Product Details

The MAHLE 4150MS-15 is a high-performance piston ring set engineered for 4.145" bore engines with a +.005" tolerance. This file-fit ring set features a 1.5mm top ring, 1.5mm second ring, and 3.0mm oil ring configuration with standard tension for optimal sealing and durability.

Ring Configuration:

  • Top Ring: 1.5mm ductile iron with plasma moly coating and barrel face profile for superior wear resistance
  • Second Ring: 1.5mm cast iron reverse twist design for enhanced oil control
  • Oil Ring: 3.0mm three-piece standard tension assembly
  • File-fit ends allow precise end gap adjustment for your specific application

Performance Engineering:

  • Ultra-flat ring flanks maximize ring-to-piston groove sealing
  • Advanced piston ring simulation and computer modeling reduces friction
  • Plasma moly coating on top ring provides exceptional scuff resistance
  • Standard tension design balances sealing performance with ring longevity

MAHLE piston rings are precision-manufactured to reduce parasitic friction losses while maintaining excellent cylinder sealing. The file-fit design ensures proper end gap can be achieved for various bore conditions and applications, from street performance to professional racing.
