MAHLE 42288CP Engine Piston Ring Set

The MAHLE 42288CP Engine Piston Ring Set delivers OE-quality replacement performance with advanced materials and engineering. As one of the world's largest OE piston ring manufacturers, MAHLE designs ring sets that reduce friction and ring mass while minimizing oil consumption and extending service life.

Key Features:

• Constructed with SAE 9254 high alloy steel base material for superior tensile and yield strength
• Pre-lapped rings seat immediately, virtually eliminating break-in time
• Compression rings feature barrel-faced contact area for efficient compression and reduced blowby
• Second rings utilize reverse twist design for better groove side sealing
• CP-20 oil ring assembly with exclusive 20-degree ear angle for optimal side seal
• Premium coatings may include plasma-moly, chrome, or gas nitriding for wear resistance
• CNC-controlled gap chamfer optimizes compression performance

MAHLE piston rings incorporate race-proven technology engineered to meet demanding OE specifications. Ring materials, coatings, and tension are optimized for each application to deliver reduced friction, extended fatigue resistance, and increased material hardness for long-lasting performance.
