A Direct-Fit Ford 9-inch Rear End Housing to Start Your Square Body C10 Build
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’s probably a safe bet there are more non-Ford vehicles on the road (and track) with a Ford 9-inch rear end under the rear of 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 the 1973-1987 C10 pickup, known to many by the “square body Chevy” moniker, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for the stock Chevy truck rear end. This housing is made from premium steel and is fully welded yet keeps the stock GM C10 axle housing ends, allowing you to use stock drum brakes or aftermarket disc options. The housing also maintains the 73-87 C10 rear end width for the 3rd generation Chevy pickup and retains the stock shock mount locations.
The axle’s leaf spring mounting pads are affixed in their stock “spring over axle” top mounting location. This allows you to retain stock ride height characteristics or you can lower the rear of your square body Chevy via lowering springs, shackles, or other options. We do offer our stock C10 flanged 9-inch Ford rear end housing with flipped leaf spring pad location as well if you’re looking to do an axle flip the right way to gain a 4-6 inch drop in the rear of your square body Chevy.
Includes Fully Assembled Axles Ready for Your Differential and Center Section
Our 9-inch Ford 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 the standard 1/2-ton truck 5 on 5 bolt pattern with 1/2-20 press-in threaded studs pre-installed as well. Finally, we include the axle retainer brackets and the correct 9-inch T-bolts and nuts to secure the axles and your original drum brake backing plates or disc brake kit of choice.
Additional hardware includes 10 press-in studs with nylon locking nuts for the main housing to center section assembly, and a screw in axle vent fitting that accepts a 5/16-inch hose. All your new 9-inch housing needs for completion is a complete center section with your choice of differential and gearing with your stock drum brakes or upgrade to our weld-on disc brake package. Our complete 9-inch 3rd members are the perfect choice to finish your 9-inch build to replace your tired Chevy truck rear end with our Ford 9-inch rear end in your square body Chevy while maintaining the stock 73-87 C10 rear end width.
