Product Details

The MAHLE 41718.040 is a premium-grade engine piston ring set designed for the 6.5L diesel V8, featuring a +0.040" oversize bore diameter of 4.095". Engineered to OE form, fit, and function, this set is built on a SAE 9254 high-alloy steel base material for superior tensile and yield strength, extended fatigue resistance, and increased material hardness.

Key Features:

  • Plasma-Moly top ring coating on ductile iron compression rings for maximum wear resistance and reduced friction
  • Barrel-faced contact area on compression rings for more efficient sealing and CNC-controlled gap chamfer to minimize blow-by
  • Reverse twist intermediate rings with taper race machining for superior groove-side sealing and enhanced cylinder wall contact
  • CP-20 oil ring assembly with exclusive 20-degree ear angle for optimal side sealing against the cylinder wall and simplified installation
  • Special chemical polish on the oil ring expander for enhanced oil drain-back performance
  • Pre-lapped from the factory for immediate seating, virtually eliminating break-in time
  • Ring tension optimized per application to reduce friction and extend service life

Ring Specifications:

  • Top Ring (UCR): Ductile Iron | Plasma-Moly Facing | 3.0mm Axial Height | Type: RFK-18PF
  • Second Ring (LCR): Ductile Iron | 2.0mm Axial Height | Type: BT-18
  • Oil Ring Assembly (OCR): Cast Iron | Chrome Facing | 4.0mm Axial Height | 2-Piece | Type: MCL-40URW
  • Bore Diameter: 4.095" (+0.040" Oversize)
