The Speedmaster PCE306.1058 is a Plasma Moly piston ring set engineered for a 4.530-inch bore with a 1.5mm top ring, 1.5mm second ring, and 3mm oil ring configuration. The plasma moly coating on the top ring promotes faster break-in, reduces friction, and delivers improved wear resistance for high-performance and racing engine builds.
Featuring a Zero Gap design, this ring set is intended for performance applications where precise end-gap control is critical to maintaining compression and maximizing power output. Always verify bore size and ring groove dimensions against your specific engine build before installation.
