A Direct-Fit Ford 9-inch Rear End Housing for Your 1968-74 X-Body

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 1968-74 GM X-Body Nova, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for stock X-Body rear ends. This X-Body 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 later 68-74 Chevy Nova rear end width and retains the stock shock mount locations as well. The axle’s leaf spring mounting brackets are welded in their stock mounting location and set up for a multileaf spring configuration for a bolt in solution. This allows you to retain stock ride height characteristics or you can lower the rear of your X-Body via lowering springs, shackles, or other options.

Includes Fully Assembled Axles Ready for Your Differential and Center Section

Our 68-74 Nova 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 4-3/4 GM 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 X-Body 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 68-74 X-body rear end build. Replace your tired 1968-1974 Chevy Nova rear end with our Ford 9-inch rear end in your Nova while maintaining the stock rear end width and upgrade to the strength and vast options the Ford 9-inch offers.

Overall Assessment

Customers highly appreciate our product for its quality and durability, particularly praising the stellar welding job on the 9-inch housing. Recognized for its cleanliness, the fitment of the third member and axles also received positive remarks for its perfect compatibility. Although a minor flaw was noticed with the placement of the drilled holes for the U-bracket, a customer confirmed this did not compromise the overall performance once corrected, further demonstrating the product's superior practicality and usability compared to others in the market.

for the most part everything was great but the holes they drilled for the U-bracket were almost in the side wall of the metal instead of in the bottom..honestly looked like someone was drunk when they drilled it because 2 holes where good and 2 where way off..had to redo the holes and then everything worked perfect.

I am definitely impressed!!
