    OE Fit Replacement Caps. Manufactured to the high quality standards needed to match the factory parts, the components in the OPR Wheel Bearing Dust Cap 5-Pack are made to replace the caps in your 1979-1993 Mustang if they get damaged, go missing, or just begin to fit more loosely after many years or decades of use. These repair and restoration parts are made to provide the same tight fit as the originals, protecting the workings of your wheel bearings from dust, debris, liquids, and other contaminants.

    Precision Steel Build. These OPR Wheel Bearing Dust Caps are made from steel, like the originals, and are made to match them as exactly as possible – in design, size, fit, material, and performance. Their diameter is 1.78125 inches, or 1-25/32”, matching the OE specifications exactly. Fabricated from the same grade of metal and featuring a high polish, they include all the appropriate flanges and other shapings for excellent fitment.

    Protect Just Like the Originals. Rather than risking the degraded function that comes from wheel bearings that are gummed up with foreign matter – dust, dirt, etc. – installation of the OPR Wheel Bearing Dust Caps keeps your Mustang’s wheel bearings clean and pristine, just as was the case when the car rolled off the assembly line a generation ago. Installation of these parts, which include all the flanges and other attachment details of the original, spares you the trouble of constant wheel bearing maintenance or other inconvenience. This restoration part will return the wheel bearing assembly to its original function quickly and effectively, providing many years of exact-fit protection.

    OE Style Fitment. The OPR Wheel Bearing Dust Caps are made for quick, simple installation with precisely the same fit as the originals when new. The parts are made for a snug fit and may require some effort to snap them into place.

    Set of Five Bearing Covers. This set of OPR Wheel Bearing Dust Caps consists of (5) 1.78125” steel wheel bearing covers.

    Application. This 5 pack of OPR Wheel Bearing Dust Caps are a direct fit replacement for the 1979-1993 Mustangs including the LX, GT and SVT Cobra models. Equivalent to Ford part# B5A-1131-A.
