MAHLE 42126CP Engine Piston Ring Set - Chrome/Plasma Moly

The MAHLE 42126CP is a complete engine piston ring set engineered to meet or exceed OEM specifications. MAHLE is a globally trusted supplier of engine components to both original equipment manufacturers and the professional aftermarket, bringing factory-quality standards to every ring set they produce.

This ring set features MAHLE's Chrome/Plasma Moly (CP) construction, which combines a durable chrome base with a plasma-applied molybdenum face coating on the top compression ring. This technology delivers superior wear resistance, excellent oil film retention, and faster break-in compared to standard chrome or cast iron rings.

Key Features:

• Chrome/Plasma Moly top ring for enhanced wear resistance and faster seating
• Complete ring set includes top compression ring, second compression ring, and oil control ring assembly
• Manufactured to tight OEM tolerances for consistent gap spacing and radial tension
• Superior oil film retention for reduced friction and improved engine longevity
• Compatible with both standard cast iron and aluminum cylinder bores (with proper preparation)
• Engineered for professional installation in engine rebuild applications

MAHLE piston ring sets are a preferred choice among professional engine builders for their consistent quality, precise fitment, and proven durability. The 42126CP is designed as a direct replacement during engine overhaul or rebuild, restoring proper compression and oil control to aging or worn engines.
