Fox Momentum For A Classic
Did you know you can purchase a late-model 8.8-inch integral-carrier rear axle and bolt it into your classic '65-'73 Mustang? Perhaps you are scratching your head, wondering why we would suggest the 8.8 for a vintage Mustang. Why not install the brute 9-inch beastie? The 8.8-inch Fox-body Mustang axle offers us as much strength as the 9-inch, with less internal friction and less weight. Drive Train Specialists can ship you this axle assembly, ready for bolt-in. All you have to do is pay for it, then tell them where to ship it. See Drive Train Specialists for more details.
Two Patches Of Rubber
You may upgrade your Ford rear axle with the installation of a Limited Slip clutch pack during a rebuild. This can be accomplished just as easily with a 71/4-inch integral-carrier axle as it can a 9-inch, four-pinion unit. Currie Enterprises, as one example, has Limited Slip differential kits for all types of Ford axles, including the 8.8-inch, Fox-body Mustang axle.
Check out the Currie Limited Slip, four-pinion differential hub (above). This close look at the Currie piece, alongside the Ford piece (at right), shows us how much better the Currie piece is. | 
The Currie steel piece is thicker, which makes it less prone to failure. | |
