The MAHLE 42192CP is a premium OE-replacement engine piston ring set engineered to deliver original equipment form, fit, and function. As one of the world's largest OE piston ring manufacturers, MAHLE brings factory-level precision to every ring set, making the 42192CP an ideal choice for engine rebuilds and overhaul applications.

Key Features:

• SAE 9254 High Alloy Steel Construction: Delivers higher tensile and yield strength, extended fatigue resistance, and increased material hardness for long-lasting durability
• Plasma-Moly Top Ring Facing: Provides superior cylinder wall sealing and accelerated break-in for reduced engine wear
• CP-20 Oil Ring Assemblies: Feature an exclusive 20-degree ear angle for optimal side sealing in the piston oil ring groove, simplifying installation and improving oil control
• Pre-Lapped Design: Rings are pre-lapped at the factory to seat immediately, virtually eliminating traditional break-in time
• Barrel-Faced Compression Rings: Optimize compression efficiency with a CNC-controlled gap chamfer that reduces blow-by
• Reverse Twist Intermediate Rings: Provide better groove side sealing with taper-race machining to enhance contact and reduce oil consumption
• Optimized Ring Tension: Engineered to reduce friction and ring mass while minimizing engine oil consumption and extending service life

MAHLE piston ring sets are designed to be installer-friendly, with pre-lapped surfaces, precision-ground gaps, and application-specific coatings and materials. The 42192CP meets or exceeds OE standards, making it a trusted solution for professional engine builders and experienced DIY mechanics alike.
