MAHLE 3030792 Performance Oil Ring Assembly Bore Chrome Ring Set - 4.110 2.0mm

MAHLE 3030792 Performance Oil Ring Assembly

The MAHLE 3030792 is a high-performance oil ring assembly engineered for precision engine building applications requiring a 4.110-inch cylinder bore. This 2.0mm three-piece oil control ring assembly features standard tension design with chrome-plated rails for superior oil control and durability in high-performance and racing applications.

Key Specifications

• Bore Size: 4.110 inches
• Ring Width: 2.0mm assembled height
• Radial Width: 0.113 inches
• Tension: Standard tension
• Finish: Chrome-plated rails
• Design: Three-piece oil control ring assembly

Performance Features

MAHLE's performance oil ring assemblies utilize a three-piece design consisting of two chrome-plated steel rails and a precision expander. The chrome plating provides exceptional wear resistance and durability while maintaining proper oil control throughout the engine's operating range. The 0.113-inch radial width rails deliver effective scraping action to control oil consumption without excessive drag.

The standard tension expander is calibrated to provide optimal ring loading against the cylinder wall, ensuring consistent oil control while minimizing friction losses. This design promotes proper oil drainage back to the crankcase while maintaining a tight seal to prevent oil migration into the combustion chamber.

Applications

Designed for use in performance and racing engines with a 4.110-inch cylinder bore diameter. This oil ring assembly is commonly used in V8 engine rebuilds where precise oil control is critical for reliability and performance. The 2.0mm width makes it compatible with modern low-friction ring packs featuring 1.0mm-1.0mm-2.0mm or 1.2mm-1.2mm-2.0mm configurations.

Installation Notes

This is a universal performance oil ring assembly requiring proper installation technique. The expander must be installed first with ends butted together but not overlapped. Rails should be installed with gaps positioned 90-120 degrees from the expander ends to ensure proper function. Always verify ring end gap and that the assembly moves freely in the piston groove before installation.

Note: Designed for racing and off-road use. Sold as a complete oil ring assembly for one cylinder.
