MAHLE 3011198 Performance Gas Nitrided Piston Ring Set 4.185" Bore .043 .043 .157 RW

The MAHLE 3011198 performance piston ring set is engineered for high-performance applications requiring superior durability and reduced friction. Designed for 4.185-inch bore applications, this ring set features advanced gas nitrided steel construction in the top and second compression rings for exceptional wear resistance and strength under demanding conditions.

Key Features:

• 4.185-inch bore diameter for precision fitment
• Gas nitrided steel compression rings for enhanced durability and scuff resistance
• Ring widths: .043" top ring, .043" second ring, .157" oil ring (RW configuration)
• Low-friction design engineered to minimize drag and maximize horsepower
• Ultra-flat ring flanks for superior ring-to-piston sealing
• Designed using advanced ring simulation and computer modeling technology
• File-fit design allows for proper end gap adjustment

MAHLE's performance ring sets leverage decades of motorsports experience and OE engineering expertise. The gas nitriding process creates an extremely hard, wear-resistant surface on the steel rings while maintaining core strength and flexibility. This ring set is ideal for performance street engines, drag racing applications, and other demanding environments where reliability and power output are critical.
