Product Details
Mahle is well-known for its engine components, and this file-fit piston ring set is a solid option for engine rebuilds. This particular set is designed for a 4.530 inch bore and comes with a .005 inch oversize, meaning it's intended for engines that have been bored out slightly beyond their original specification. The ring groove dimensions are 1/16 inch for the top two rings and 3/16 inch for the oil ring.
These are low-tension rings, which can help reduce friction and improve oil control in certain applications. The 'file fit' designation means you'll need to gap the end rings yourself to ensure they fit perfectly within the cylinder bore. This is a common practice for performance builds or when precise tolerances are critical. Remember that these rings are not CARB approved and cannot be shipped to California.
