SHIM (Mitsubishi MB12003-42311)

A shim that is too thin or worn can allow excessive clearance between mating components, leading to accelerated wear or noise. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB12003-42311. A shim is a thin, flat component used to fill gaps or adjust alignment between two surfaces. Its plain mechanical function is to take up space and maintain precise spacing under load. A common failure consequence is that a missing or incorrect shim can cause misalignment, resulting in premature component failure. During assembly, verifying the correct thickness is critical to proper function. Verify the serial number or application, then call (562) 693-7748.
