Mahle MS 4.600in+ .005in 1/16in 1/16in 3/16in File Fit Rings

These Mahle MS piston rings are designed for a 4.600 inch bore and are file-fit, meaning you can precisely adjust the end gap to match your engine's specific needs. The rings feature a low tension design, which helps them seal better against the cylinder wall, especially in performance applications. This set includes the standard 1/16 inch thickness for the top and second rings, and a 3/16 inch thickness for the oil control ring.

Being file-fit gives you the flexibility to achieve optimal ring-to-piston clearance, a critical step for proper engine break-in and long-term performance. This is especially important when rebuilding or modifying an engine where precise tolerances are key. Mahle is a well-known name in engine components, and this set is built to their standards for reliable operation.

Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for specific installation instructions and recommended clearances.
