Product Details
These Mahle piston rings are built with plasma-moly coated top rings, a tough material that stands up well to friction and heat. They're designed for a 4.600-inch bore, with a common ring size configuration of .043 inches for the top ring, .043 inches for the second ring, and 3/16 inches for the oil ring. This setup is a low-tension design, which helps reduce drag inside the cylinder for potentially improved efficiency.
Mahle uses ductile iron for the second ring, adding a bit more strength to that critical sealing surface. The plasma moly coating on the top rings is a popular choice because it helps them seat quickly and maintain a good seal against the cylinder wall, even under demanding conditions. This set is a solid option when you're rebuilding an engine and need reliable piston rings that fit right and perform well.
