MAHLE 41724 Original Engine Piston Ring Set

The MAHLE 41724 is a premium OE-replacement engine piston ring set engineered to restore factory compression, minimize oil consumption, and extend engine service life. MAHLE is one of the largest OE piston ring manufacturers in the world, and this ring set is built to the same exacting standards as original equipment components — delivering proven form, fit, and function for a reliable engine rebuild.

Key Features:

• SAE 9254 High Alloy Steel Construction: Provides higher tensile and yield strength, extended fatigue resistance, and increased material hardness over standard ring materials
• Pre-Lapped for Fast Seating: Rings are pre-lapped at the factory to seat immediately, virtually eliminating traditional break-in time
• Optimized Ring Materials & Coatings: Ring tension, materials, and coatings are all tuned for reduced friction and extended service life in each specific application
• Barrel-Faced Compression Rings: CNC-controlled gap chamfer optimizes compression and reduces blow-by for maximum sealing efficiency
• Reverse Twist Intermediate Rings: Taper-race machined second rings provide better groove-side sealing and enhanced cylinder wall contact
• CP-20 Oil Ring Assemblies: Exclusive 20-degree ear angle delivers the best possible side seal against the cylinder wall; chemically polished oil ring expander enhances oil drain-back
• OE Form, Fit & Function: Designed as a direct replacement for original equipment piston rings — no modification required

MAHLE Original piston ring sets are the choice of professional engine builders for their ease of installation, consistent quality, and long-term durability. This set meets or exceeds OEM specifications, making it an ideal solution for engine overhaul or rebuild applications.
