Product Details

The MAHLE 42101CP Premium Piston Ring Set delivers OE-quality performance and reliability for your engine rebuild or repair. This complete ring set is engineered for 4-cylinder engines with a 3.464-inch (87.986mm) bore diameter and features a shallow groove design for optimal fitment.

Advanced Engineering and Materials: These piston rings are manufactured with precision-engineered materials including carbon steel top rings with chrome face coating for superior wear resistance, cast iron second rings, and stainless steel oil ring assemblies. The ring thicknesses are carefully optimized at 1.2mm (0.0468"), 1.5mm (0.0586"), and 2.5mm (0.0787") for the top, second, and oil rings respectively.

Installer-Friendly Design: MAHLE piston rings are pre-lapped to seat immediately, virtually eliminating break-in time and allowing for faster engine startup. The compression rings feature barrel-faced contact areas for more efficient compression and CNC-controlled gap chamfers to optimize compression while reducing blow-by. Intermediate rings utilize a reverse twist design for better groove side sealing with taper race machining to enhance contact.

Performance Features: The CP-20 oil ring assemblies feature an exclusive 20-degree ear angle design that provides superior side seal against the cylinder wall. Ring materials, coatings, and tension are all optimized to reduce friction and extend service life in demanding applications. This ensures reliable performance under high temperatures, elevated cylinder pressures, and high RPM operation.

What's Included: This is a complete set sold as 4 individual piston ring sets, providing everything needed for a 4-cylinder engine rebuild. Each set includes compression rings, intermediate rings, and oil ring assemblies.
