If you're diving into a differential rebuild, the USA Standard Master Overhaul Kit is what you need to get the job done right. I’ve used this kit on my own Jeep, and let me tell you, it really takes the guesswork out of the equation. You want to make sure everything fits perfectly, and this kit delivers.

It’s designed specifically for the standard rotation Dana Spicer 30 front, which means you can trust it to fit like a glove in your rig. Inside the box, you’ll find Koyo bearings and races, which are known for their durability and smooth performance. They’re not just any bearings; these are the kind of components you want to rely on when you’re out on the trails.

What’s included? Well, they’ve packed in everything you need to wrap up your install. You get carrier bearings and races, pinion bearings and races, a pinion seal, and axle seals. There’s even a complete shim kit to help you dial in your setup just right. Plus, they throw in ring gear bolts, a pinion nut, oil baffles and slingers, thread locker, and marking compound with a brush. Oh, and don’t forget the gasket—because who wants a leaky differential?

And just to give you peace of mind, there’s a one-year warranty against manufacturer defects. So if something goes sideways, you’re covered.

This kit fits a variety of models, including:

• American Motors Eagle (1980-1987)
• Ford Bronco (1966-1971)
• International Scout II (1971-1974)
