Piston Ring Set 4.145 1/16 1/16 3/16

The Hastings Piston Ring Set 4.145 1/16 1/16 3/16 is a precision-engineered component designed for high-performance engine builds and rebuild applications where OEM or superior aftermarket ring sets are essential. This ring set addresses the critical function of sealing combustion pressure, controlling oil consumption, and maintaining proper blow-by levels—factors that directly impact engine efficiency, power output, and longevity.

Manufactured by Hastings, a trusted name in OEM and performance ring technology since 1921, this piston ring set features a 4.145-inch bore diameter sized to match common mid-sized and larger displacement engines across domestic and import platforms. The ring specification—1/16-inch top compression ring, 1/16-inch second compression ring, and 3/16-inch oil control ring—represents a balanced design that maximizes sealing effectiveness while minimizing friction and ring flutter at high RPM.

This ring set is ideal for engine builders, machine shops, and automotive enthusiasts looking to enhance engine performance. With its cast iron construction and precise groove tolerances, these rings are engineered to maintain consistent contact with the cylinder wall through thermal cycling and load variations, ensuring stable compression and minimal oil escape past the piston.
