Product Details
Mahle is a well-known name in engine components, often recognized for their OE-quality parts. This set of Mahle MS file fit piston rings is designed for engine rebuilds where precise ring gap adjustment is needed. The rings measure 1.5mm for the top two compression rings and 3.0mm for the oil ring, with a standard tension profile.
These rings are a file-fit style, meaning you'll need to carefully file the end gap to achieve the correct clearance for your specific cylinder bore. This allows for a custom fit, which is crucial for optimal sealing and performance in a freshly bored or honed engine. The set is intended for a 4.000-inch bore and is +.005 inches oversized, designed to accommodate engines that have been machined to this specification.
Because these are file-fit rings, they require careful installation and measurement to ensure proper function. They are not CARB approved and cannot be shipped to California.
