Product Details

The MAHLE 4035MS-15 piston ring set is engineered for 4.030" bore applications with a +.005" oversize tolerance and file-fit design for precise end-gap adjustment. This standard tension ring set features 1.5mm, 1.5mm, and 3.0mm ring widths, optimized for high-performance engine builds requiring accurate ring sealing and minimal friction.

Ring Configuration:

  • Top ring: Ductile iron with plasma moly coating and barrel face profile for superior wear resistance and oil control
  • Second ring: Cast iron reverse twist design for enhanced compression sealing
  • Oil ring: 3-piece standard tension construction for optimal oil control

Key Features:

  • Ultra-flat ring flanks maximize ring-to-piston groove sealing
  • File-fit design allows custom end-gap fitting for precise engine tolerances
  • Advanced materials and coatings reduce friction for improved horsepower
  • Metric 1.5/1.5/3.0mm ring widths for modern performance applications

MAHLE pioneered piston ring simulation and computer-aided development to create rings that minimize friction losses while maintaining excellent sealing. This results in measurable power gains and improved engine efficiency, proven on both the dyno and the track.
