Product Details
This is the Yukon Gear & Axle Ford 9-inch differential dropout assembly, a complete unit built by expert technicians. It's designed to be a direct replacement for your Ford 9-inch housing, making the upgrade process much simpler. You just install the third member, bolt on the cover, add fluid, and you're ready to go. This assembly comes with a 3.70 gear ratio and 31-spline axles, and it features a Trac-Loc clutch-type limited slip differential.
The nodular iron case is a solid upgrade over standard housings, offering improved rigidity and better power handling. This means less deflection under load, which helps maintain consistent gear contact for a longer service life. The Trac-Loc limited slip differential is a significant improvement for traction, especially when you need to get power down to both rear wheels. It's a well-built unit that's properly shimmed and set with the correct backlash right out of the box, saving you a lot of setup time.
This dropout assembly fits a wide range of Ford vehicles equipped with the 9-inch differential, including popular models like the Ford Bronco (1966-1986), Ford F-100 (1957-1983), and Ford Mustang (1965-1973). It's important to note that this assembly does not include the driveshaft yoke, so you'll need to reuse your existing one or purchase a compatible yoke separately.
