A Direct-Fit Ford 9-inch Rear End Housing for Your First Gen 67-70 Mustang
There 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 67-70 Mustang, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for stock first gen 67-70 Mustang rear ends. This Mustang rear end housing is made from premium steel and is fully welded, including brand new “Torino” big Ford axle housing ends. The housing maintains the 67-70 Mustang rear end width and retains the stock shock mount locations as well. The axle’s leaf spring mounting pads are welded in their stock mounting location for a bolt-in solution. This allows you to retain stock ride height characteristics or you can lower the rear of your Mustang via lowering springs, lowering blocks, or other options.
Includes Fully Assembled Axles Ready for Your Differential and Center Section
Our 67-70 Ford Mustang 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 Ford/Chevy 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 first gen 67-70 Mustang 9-inch rear end build. Replace your tired 67-70 Ford Mustang rear end with our Ford 9-inch rear end in your 67-70 Mustang while maintaining the stock rear end width and upgrade to the strength and vast options the Ford 9-inch offers.
Specs
- inside to inside of the brackets is 41"
- outside to outside on the brackets 45"
- center to center of the bracket 43"
- The axle flange to flange width of this rearend setup is the factory width of 59-1/4", the width of the housing itself is 54-1/4".

Everything about this kit is pretty nice. Welds are nice. Simple upgrade would be a drain plug. Does come with hardware for mounting the 3rd and the hardware/ back plate for the axle ends.

website suggest to buy the studs for the housing that i bought. The housing came with the studs. It was unclear if the product came with the studs or not and would be helpful to mention this. Maybe i missed this somewhere. The rear-end housing is great and i have no complaints about that.
Would Recommend
I think this rear housing and axles are 5 star.
