Mahle MS 4.310in+ .005in 1/16in 1/16in 3/16in File Fit Rings

If you're rebuilding an engine and need to get the cylinders sealed up right, a good set of piston rings is crucial. This set from Mahle is designed for a file-fit installation, meaning you can precisely gap the end rings to match your specific engine's bore. This is a common practice when working with custom or performance builds where exact clearances are key to optimal performance and longevity.

These rings feature a 1/16 inch top ring, a 1/16 inch second ring, and a 3/16 inch oil ring. They are also specified as low tension and come at a +.005 inch oversize, which is important to note for your build. Mahle is a well-known name in engine components, and these rings are built to help you achieve a solid seal between your pistons and cylinder walls.

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 gapping recommendations.
