MAHLE 3011196 Performance Gas Nitrided Piston Ring Set Bore - 4.175

The MAHLE 3011196 is a high-performance piston ring set engineered for demanding applications requiring superior durability and sealing. This three-piece ring set is designed for a 4.175-inch bore diameter and features advanced gas nitrided steel construction for enhanced wear resistance and extended service life.

Key Features:

• Gas nitrided steel construction for maximum hardness and wear resistance
• 4.175-inch bore diameter for precise cylinder fitment
• 0.043-inch top ring thickness for optimal compression sealing
• 0.157-inch oil ring width for effective oil control
• Performance-grade design suitable for high-stress racing and modified engines
• Engineered to MAHLE's OE quality standards with aftermarket performance enhancement

This ring set provides the critical balance between compression sealing and oil control necessary for maximum horsepower and engine longevity. The gas nitriding process creates an extremely hard surface layer that resists scuffing during break-in and maintains ring seal under high cylinder pressures and temperatures. Ideal for performance rebuilds, racing applications, and heavy-duty engine builds where reliability is paramount.
