A Direct-Fit Ford 9-inch Rear End Housing to Start Your OBS Chevy Pickup 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 9-inch Ford 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 1988-1998 GMT400 Chevy pickup, known to many by the “OBS” moniker (Old Body Style), Speedway Motors offers a bolt-in 9-inch Ford rear end housing for your build that is a direct swap for the stock C1500 Chevy truck rear end. This housing is made from premium steel and is fully welded, including brand new “Torino” big Ford axle housing ends. The housing maintains the 88-98 GMT400 Chevy truck rear end width for the 4th generation Chevy pickup and retains the stock shock mount locations for both two-wheel and four-wheel drive models.

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 OBS Chevy via lowering springs, shackles, or other options. We do offer our 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 GMT400 OBS 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 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 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 9-inch build to replace your tired GMT400 Chevy truck rear end with our Ford 9-inch rear end in your OBS Chevy while maintaining the stock 88-98 C1500 rear end width.

• 1988 to 1998 Chevy C1500
• 1988 to 1998 Chevy K1500
