A Direct-Fit Ford 9-inch Rear End Housing for Your Second Gen Camaro or Firebird
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 1970-1981 Camaro or Firebird, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for stock first gen F-Body rear ends. This Camaro 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 second gen Camaro or Firebird. The housing maintains the 2nd gen Camaro/Firebird 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 F-Body via lowering springs, shackles, or other options.
Includes Fully Assembled Axles Ready for Your Differential and Center Section
Our 2nd gen Camaro/Firebird 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 4-3/4 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 F-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 first gen F-body 9-inch rear end build. Replace your tired 67-69 Camaro/Firebird rear end with our Ford 9-inch rear end in your 67-69 F-body while maintaining the stock rear end width and upgrade to the strength and vast options the Ford 9-inch offers.
