About this part

Product Details

This is a Mahle file fit piston ring set, part number 4315MS. These rings are designed for engines where precise ring gap adjustment is needed during installation. The set includes standard tension rings with a 1/16 inch width for the top and second compression rings, and a 3/16 inch width for the oil control ring. This configuration is common in many performance and rebuild applications.

File fit rings offer a unique advantage because they allow you to precisely set the piston ring gap to match your specific engine build and bore size. This is crucial for optimal sealing, preventing blow-by, and ensuring proper oil control, especially in engines that have been bored out or modified. Mahle is a well-known name in engine components, and this set is built to meet the demands of a custom engine build. Remember that these rings are not CARB approved and cannot be shipped to California.
