MAHLE 42248CP.030 Engine Piston Ring - Set

The MAHLE 42248CP.030 is a precision-engineered engine piston ring set designed to meet or exceed original equipment (OE) specifications. MAHLE is a globally recognized OE supplier, and their piston rings are manufactured to the same exacting standards found in factory-built engines.

MAHLE piston rings are engineered to reduce friction and ring mass, helping to minimize engine oil consumption while delivering extended service life. Each ring set is produced using advanced materials and coatings developed through MAHLE's deep involvement with OE powertrain programs worldwide.

Key Features:

• OE-Quality Construction: Manufactured to original equipment standards for precise fit and reliable sealing
• Reduced Friction Design: Optimized ring geometry and surface finish minimize friction for improved efficiency
• Low Oil Consumption: Advanced ring profiles help control oil consumption and reduce emissions
• Extended Service Life: Premium materials and coatings resist wear for long-lasting performance
• .030" Oversize: Sized for engines that have been bored 0.030 inches over standard for a proper fit after cylinder machining
• Complete Ring Set: Includes all rings required for a full engine rebuild or ring replacement service

The 0.030" oversize designation means this set is intended for use in cylinders that have been bored or honed to 0.030" over the standard bore diameter. Always verify your cylinder bore measurement before selecting a ring set. MAHLE's piston ring technology is trusted by professional engine builders and OE manufacturers alike.
