STDX Clearance: The "STDX" in the part number indicates an extra clearance bearing. This means the bearing is manufactured to provide a slightly larger oil clearance between the crankshaft journal and the bearing surface compared to a standard "STD" bearing. This is often desired in high-performance or racing applications to ensure adequate oil film at high RPMs and loads, or to accommodate crankshafts that are on the smaller side of the factory tolerance.
