Product Details
This is a Mahle piston ring set, specifically the 3910MS-112 model. These are file-fit rings, meaning they require careful measurement and gapping to ensure a precise fit within the cylinder bore. The set includes rings with thicknesses of 1.0mm for the top and second rings, and 2.0mm for the oil ring, all designed for a 3.905-inch bore with a .005-inch oversize allowance.
Mahle is a well-known name in engine components, and these rings are built to meet the demands of engine rebuilding. The file-fit design gives you the flexibility to achieve a perfect seal in your specific application, which is crucial for proper compression and oil control. This set is intended for universal applications where precise ring gapping is part of the engine build process.
