Product Details

Mahle is well-known for making solid engine components, and this set of MS 4.600-inch piston rings is no exception. These are drop-in rings, meaning they are designed to fit directly into your existing pistons without needing special machining, which can save you time and hassle during an engine rebuild. The ring set features a 1.5mm top ring, a 1.5mm second ring, and a 3.0mm oil ring, all with standard tension.

This configuration is a popular choice for many engine builds where a direct replacement is desired. The standard tension helps ensure a good seal against the cylinder wall, which is crucial for proper compression and oil control. While these rings are designed for a universal fit, it's always a good idea to double-check your piston groove dimensions to ensure they match the 1.5mm, 1.5mm, and 3.0mm specifications.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for detailed installation instructions and specifications.
