MAHLE 3030064 CP20 Low Tension Oil Ring Set - 3.8100" Bore 3mm Width Chrome

The MAHLE 3030064 is a precision-engineered CP20 low tension oil ring assembly designed for 3.8100-inch bore diameter engines. This three-piece oil control ring set features chrome-plated steel rails with a 3mm assembled edge width, delivering optimal oil control and cylinder wall sealing in performance and street applications.

Key Features:

• CP20 design with exclusive 20-degree ear angle for superior cylinder wall sealing
• Low tension configuration reduces friction while maintaining effective oil control
• Chrome-plated rails resist wear and provide long-lasting durability
• Three-piece assembly includes top rail, bottom rail, and expander/spacer
• 3mm (approximately 1/8") assembled width fits standard ring grooves
• Precision-engineered for 3.8100-inch cylinder bore diameter

MAHLE is one of the world's largest OE piston ring manufacturers, known for race-proven technology and rigorous testing standards. The CP20 oil ring design allows for proper oil drain-back while the expander locates the rails and controls ring tension. Chrome plating on the rail faces provides excellent wear resistance and long service life. Low tension design reduces parasitic friction losses while maintaining optimal oil control for performance engines.
