PRI 2025: Moser Engineering Debuts Stamped 9-Inch Housings

For Ford enthusiasts pushing their vehicles to the limit, the inevitable weak link is often the differential. At the 2025 PRI Show, Moser Engineering presented a solution with their new lineup of stamped 9-inch housings. Designed to accommodate everything from street restorations to high-horsepower drag builds, these housings maintain the proven geometry of the classic design while offering three distinct levels of strength.

Moser’s approach allows builders to match the durability of the housing to the specific application. “With the Standard Duty 9-inch, everything is stamped here in the U.S. We basically have a 9-inch Standard Duty that’s standard for a 3-inch tube with a 3/16- or 1/4-inch wall, and that’s our standard line,” said Jeff Anderson, marketing director at Moser Engineering. “It’s available in a notchback, or a round back, and then we step up to the Heavy Duty stamped 9-inch, which allows a 3-inch tube, as well, and it’s kind of reminiscent of what you imagine when you think of a 9-inch Heavy Duty coming out of the truck back in the day.”

The Standard Duty 9-inch housings are perfect for street performance, providing a solid foundation for standard axle and gear combinations. For those running stickier tires or higher horsepower, the Heavy Duty option increases material thickness. However, for the most intense setups, Moser offers the Extreme Duty line. “For our severe-duty applications, the Extreme Duty 9-inch, it’s a 1/4-inch-thick steel, relaxed radius, and it’s set up to work with all the heaviest-duty applications, so if it’s a big performance vehicle, it’s set up where I can actually work with a 3- or a 3 1/4-inch tube so you can go to a bigger tube,” Anderson said.

Beyond the 9-inch housings themselves, Moser supports the build with in-house manufacturing of axles, yokes, and gears, often boasting a two-day turnaround. “Pretty much everything that we do is a two-day turnaround, and part of the ability to be able to do that is because we make everything here,” Anderson said. “We have full control over all of our product line, whether it’s our axles that are forged less than a mile from our factory, or we do our own heat-treating in-house.”
