Product Details
These Mahle file fit piston rings are designed for a 3.780 inch bore with an additional 0.005 inch clearance. The ring set features a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. File fit rings give you the flexibility to precisely set your ring gap during an engine rebuild, which is crucial for proper sealing and performance. This set is for a single cylinder, so you'll need to order enough sets for all the cylinders in your engine.
Mahle is a well-known name in engine components, and these rings are built to meet the demands of an engine rebuild. The file fit design means you'll need to carefully measure and file the ends of the top ring to achieve the correct gap for your specific engine's bore and intended use. This allows for a more custom fit compared to pre-gapped rings, helping to ensure optimal compression and oil control.
