About this part

Product Details

These Mahle file-fit piston rings are precisely sized at 4.350 inches with a +.005 inch oversize. The ring groove dimensions are 1/16 inch for the top and second rings, and 3/16 inch for the oil ring, all featuring low tension design.

File-fit rings offer a unique advantage for engine builders who need to achieve a perfect seal in custom or performance applications. Because they are designed to be filed down to the exact piston groove clearance, they allow for a more precise fit than pre-sized rings. This attention to detail is crucial for optimizing compression and preventing blow-by, especially in engines that have been bored out or modified.

This set is not CARB approved and cannot be shipped to California. Always refer to your engine build specifications to ensure these rings are the correct choice for your application.
