Product Details

The MAHLE 315-0032.040 is a plasma-moly ductile piston ring set engineered for serious performance engine builds. Sized for a 4.165-inch bore with a file-fit design, this set is sold as a complete 8-cylinder kit and delivers the precision sealing and low-friction performance that MAHLE is known for in racing and high-performance applications.

MAHLE pioneered the use of piston ring simulation and computer-aided development to produce rings that generate measurable power gains by minimizing friction losses. The ultra-flat ring flanks on this set maximize ring-to-piston groove sealing for optimal combustion efficiency and oil control.

Specifications:

  • Bore Size: 4.165 in. (File Fit)
  • Top Ring Thickness: 1/16 in.
  • Top Ring Material: Ductile Iron with Plasma-Moly Face Coating
  • Second Ring Thickness: 1/16 in.
  • Second Ring Material: Cast Iron
  • Oil Ring Thickness: 3/16 in.
  • Oil Ring Material: Stainless Steel
  • Oil Ring Tension: Standard
  • Cylinder Count: 8-Cylinder
  • Oversize: +0.040 in.
  • Quantity: Sold as a complete set (8 pistons)

The plasma-moly face coating on the top ring provides excellent scuff resistance and wear durability, making this set well-suited for high-output street performance and track use. The file-fit design allows builders to precisely dial in ring end gap for their specific application.
