MAHLE 41481 Engine Piston Ring Set OE Replacement

The MAHLE 41481 Engine Piston Ring Set is a premium OE-replacement ring set engineered to restore engine compression, minimize oil consumption, and reduce friction — meeting the same form, fit, and function standards as original equipment. MAHLE is one of the largest piston ring manufacturers in the world, with over a century of experience supplying both OE and aftermarket applications.

Key Features:

• SAE 9254 High Alloy Steel Base Material — delivers higher tensile and yield strength, extended fatigue resistance, and increased material hardness for long service life
• OE Form, Fit & Function — engineered to match original equipment specifications for a precise, reliable fit
• CP-20 Oil Ring Assembly — exclusive 20-degree ear angle provides superior side sealing in the piston oil ring groove and simplifies installation
• Napier Second Rings — high alloy steel napier design provides superior oil control, improved combustion gas management, top ring stability, and reduced power loss
• Pre-Lapped Rings — seat immediately upon installation, virtually eliminating extended break-in time
• Barrel-Faced Compression Ring Contact Area — promotes efficient compression seal and reduced blow-by
• CNC-Controlled Gap Chamfer — optimizes compression and minimizes combustion gas leakage
• Optimized Ring Tension — engineered for reduced friction and extended service life

MAHLE piston rings are the preferred choice for professional engine builders and rebuilders. This ring set is designed to minimize engine oil consumption, reduce internal friction, and provide a durable combustion seal — restoring engine performance to factory specifications.
