Product Details
If you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper sealing and performance. This Mahle MS file-fit ring set is designed for a 4.060 inch bore and comes with a +.005 inch oversize to ensure a precise fit during installation. The ring sizes are 1.0mm for the top and second rings, and 2.0mm for the oil ring, which are common dimensions for many performance and rebuild applications.
Mahle is a well-known name in engine components, and this set is built to meet the demands of an engine rebuild. The file-fit design means you'll need to gap the end of the top compression ring yourself to match your specific piston and cylinder wall clearance. This allows for a more custom fit compared to pre-gapped rings, which can be important for engines with modified components or specific performance goals. Remember that this set is not CARB approved and cannot be shipped to California.
