The Speedmaster PCE306.1050 is a Plasma Moly piston ring set engineered for a 4.185-inch bore diameter with a 1.5mm / 1.5mm / 3mm ring groove configuration. The plasma moly coating reduces friction and promotes rapid ring seal, making this set a strong choice for high-performance and competition engine builds demanding durability and consistent cylinder pressure retention.
The zero-gap design provides a precision-fit solution ideal for builders who need tight tolerances right out of the box, minimizing blow-by and maximizing power output. Always verify bore diameter and ring groove dimensions against your specific engine application before installation to ensure proper fitment.
