MAHLE 3030830 Performance Oil Ring Assembly 4.120in x 2.0mm Low Tension Chrome Ring Set

The MAHLE 3030830 is a Performance Oil Ring Assembly designed for high-performance and racing engine builds. This three-piece oil control ring set is engineered for a 4.120-inch bore diameter with a 2.0mm ring width and a .113-inch radial wall (RW) thickness. The low tension design minimizes friction and parasitic power loss, making it well-suited for performance and competition applications.

Key Features:

• Bore Size: 4.120 inches
• Ring Width: 2.0mm
• Radial Wall Thickness: .113 inch
• Tension: Low tension for reduced friction and improved power output
• Face Coating: Chrome-faced steel rails for excellent wear resistance and durability
• Design: Three-piece oil ring assembly featuring two chrome-faced steel rails and an expander/spacer
• MAHLE CP-20™ expander design uses a 20-degree angle for superior side-seal and lower oil consumption versus conventional 90-degree tab designs

About MAHLE Performance Oil Rings:

MAHLE Performance oil ring assemblies are built to exacting tolerances for use in high-output naturally aspirated, turbocharged, and supercharged engine applications. All MAHLE Performance oil rings are of three-piece design, consisting of top and bottom steel rails and a center expander. The chrome-plated rail faces provide outstanding scuff resistance and longevity under demanding operating conditions. Low tension assemblies are ideal for performance builds where minimizing frictional losses is a priority without sacrificing oil control.

This ring set is sold as a single cylinder assembly (one oil ring set per cylinder). Order the quantity needed to complete your engine build.
