Mahle MS 4.060in+ .005in 1/16in 1/16in 3/16in File Fit Rings

This Mahle ring set includes all the components you need for a file-fit piston ring installation. You get a set of low-tension rings with specific dimensions: the top and second rings are 1/16 inch wide, and the oil control ring is 3/16 inch wide. These rings are designed for a 4.060 inch bore and are .005 inches oversize, meaning they're intended for engines that have been bored out to that specific dimension.

File-fit rings give you the flexibility to precisely set the end gap for your specific application, which is crucial for optimal engine performance and sealing. Mahle is a well-known name in engine components, and this set is built to meet the demands of engine rebuilding. The low-tension design helps reduce friction, contributing to improved efficiency.

Please note 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.
