What is a differential cover?

Differential covers serve a few different purposes. The primary purpose of a differential cover is sealing off the axle once the differential, gears, and axles have been installed. Differential covers can be made from several different materials. Most OEM Mustang covers are made from cast or stamped metals which can tend to break under higher loads of horsepower.

Cast aluminum vs Billet aluminum

Cast aluminum components are created by pouring molten aluminum into a mold. Once the molten aluminum solidifies, it can be removed from the mold and a raw cast aluminum part is made. Casting aluminum parts can be very labor intensive because of the time it takes to create molds, remove the casting from the mold and refine the final product.

Cast aluminum parts can be susceptible to breaking under intense loads if there are imperfections during the molding or refining processes.

Billet aluminum components are formed in a different manner than cast aluminum. To more thoroughly understand, I need to explain that “billet” is a solid piece of extruded material. In this case, I am talking about a solid piece of aluminum. A solid piece of aluminum can be used on a CNC machine to cut out high quality products without the need for expensive tooling and refinement processes.

While creating products from billet material isn’t ideal for mass production like casting is, billet products are usually much stronger and more refined. Now that you have all of that information, let me tell you about the product you’re here to learn more about!

The UPR Difference!

UPR Products has been heavily involved in the drag racing scene for many years. Usually, when you’re drag racing higher horsepower Mustangs, things tend to start breaking. UPR has always strived to provide the best quality parts with the racer in mind.

UPR’s Billet Differential Cover strengthens the rear end of your Mustang by adding more support for the differential bearing caps. This added support will allow the rear end to resist deflection under high loads of horsepower. It is made from 6061 Billet Aluminum and is available in two finish options: Satin Machined or Black Anodized.

Not only does UPR’s Billet Differential Cover strengthen your rear end, but it also looks good while doing so. UPR has integrated a fill and drain port to make adding or draining axle fluid a breeze.
