Mahle MS 3.796in +.005in 1.0mm 1.0mm 2.0mm File Fit Rings

Mahle is well-known for making solid engine components, and these file fit piston rings are no exception. If you're rebuilding an engine and need to ensure a proper seal between your pistons and cylinder walls, these rings are a popular choice. They are designed to be filed to the exact gap needed for your specific application, which is crucial for optimal compression and oil control.

This set features a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. The file fit design means you'll need to carefully measure and file the end gap on the top and second rings to match your cylinder bore size. This allows for a more precise fit than standard pre-gapped rings, especially in custom or performance builds where exact tolerances are key. Mahle uses good materials to ensure these rings hold up under normal operating conditions.

Remember, these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for proper installation procedures and specifications.
