Mahle MS 3.786in +.005in 1.0mm 1.0mm 2.0mm File Fit Rings

This is a Mahle MS piston ring set, specifically designed for universal engine applications. These rings measure 3.786 inches in diameter and are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. The set includes rings with a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring, all with standard tension.

Mahle is a well-known name in engine components, and this set is built to meet the demands of engine rebuilding. The file-fit design gives you the flexibility to achieve a precise fit in various bore sizes, which is crucial for proper sealing and compression. This is a solid option when you need reliable piston rings for a custom engine build or a rebuild where precise gapping is required.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and seating procedures.
