MAHLE 3011162 Performance Gas Nitride Steel Piston Ring Set Bore - 4.005

MAHLE 3011162 is a high-performance gas nitride steel piston ring set engineered for demanding performance applications. This precision-manufactured ring set features a 4.005" bore diameter with .043" (1.09mm) top and second compression rings, paired with a .157" (4.0mm) reduced width (RW) oil control ring.

Key Specifications:

• Bore Size: 4.005 inches
• Top Ring Thickness: .043" (1.09mm) - Gas Nitride Steel
• Second Ring Thickness: .043" (1.09mm)
• Oil Ring Width: .157" (4.0mm) Reduced Width
• Plain Ring Set (File-to-Fit)

Performance Features:

• Gas nitride treatment provides exceptional overall strength and toughness comparable to PVD and DLC coatings
• High tensile strength allows the piston rings to stand up to extreme firing pressures
• MAHLE pioneered the use of piston ring simulation and computer development tools to engineer rings that provide "free" horsepower by successfully minimizing friction
• Ultra flat ring flanks and precision finish maximize ring to piston sealing
• Reduced width oil control ring for improved oil management and reduced drag

The .043" ring sets feature a taper hook groove design in most popular bore sizes, providing superior oil control and combustion gas management. This plain ring set requires file-fitting to achieve proper end gap specifications for your specific engine build. MAHLE Performance piston rings exceed the ever increasing demands of todays advanced performance engines and are trusted by professional engine builders and racers worldwide.
