Description
Piston rings are the critical seal between your pistons and cylinder walls—without proper ring quality, you’re losing compression, burning oil, and sacrificing horsepower. This 4.030″ ring set delivers plasma moly construction for extended durability and consistent blow-by control, whether you’re building a street engine or a weekend racer. File fit rings require honing to your specific bore, giving you the precision fit that factory-spec rings simply can’t match.
