MAHLE 3011083B Performance Plasma Steel Top Ring Set 4.250in x 1.0mm HVOF Moly Bulk Pack

The MAHLE 3011083B is a performance plasma steel piston ring set designed for high-output racing and performance engines. Featuring a 4.250-inch bore size, 1.0mm top ring thickness, and a .143-inch radial wall width, this bulk ring set is engineered to deliver exceptional sealing performance under extreme operating conditions.

The top ring is manufactured from high-strength steel and finished with MAHLE's HVOF (High Velocity Oxygen Fuel) moly coating — a supersonic thermal spray process that delivers superior bonding strength, enhanced scuff resistance, and outstanding durability compared to conventional plasma coatings. This advanced face coating minimizes friction against the cylinder wall while maintaining a robust, long-lasting running surface.

Key Features:

• Bore Size: 4.250 inches
• Top Ring Thickness: 1.0mm (metric thin ring pack)
• Radial Wall Width: .143 inches
• Top Ring Material: Performance plasma steel
• Face Coating: HVOF (High Velocity Oxygen Fuel) moly
• Pack Type: Bulk — 48-quantity bulk pack for engine builders and race shops
• Superior bonding strength for increased ring durability
• Enhanced scuff resistance for high-load, high-RPM applications
• Reduced friction for measurable power gains

This bulk pack configuration makes the MAHLE 3011083B ideal for professional engine builders and race shops that require multiple ring sets for production builds. The thin 1.0mm ring pack reduces friction and reciprocating mass, contributing to improved power output and engine efficiency in performance and competition applications.
