Product Details
Mahle is well-known for making solid engine components, and this set of MS file-fit piston rings is no exception. If you're building or rebuilding an engine and need rings that offer a precise fit for your specific bore size, these are a strong option. The file-fit design means you can adjust the end gap yourself, which is crucial for achieving proper compression and oil control in custom or performance applications.
This set includes rings with a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. They are designed to be used in a 4.075 inch bore with an additional 0.005 inch clearance, giving you a bit of room to work with during installation. The standard tension is suitable for a wide range of engine builds. Remember that these rings are not CARB approved and cannot be shipped to California.
