Product Details
Mahle is a well-known name in engine components, and this set of file-fit piston rings is a solid option for engine rebuilds. These rings are designed for a 4.610 inch bore with a +.005 inch oversize, and feature a specific ring groove sizing of .043 inches for the top and second rings, and 3.0mm for the oil ring.
Constructed from steel, these low-tension rings are built to provide a good seal against the cylinder wall. The 'file-fit' design means you'll need to file the end gap to achieve the precise clearance needed for your specific engine build, which is common when rebuilding engines for performance or custom applications. This allows for a more tailored fit compared to pre-gapped rings.
Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for proper installation procedures and ring gap specifications.
