Specifications
For dependable diesel rebuilding, the Mahle Clevite S41934 Engine Piston Ring Set delivers OE-equivalent sealing for Cummins M11/ISM engines. Piston rings must hold combustion pressure, transfer heat to the liner, and regulate oil film on every stroke. MAHLE ring technology uses high-alloy steel and advanced ring face designs to improve seating, reduce blow-by, and control oil without adding excess friction. Built for 125mm (4.921") bore cylinders, S41934 is a strong choice when restoring power, reducing smoke, and improving efficiency after overhaul. Sold by Wofford Truck Parts.
