Product Details
When you're rebuilding the top end of your engine and need a precise fit for your pistons, a good set of file-fit rings is essential. These Mahle MS rings are designed for a 4.060 inch bore, and they come in a 1.5mm, 1.5mm, and 3.0mm configuration, giving you the flexibility to achieve the exact gap needed for optimal sealing.
Mahle is a well-known name in engine components, and this set is built to perform.
