Product Details

The MAHLE 50009.040 is an OE-replacement engine piston ring set machined to a 0.040-inch oversize bore, designed for engine rebuilds requiring oversize pistons. MAHLE piston rings are among the most technically advanced in the industry, engineered to reduce friction and ring mass while minimizing engine oil consumption and providing longer service life.

Key Features:

  • Cast iron or ductile cast iron upper compression rings with a positive twist and barrel face for instantaneous break-in
  • Compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by
  • Second rings provide superior oil control, improved combustion gas management, top ring stability, and sealing for the best possible oil control and least power loss
  • Intermediate rings feature a reverse twist design for better groove side sealing and taper race machining to enhance contact
  • MAHLE CP-20 oil rings provide superior oil control utilizing the exclusive 20-degree ear angle for the best possible side seal in the piston oil ring groove
  • Designed to be installer-friendly and pre-lapped to seat immediately, virtually eliminating break-in time
  • High tensile strength, high yield strength, and excellent hardness with low ring mass — delivering stress resistance, minimal groove pound-out, long service life, cylinder conformability, oil economy, and good blow-by control with low friction

MAHLE is one of the largest OE piston ring manufacturers in the world and leads the industry for the latest piston ring technology. MAHLE replacement ring sets are designed with OE form, fit, and function, making the 50009.040 a trusted choice for professional engine rebuilders and performance enthusiasts alike.
