Product Details
Mahle is well-known for their engine components, and this set of file-fit piston rings continues that tradition. These rings are designed for engine rebuilding projects where precise fitment is key. The set includes three different ring sizes: two 1.5mm rings and one 3.0mm ring, all designed to be file-fit for a custom installation.
This particular set is specified as +.005" file fit, meaning you'll need to carefully file the end gap to achieve the correct clearance for your pistons and cylinder bores. This method allows for a more exact fit than standard pre-gapped rings, which can be beneficial for performance or high-mileage engine overhauls. It's important to note that these rings are not CARB approved and cannot be shipped to California.
