Mahle Rings 4.060in Bore .043in 3/16in Plasma Moly Duct Std Tension Reduced Radial Moly Ring Set

If you're rebuilding the engine in your classic muscle car or a performance build, getting the right piston rings is crucial for sealing and compression. This Mahle OE ring set is designed for a 4.060-inch bore, a common size for many V8 engines.

These rings feature a plasma moly ductile iron construction, which is known for its strength and wear resistance. The top ring is 0.043 inches thick, and the oil ring is 3/16 inches, fitting standard piston groove dimensions. They also have reduced radial tension and a moly coating, helping them seat quickly and maintain a good seal against the cylinder wall, which is important for both power and oil control.

This set is a solid option for many engine rebuilds where a reliable, well-built piston ring is needed. Keep in mind that these rings are not CARB approved and cannot be shipped to California.
