Product Details

The MAHLE 42246.030 is a +0.030" oversize moly piston ring set designed for Navistar MaxxForce 7 diesel engines (2011 and up), as well as select Ford 6.4L Power Stroke applications. MAHLE is one of the world's largest OE piston ring manufacturers, and this set is engineered to OE form, fit, and function standards for a direct replacement.

Built on an SAE 9254 high-alloy steel base material, these rings deliver higher tensile and yield strength, extended fatigue resistance, and increased material hardness compared to standard piston rings. The set includes a moly-faced top ring, a napier-style second ring for superior oil and combustion gas control, and MAHLE's CP-20 oil control ring featuring an exclusive 20-degree ear angle for optimum side seal in the oil ring groove.

Key Features:

  • +0.030" oversize bore — precision-sized for engines bored 0.030" over standard
  • SAE 9254 high-alloy steel construction — superior tensile strength, hardness, and fatigue resistance
  • Moly-faced top ring — reduces friction and improves scuff resistance for longer service life
  • Napier second ring — provides enhanced oil control, combustion gas management, and top ring stability
  • CP-20 oil control ring — exclusive 20-degree ear angle for best-in-class side seal and simplified installation
  • Pre-lapped rings — ensures precise fit and streamlines installation
  • OE form, fit, and function — engineered to meet or exceed original equipment specifications
  • Available in multiple sizes — standard, .010", .020", .030", and .040" oversize

MAHLE piston rings are developed using advanced piston ring simulation and computer design tools, reducing friction and ring mass while minimizing engine oil consumption for longer service life. This ring set is sold as a complete set covering all cylinders.

Nice and easy

Web site is very easy to follow or use. I'm thinking of finding other parts here. The battery has been delivered so quickly. It'd be better to see the order status changed from processing to shipping (or something) to know that it actually was shipped. But that's a small thing. I'll try other replacement parts here next time.

Good pricing on name brand products with easy at home shopping.
