Do you remember what it was like to scrounge salvage yards looking for a Ford nine-inch rear axle for your vintage Mustang? Most of the time you'd come home empty-handed or you were placed on a call list on the chance that the yard could find what you wanted. Or perhaps you were doing a six to V-8 conversion and had to search for the right nine-inch rear end, then had to settle for an eight-inch instead. Currie Enterprises has long understood your plight and has done something about it.
Founded in 1959, Currie Enterprises has always been about rear ends. If ever we could define the world's automotive rear axle expert, it would be Ray Currie and his handpicked team of professionals. What this means is exceptional quality from every Currie product. The company performs a lot of field-testing, both off-road and on-highway, to make sure it all works as advertised.

Currie nine-inch axle housings are made in America from raw materials.

Here, Currie cuts axle tubes to a predetermined length. Nothing goes to waste. Any scrap is recycled and used again.

Axle tubes are cleaned up for axle housing assembly. This makes it easy to fit tubes into the centersection.
For many years, Currie Enterprises had to work with available cores like the rest of us. In recent years, Currie has developed a rapport with U.S. suppliers and now offers complete Ford rear axle assemblies for a broad range of applications.
The Ford nine-inch rear end is legendary for its durability and simple design. Racers prefer the nine-inch, even those who compete in Chevrolet, Dodge, and other makes. Go to any NASCAR race or NHRA drag strip and look underneath the cars. You will see a Ford nine-inch beneath all kinds of rocket ships. There's simply no better performance rear end out there than the Ford nine-inch removable carrier.
For just under $1,100 plus taxes and shipping, Currie will build you a complete Ford nine-inch axle housing, including shafts, bearings, seals, plates, and hardware. Here's what you get for your money:

Here's the beginnings of what goes into a Currie crate axle. The centersection is available in either '57-'66 style with the rounded pot or '67-up with the bulge. As a rule, most look like this one. If you want the correct nine-inch housing for a '65 Mustang, you will need the rounded housing common prior to '67. If you're installing the rear in a '67 like us, you need this one. Currie centersections are manufactured by U.S. suppliers, so you're getting American quality and keeping Americans working.
When axle housings are assembled...
When axle housings are assembled and welded together, the nine-inch differential housing is torqued in place for the same reason we use torque plates when honing an engine block.

N-Case For Strength
Nodular iron, or "N-case," rear ends haven't been available from Ford in ages. Now Currie is offering the legendary Ford nine-inch N-case chunk for classic Mustangs and other vintage Fords in limited quantities. Just ask for part number CE-94027F, priced at $289.95 plus shipping. These are new nodular iron cases from Ford Racing Performance Parts that are identical to the originals, other than the lack of date codes and Ford casting numbers. They feature a 2.891-inch diameter bearing carrier for use with 28, 31, or 33-spline axles. These bulletproof cases include chrome moly carrier caps, bolts, spanner nuts, and spanner nut locks.

Normally a weak spot with eight- and some nine-inch carriers, this Currie pinion pilot bearing support has plenty of nodular iron for added strength.
