FORD 9-Inch Rear End Housing with Axles AND Center Section G Body

Frequently Asked Questions

Why is the Ford 9-inch rear end stronger than others?
The strength comes from its hypoid gear design, which creates more gear tooth contact—about 10% more than typical rears. Add in the ability to adjust the third member right on the bench, and you’ve got a setup that’s easier to dial in and holds up under serious power.

When was the Ford 9-inch originally produced?
Ford built the 9-inch from 1957 through 1986, using it across a wide range of cars and trucks. Its durability and ease of service are why it’s still a top choice decades later.

How is it different from a Ford 8.8-inch rear end?
The 9-inch uses a larger ring gear and features a drop-out third member. That makes it easier to swap gears or rebuild, especially for racing. The 8.8 is solid too, but the 9-inch is favored for track use because it’s stronger and more serviceable.

Can this rear end be narrowed for my build?
Yes. You can cut the housing and axles to your target width, then weld on suspension brackets to match your car. That’s especially common for custom or race builds where every inch counts.

Will this Ford 9-inch rear end fit my G-Body?
Yes, this rear end is designed to bolt into 1978 to 1988 GM G-Body vehicles like the Monte Carlo, Cutlass, Regal, Malibu, and El Camino.

What makes this rear end different from others?
This kit includes premium features at no extra charge like internal gussets, 3-inch .250 wall DOM tubes, and a fully assembled center section. Most competitors charge extra for these.

Can I choose my spline count and gear ratio?
Yes. We offer 28, 31, and 35 spline axle options and several gear ratios so you can match your performance needs.

Does this kit come with axles and the center section?
Yes. It includes a brand-new fabricated housing, axles, and a fully assembled center section based on your selected options.

Can the rear end be narrowed?
Yes. We offer free narrowing to fit your exact application. Just select your required length during checkout. If you need a length we don’t offer on the site please call.

What suspension mounting options are available?
The housing features options like billet aluminum coilover brackets, weld-on adjustable spring perches, and four or 11 hole lower control arm mounting holes.

Are brakes included in the kit?
Brakes are not included by default. We offer brake packages separately and can help you select the right setup for your build.

What finish does the housing come in?
The housing ships in bare steel. Powder coating is available as an upgrade for added protection and appearance.

Do I need to install bearings on the axles?
Yes. Bearings are included but not pre-installed. In many cases, your brake backing plates need to be installed first before pressing on the bearings.

How is the kit shipped?
Axles and the center section may ship separately from the housing and could arrive at different times. Crate-ready packaging and international shipping are available.

How can I identify a real Ford 9-inch housing?
Look for a drop-out third member at the front (no rear cover), nodular iron markings, and housing shape with center bands and sometimes dimples.

What’s the difference between a Ford 8.8 and 9-inch rear end?
The 9-inch has a larger ring gear, stronger pinion support, and removable center section, making it more durable and easier to service.

Why is the Ford 9-inch so popular for high-performance builds?
It offers superior strength with its large ring gear, two-bearing pinion support, and easy serviceability due to the drop-out center.

Which spline count should I choose?
Higher spline counts equal more strength. 31-spline is stronger than 28-spline, and 35-spline is ideal for serious horsepower builds. 40 spline would be for an all-out big power setup.

Can stock axles be shortened?
Most tapered 28-spline axles cannot be shortened. Some older 31-spline versions can be modified depending on the application. We do not offer this service in house but can set you up with a company that can.

What width options are available for the housing?
Standard widths vary by application. We offer custom narrowing to your exact spec for the best fit and tire clearance. Give us a call.

What’s the difference between sealed axle bearings and traditional ones?
Sealed bearings are internally lubricated and don’t require axle seals. They are easier to install and maintain.

What upgrades do you recommend for high-horsepower setups?
Popular upgrades include bigger spline axles, nodular iron or bolt through center sections, billet pinion supports, lockers, limited-slip, or spool diffs, and heavy-duty bearings.

How easy is it to change gears or swap the third member?
Very easy. The 9-inch uses a drop-out center section that removes with 10 bolts, making gear swaps quick and convenient for racers.
