Description

The Mahle 4065ML-043 is a set of low-tension piston rings designed for engines with a 4.060" bore, accommodating up to .005" oversize for a 4.065" bore. These rings feature a Plasma-Moly facing material on the top ring and a Ductile Iron top ring, with a Cast Iron second ring. The oil ring is constructed from Stainless Steel with low tension.

These piston rings are file-fit, meaning they require gapping to the specific cylinder bore during installation. Mahle Motorsport is recognized as a leading manufacturer in piston and ring technology, focusing on minimizing friction to achieve "free" horsepower.
