A Direct-Fit Ford 9-inch Rear End Housing for Your Tri-Five Chevy 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 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 the famed 55-57 “Tri-Five” Chevy, Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for stock 55-57 Chevy rear ends. This housing is made from premium steel and is fully welded, including brand new “Torino” big Ford axle housing ends. The housing maintains the 55-57 Chevy car 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. This allows you to retain stock ride height characteristics or you can lower the rear of your Tri-Five Chevy via lowering springs, shackles, or other options.

Includes Fully Assembled Axles Ready for Your Differential and Center Section

Our 55-57 Tri-5 Chevy 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 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 Tri-Five Chevy 9-inch rear end build. Replace your tired 55-57 Chevy car rear end with our Ford 9-inch rear end in your 55-57 Chevy while maintaining the stock rear end width and upgrade to the strength and vast options the Ford 9-inch offers.
