Mahle Rings 4.040in Bore .043in 3/16in Plasma Moly Duct Std Tension Reduced Radial Moly Ring Set

This Mahle OE Piston Ring Set includes the rings needed to rebuild one piston, featuring a 4.040 inch bore size. The top ring is .043 inches thick, and the oil ring is 3/16 inches. These rings are designed with plasma moly for durability and reduced radial tension for better sealing.

Mahle has been a trusted name in engine components for a long time, and this ring set is built to meet those standards. The plasma moly coating on the top ring helps it resist wear and maintain a good seal against the cylinder wall, even under demanding conditions. The reduced radial tension design helps the rings conform better to the cylinder bore, which can lead to improved oil control and compression sealing. This set is a solid option when you're rebuilding an engine and need reliable piston rings.
