Mahle Performance Piston Rings

MAHLE pioneered the use of piston ring simulation and computer development tools to engineer rings that provide free horsepower by successfully minimizing friction. MAHLEs ultra flat ring flanks and precision finish also maximize ring to piston sealing. The difference is evident on the dyno and the track. Mahle performance piston rings, developed with innovative computer simulation and development tools, include barrel-faced, plasma moly/ductile iron top rings, cast iron reverse-twist second ring, and conventional three-piece oil rings. Sets listed require file fitting.
