Knowing The Diffs

The rearend is often the last part of the drivetrain to be considered when building a car, and it usually receives attention only after something breaks. With good high-performance rearends available for Ford, GM and Mopar cars, there is no need for your ride to be sitting on a weak rear. In many cases, a stronger rear-axle assembly can simply be bolted in from the same make car. If you need something even stronger, you can swap from another make or model by finding one of the appropriate width and welding on the correct mounting pads. Or, if a Ford 9-inch is what you need, you can purchase a housing custom-remanufactured to fit your car by Currie Enterprises or Moser Engineering.

What we aim to do with this article is show you the variety of rearends available and how you can tell them apart.

So, if your rearend is currently making death noises or you would like to bypass that step in your car buildup, check out this gathering of high-performance housings and find one that meets your needs.
