Your vehicle's differential is filled with fluid to keep the unit lubricated. The job of your Ford Thunderbird differential cover is to act as an oil pan to keep that fluid in place, but also allow you access to the internal components if they need replacement. While factory differential covers work just fine they are lacking in terms of style. Aftermarket Ford Thunderbird differential covers allow you to spruce up your undercarriage and are a sure way to impress people at the next show. Here at Andy's Auto Sport we have a great selection of Ford Thunderbird differential covers for you to choose from. Available in a range of styles and finishes from subtle to wild, you are sure to find the perfect unit to suit your taste in our large lineup.

While the main function of Ford Thunderbird differential covers is access and style, numerous aftermarket companies have developed high-performance diff covers that offer some innovative features. Some covers are built of extra-durable material to provide increased protection from rocks and debris, while other covers boast cast fins and added oil capacity to help cool down your differential fluid and internal components. If you plan on using and abusing your ride, we strongly recommend checking out some of these high-performance models.

Q: What is a differential cover? Why buy one?
A: Differential covers are the covers that mount on your differential to enclose and protect the internals of your differential (the ring and pinion gears), while still allowing you access to the inside so that you can make mechanical repairs when necessary. Differential covers are highly vulnerable to damage from rocks and debris on the ground which in turn can cause leaks. If you are in need of a replacement differential cover there are many options available. If you want to add some flash for a custom look, polished covers are available to make the underside of your ride glisten. If you have a vehicle that you take off road or on rough roads you may want a little added protection. If this is the case there are high-strength differential covers available made from extra thick material that essentially act as skid plates when used off road. When you mount one of these burly differential covers you can drive without fear of getting a puncture or leak in your differential cover. There are also finned differential covers available which will improve cooling and add longevity to the life of your differential. No matter what your requirements there is the perfect differential cover to fit your needs.
