Return PolicyThere is certainly no denying the popularity of Ford’s venerable 9-inch rear axle when it comes to high performance street and racing applications. It is probably a safe bet there are more non-Ford vehicles on the road (and track) with a Ford 9-inch rear end under them than Ford ever shipped off their assembly lines! That is saying a lot right there. From the stronger housing design to the huge aftermarket support in axles, differentials, ring and pinion gears, and more, the Ford 9-inch rear end is the performance axle housing to use, without a doubt.
For those building up a 79-93 Fox Mustang, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for stock Fox body Mustang rear ends. This Fox Mustang rear end housing is made from premium steel and is fully welded, including brand new “Torino” big Ford axle housing ends and features a durable gloss black powder coat for long term protection and great looks under your Foxbody Mustang. The housing maintains the 79-93 Fox body rear end width and retains the stock shock mount locations as well. The axle’s upper and lower control arm mounting brackets are welded in their stock mounting locations for a bolt-in solution. This allows you to retain stock ride height characteristics or you can lower the rear of your Mustang via rear coilovers or other options.
Our 79-93 Foxbody 9-inch rear end housing package includes strong 31-spline performance axles with bearings and bearing lock rings already pressed into place on the axles. The axles feature dual Chevy/Ford bolt pattern of 5 on 4-3/4 and of 5 on 4-1/2 with 1/2-20 press-in threaded studs preinstalled in the 5 on 4-1/2 Ford pattern. Finally, we include the axle retainer brackets and the correct 9-inch T-bolts and nuts to secure the axles and your drum or disc brake kit of choice.
Additional hardware includes 10 press-in studs with nylon locking nuts for the main 9-inch housing to center section assembly, and a screw in axle vent fitting. All your new Ford 9-inch housing needs for completion is a complete center section with your choice of differential and gearing and drum or disc brake package. Our complete 9-inch 3rd members are the perfect choice to finish your third gen Fox Mustang 9-inch rear end build. Replace your tired 79-93 Ford Mustang Fox body rear end with our Ford 9-inch rear end in your Foxbody Mustang while maintaining the stock rear end width and upgrade to the strength and vast options the Ford 9-inch offers.
