Piston Ring

The Mahle File Fit Rings 4080MS-112-1 are a set of piston rings designed for custom fitting to cylinders. This set includes a top ring, second ring, and oil ring, all manufactured by Mahle Motorsports. The rings allow for control over the ring end gap, as they are typically oversized for precise fitting within the cylinder.

These rings feature a 4.080 inch bore size and are made from quality materials. The top ring is constructed of steel with an HV385 Thermal facing, while the second ring is also steel with a phosphate-coated facing. The oil ring is made of stainless steel with a chrome facing and standard tension. The set is sold as one complete unit for a single cylinder application.
