MAHLE 42253CP Engine Piston Ring Set Chrome-Plasma Coated Standard Bore

The MAHLE 42253CP is a complete engine piston ring set engineered to OEM specifications for reliable performance and long service life. MAHLE is a globally recognized OEM supplier of engine components, and this ring set is manufactured to the same exacting tolerances as original equipment parts, ensuring a precise fit and proper seal in the cylinder bore.

The "CP" designation indicates a chrome-plasma (gas-nitrided or plasma-coated) ring finish, which provides superior wear resistance, reduced friction, and enhanced scuff resistance compared to standard cast iron rings. This coating is especially beneficial in high-heat or high-cycle engine applications.

Key Features:

• OEM-quality construction meeting or exceeding original equipment specifications
• Chrome-plasma (CP) coating for improved wear resistance and longevity
• Precision-ground ring profiles for optimal cylinder wall contact and sealing
• Complete set includes compression rings and oil control rings for all cylinders
• Manufactured to tight dimensional tolerances for proper end gap and side clearance
• Corrosion-resistant finish for extended durability

MAHLE piston ring sets are a trusted choice for engine builders, professional mechanics, and DIY enthusiasts performing engine rebuilds or overhauls. The MAHLE 42253CP delivers the reliability of OEM engineering in a direct-replacement package.
