Mahle Rings 4.040in Bore .043in1/16in 3.00MM Plasma Moly Ductile Std Tension Reduced Moly Ring Set

Mahle is known for making solid OE replacement parts, and this piston ring set is no different. If you're rebuilding an engine and need a reliable set of rings for a 4.040-inch bore, these are a well-built option. They feature plasma moly ductile iron top rings, which are known for their good wear resistance and ability to handle the heat and stress inside a cylinder. The standard tension design works well in most stock and mildly modified applications.

This set includes rings with specific dimensions: the top ring is .043 inches, the second ring is 1/16 inch, and the oil ring is 3.00mm. This combination is common in many engine builds. The reduced moly coating on the top ring helps with initial seating and reduces friction, contributing to better performance and longevity. These rings are designed to fit right and perform as expected in your engine rebuild.
