Product Details

The Mahle 4030MS Performance Piston Ring Set is engineered for high-performance applications requiring precision sealing and reduced friction. This ring set evolved from Mahle's pioneering use of piston ring simulation and computer development tools to minimize friction and deliver "free" horsepower.

Key Specifications:

  • Bore Size: 4.030 inches (102.362mm)
  • Ring Thicknesses: 1/16" x 1/16" x 3/16"
  • Drop-in pre-gapped design for easy installation
  • Complete set for 8-cylinder applications

Advanced Ring Construction:

  • Ultra-flat ring flanks maximize ring-to-piston sealing
  • Top Ring: Plasma-moly coated ductile iron with barrel face profile
  • Second Ring: Reverse-twist cast iron taper face for oil control
  • Oil Control Ring: Standard tension 3-piece design with chrome-plated stainless steel rails

Performance Benefits:

  • Reduced friction for increased horsepower output
  • Superior sealing for improved compression
  • Enhanced oil control and reduced consumption
  • Excellent durability in high-performance and racing applications

Ideal for engine rebuilds in performance street, muscle car, and sportsman racing applications. These rings provide unmatched quality and ease of installation for rebuilders and technicians.
