MAHLE 3011184 Performance Piston Ring Set - 4.115" Bore, .043" x .043" x 3.0mm, Gas Nitrided Steel

MAHLE 3011184 Performance Piston Ring Set

The MAHLE 3011184 is a high-performance piston ring set engineered for demanding applications where durability and reduced friction are critical. Designed for a 4.115-inch bore diameter, this ring set features an ultra-thin .043" (1.09mm) top ring, .043" second ring, and 3.0mm oil control ring configuration with reduced radial wall (RW) thickness for optimized performance.

Advanced Gas Nitrided Steel Construction

This ring set utilizes gas nitrided steel technology in the top ring, providing exceptional wear resistance and durability in high-stress applications. The gas nitriding process creates a hardened surface layer that resists scuffing and extends ring life, making it ideal for turbocharged, supercharged, and high-compression engines.

Performance-Oriented Design

The .043-inch (1.09mm) ring thickness represents MAHLE's modern low-tension design philosophy. Thinner rings reduce mass and inertia, allowing them to follow the cylinder wall more effectively while minimizing friction losses. The reduced radial wall construction further decreases tension load on the cylinder wall while maintaining superior sealing characteristics. This translates to measurable horsepower gains and improved engine efficiency.

Ring Configuration Details

• Top Ring: .043" gas nitrided steel with barrel face profile for optimal cylinder wall contact and combustion sealing
• Second Ring: .043" with taper hook groove design for superior oil control and groove side sealing
• Oil Ring: 3.0mm (3mm) standard tension oil control assembly for proper lubrication management

Key Features

• 4.115-inch bore diameter specification
• Gas nitrided steel construction for maximum durability
• Reduced radial wall (RW) design minimizes friction and ring tension
• File-fit design allows precision end gap adjustment
• Ultra-flat ring flanks maximize ring-to-piston sealing
• Engineered using MAHLE's advanced ring simulation technology
• Suitable for turbocharged, supercharged, and naturally aspirated performance builds

Applications

This ring set is designed for performance and racing applications where precise bore sizing and maximum durability are required. The 4.115" bore size is commonly found in large displacement V8 engines and performance engine builds. The gas nitrided steel material and reduced wall design make this set ideal for high-boost forced induction applications, nitrous oxide systems, and high-RPM naturally aspirated builds.

Set Contents

Each set includes rings for one cylinder. Multiply quantity by the number of cylinders in your engine (typically 4, 6, or 8) to ensure you order enough sets for your complete rebuild.

Note: These are file-fit rings requiring end gap adjustment during installation. Proper ring gap must be verified and filed to specification for your specific application before installation.
