Description

The Mahle 4065MS-15-1 is a set of plasma moly piston rings designed for a 4.060" bore with a .005" over size, resulting in a 4.065" bore. These rings are file-fit, meaning they require precise gapping before installation. The set includes a 1.5mm ductile iron top ring with a plasma-moly facing, a 1.5mm cast iron second ring, and a 3mm stainless steel oil ring with standard tension.
