Product Details

The MAHLE Original 41786.030 is a plasma-moly piston ring set designed for V6 engines with a 4.030-inch (+0.030" overbore) cylinder bore. Built to OE form, fit, and function standards, this set delivers reliable sealing performance and long service life for engine rebuilds and overhauls.

Key Features:

  • Plasma-moly top ring (RF-13PF) — barrel-faced contact profile for efficient compression seal and reduced break-in time
  • SAE 9254 high-alloy steel base material — provides superior tensile and yield strength, extended fatigue resistance, and increased hardness
  • Pre-lapped rings — seat immediately upon installation, virtually eliminating traditional break-in requirements
  • Napier second ring (RBT-10) — reverse-twist design with taper-race machining for superior groove side sealing and improved combustion gas management
  • CP-20 oil control ring assembly — exclusive 20-degree ear angle delivers optimal side seal in the piston oil ring groove, with a chemically polished expander for enhanced oil drain-back
  • Ring thickness: Top — 5/64" (1.5mm) | Second — 5/64" (1.5mm) | Oil — 3/16" (3.0mm)
  • Bore size: 4.030 inches (102.362mm)
  • Optimized ring tension and coatings to minimize friction and reduce engine oil consumption
  • Sold as a complete set

MAHLE is one of the world's largest OE piston ring manufacturers, and the Original line is engineered to meet or exceed factory specifications. These rings are the choice of professional engine builders seeking installer-friendly components with proven durability.
