Product Details

The MAHLE 42191 is a premium chrome piston ring set engineered for the Dodge/Chrysler 3.0L V6 diesel engine (OM642). Manufactured by MAHLE Original — a globally recognized leader in engine component technology — this ring set delivers OEM-grade sealing performance, reduced blow-by, and extended engine life.

Key Features:

  • Bore Size: 3.267 in. (standard bore) with ring thickness of 2.0mm / 2.0mm / 2.0mm
  • Chrome face coating on compression rings for superior wear resistance and long service life
  • Barrel-faced top compression rings for more efficient compression and rapid seating against the cylinder wall
  • CNC-controlled gap chamfer on compression rings to optimize compression and minimize blow-by
  • Reverse-twist intermediate rings for improved groove side sealing and taper race machining to enhance contact
  • CP-20 oil ring assemblies featuring an exclusive 20-degree ear angle for optimal side sealing against the cylinder wall
  • Special chemical polish on oil ring expander for enhanced oil drain back
  • Pre-lapped from the factory for immediate seating and virtually zero break-in time
  • Ring materials, coatings, and tension levels are application-optimized for reduced friction and maximum durability
  • Cross-references OEM part numbers: 6420300224 / 6420300024

MAHLE Original piston ring sets are the rings of choice for professional engine builders. Sold as a set covering one cylinder; a quantity of six sets is required for a complete V6 engine rebuild.
