Piston Ring Set 4.030 1/16 1/16 3.0mm

The Hastings Piston Ring Set 4.030 1/16 1/16 3.0mm is designed for engine builders and performance mechanics who are working on small-block platforms. This precision ring set is essential for restoring or enhancing compression, blowby control, and oil management in rebuilt or modified engines that require a 4.030-inch bore diameter.

Featuring a three-ring compression set, the Hastings Piston Ring Set includes a 1/16-inch top ring thickness, a 1/16-inch second ring thickness, and a 3.0mm oil control ring. This configuration is designed to optimize sealing geometry and gas-tightness across the combustion chamber, while the oil ring specification helps control oil scraping without excessive drag, which is important for fuel economy and longevity.

Engine builders and mechanics working with 4.030-inch bored engines will benefit from the Hastings Piston Ring Set's tight tolerances on ring gap, face profile, and material hardness. This ensures consistent performance across the engine's cylinders, reducing the risk of weak points that could compromise compression or increase emissions.
