing performance from cold starts to high-RPM operation.

Engine builders and mechanics working on small-block applications, including vintage muscle cars and modern race engines, will find this ring set invaluable when reboring or replacing damaged pistons at the 4.030-inch nominal size. The reliable performance and durability of Total Seal's TNT-profile rings make them a preferred choice for both professional and amateur engine builders.
