Product Details
Mahle is well-known for their engine components, and these MS file-fit piston rings are a solid option for engine rebuilds. This set is designed for a 4.080 inch bore and includes rings with a 1.5mm top ring, a 1.5mm second ring, and a 3.0mm oil ring. The file-fit design means you'll need to gap the top ring yourself, which is common when building custom engines or working with non-standard bore sizes.
These rings are built with standard tension and are +.005 inches oversized, making them suitable for engines that have been bored out slightly. The file-fit nature allows for precise gapping to match your specific engine's needs, ensuring a good seal and optimal performance. Remember that these rings are not CARB approved and cannot be shipped to California.
