MAHLE 3011124B Piston Ring Set 4.5675 Bore 1/16 x 1/16 x 3/16 Plasma Moly

The MAHLE 3011124B is a high-performance piston ring set designed for 4.5675-inch bore applications. This complete ring set features advanced materials and coatings engineered to deliver reduced friction, superior sealing, and extended service life in demanding engine builds.

Ring Configuration:

• Top compression ring: Steel construction with plasma-moly coating, .0625-inch (1/16") thickness, .190-inch radial width
• Second compression ring: Cast iron with reverse twist taper face design for enhanced groove side sealing
• Oil control ring: 3-piece standard tension assembly with .1875-inch (3/16") width

Key Features:

• Plasma-moly inlaid top ring provides excellent wear resistance and scuff protection
• Barrel-faced compression rings optimize contact area for efficient sealing and reduced blowby
• Pre-lapped ring surfaces seat quickly, virtually eliminating break-in time
• Ultra-flat ring flanks maximize ring-to-piston sealing
• Precision CNC-controlled gap chamfer optimizes compression characteristics
• Reverse twist second ring design ensures superior groove side sealing

Applications:

This bulk ring set is ideal for performance rebuilds and racing applications requiring precise bore sizes. MAHLE pioneered the use of computer simulation and development tools to engineer rings that minimize friction while maximizing durability and horsepower output. Ring materials, coatings, and tensions are optimized for high-performance engine applications where reliability and power are critical.
