MAHLE 3011184B Performance Gas Nitrided Piston Ring Set Bore - 4.115

The MAHLE 3011184B is a high-performance gas nitrided steel piston ring set engineered for demanding automotive applications. This precision-manufactured ring set features a 4.115-inch bore diameter and is designed to deliver superior sealing, reduced friction, and enhanced durability in performance engine builds.

Key Features:

• Gas nitrided steel construction for exceptional wear resistance and extended service life
• 4.115-inch bore diameter for precise fitment
• 0.043-inch ring thickness specification
• 0.157-inch radial wall (RW) dimension ensures proper cylinder wall contact
• Plain ring design without coatings for specific performance applications
• Bulk packaging for professional engine builders and high-volume applications

MAHLE's gas nitriding process creates an ultra-hard surface layer that resists scuffing and wear while maintaining the steel's core strength and flexibility. This ring set is ideal for performance and racing engines where maximum durability and consistent ring seal are critical for maintaining compression and controlling oil consumption.
