Mahle Rings 3.7795 X 1.5MM Chrome Steel Top Ring Chrome Ring Set

The top ring in this Mahle OE set is made from chrome steel, a material chosen for its strength and resistance to wear. This is important because the top piston ring is the one that takes the most heat and pressure, and it's responsible for sealing the combustion chamber. Mahle has been a well-known name in engine components for a long time, and this set is built to their OE standards.

This ring set is designed for a 3.7795 inch bore, and the top ring measures 1.5mm thick. The chrome plating on the top ring helps it break in smoothly and maintain a good seal against the cylinder wall over time. This is a solid option if you're rebuilding an engine and need reliable piston rings that fit right.
