Select the year of your Ford Bronco:
If you're diving into a differential rebuild, you’re going to want a solid kit that’s got your back from start to finish. That’s where the Yukon Master Overhaul Kit comes into play. I’ve used these kits before, and let me tell you, they’re built with everything you need to get the job done right. No more running around trying to find that one elusive part—you’ll have it all right here.
What sets Yukon apart is their attention to detail. They’ve put in the work to offer a wider selection of tailor-made kits than anyone else out there. This particular kit is designed for the 1980-1982 Dana Spicer 44 IFS, which is a popular choice for those of us who love our classic Ford Broncos and F-150s. It fits a range of vehicles, too, including the Ford Bronco and Ford F-150 from 1980 to 1992, as well as the F-250 up to 1990. So, if you’re working on one of these models, you’re in luck.
Now, let’s talk about what’s actually in the box. You’ll find Timken bearings and races, which are known for their durability and reliability. Those little details matter when you’re tackling a job like this. Plus, the kit comes with high-quality seals and all the small parts you might need. You get carrier bearings and races, pinion bearings and races, a pinion seal, axle seals, and even a complete shim kit. They’ve thought of everything, right down to the ring gear bolts, pinion nut, crush sleeve, thread locker, marking compound with a brush, and a gasket. It’s like they packed a toolbox into one kit!
Yukon really did their homework to make sure this overhaul kit is comprehensive. You won’t be scratching your head wondering if you forgot something. It’s all there, ready to go, so you can focus on what you love—getting your ride back on the road or trail. Whether you’re a DIYer or a small shop owner, this kit is a smart investment for any differential job.
