Quarter Panel Extension is a body fitting on the Mazda that the exterior panels and trim depend on to stay located. Genuine Mazda part number b4ya7140x.
These parts are consumed rather than repaired: they break on removal, corrode, or lose their grip and let the panel they retain move. Match by part number — body hardware is dimension-critical and a 1 mm difference in shank or reach is enough to stop it seating.
Do not over-torque these fittings — the plastic or thin-gauge body panel strips before the fitting does.
Panels & Extensions Quarter Panel Extension replacement for Mazda. Cross-check the part number against the component you are removing before ordering.
