Product Details

The MAHLE 40620 is a premium plasma-moly engine piston ring set engineered for 8-cylinder applications with a 3.875-inch bore. Ring thicknesses are 5/64 in. (top), 3/32 in. (second), and 3/16 in. (oil), sold as a complete set. MAHLE is one of the world's leading OE piston ring manufacturers, and this set reflects the same engineering standards found in original equipment applications.

Key Features:

  • SAE 9254 High-Alloy Steel Base Material — provides higher tensile and yield strength, extended fatigue resistance, and increased material hardness
  • Plasma-Moly Top Ring Coating — enhances cylinder wall compatibility, reduces friction, and promotes fast ring seating
  • Napier Second Ring Design — improves combustion gas management, supports top ring stability, and delivers superior oil control with minimal power loss
  • CP-20 Oil Control Ring — features an exclusive 20-degree ear angle for optimal side sealing in the piston oil ring groove and simplified installation
  • OE Form, Fit, and Function — engineered to meet or exceed original equipment specifications for reliable, long-lasting performance
  • Installer-Friendly Design — engineered for straightforward installation in professional or DIY engine rebuild environments
  • Complete Set — includes all rings needed for one 8-cylinder engine

MAHLE piston rings are driven by OE requirements focused on reducing friction and ring mass, minimizing engine oil consumption, and delivering extended service life. The MAHLE 40620 is the ideal choice for engine builders seeking a high-quality, technically advanced replacement ring set.
