Piston Ring Set 4.035 1.5 1.5 3.0mm

The MAHLE PISTONS Piston Ring Set 4.035 1.5 1.5 3.0mm (Part Number 4035MS-15) is a precision-engineered ring kit designed for high-performance eight-cylinder engine builds requiring exact bore dimensions and controlled compression sealing. This file-fit piston ring set delivers the controlled tension and material composition necessary for engines targeting consistent blowby control and ring longevity across varied operating conditions.

Built from ductile iron with plasma moly coating, these rings provide superior wear resistance and reduced friction compared to conventional cast iron rings. The 1.5mm top ring, 1.5mm second ring, and 3.0mm oil control ring configuration represents a modern compression package optimized for both street and competition applications. Plasma moly plating protects ring faces from scuffing during initial startup and prevents accelerated wear under sustained high-RPM operation.

This ring set serves engine builders, performance shops, and rebuilders preparing eight-cylinder mills for both street and circuit duty. Buyers installing this kit typically pair it with matching pistons and proper ring gap instrumentation to ensure optimal performance and longevity.
