Mahle Rings Plasma Moly Steel 1.5MM x .151 RW 4.100in Bore Diameter Moly Ring Set

This Mahle OE piston ring set includes all the rings needed for one engine, designed for a 4.100 inch bore diameter. These rings feature plasma moly steel construction, a well-known material for its strength and wear resistance in demanding engine environments. The 1.5mm top ring and .151 inch second ring are specifically sized to work with pistons designed for this bore size, helping to ensure a proper seal between the piston and cylinder wall.

Mahle has been a trusted name in engine components for a long time, and this ring set reflects that experience. The plasma moly coating on the top ring is a practical detail that helps reduce friction and wear, which can lead to a longer ring life and more consistent engine performance over time. When you're rebuilding an engine, getting the piston rings right is crucial for compression and oil control, and this set is built to meet those needs.
