If you’re diving into a re-gear project, the Yukon Gear Kits are where it’s at. These kits come with everything you need to get your differential sorted, all in one neat package. You’ll find front and rear ring and pinion gear sets alongside the Yukon Master Overhaul Kits, which means you won’t be scrambling for parts halfway through your build. Trust me, I’ve been there, and it’s not fun.
Yukon Gear & Axle has built a solid reputation in the automotive world, and for good reason. Their high-performance ring and pinion gear sets are top-notch. The engineers over there don’t mess around—they use cutting-edge design techniques and advanced heat-treating processes to make sure these gears are tough enough to handle whatever you throw at them. Plus, they put their products through rigorous quality testing to ensure they meet exacting standards. You can feel confident knowing you’re getting a product that’s built to last.
These kits are designed to make your life easier. They come with all the gears, bearings, and those little parts that you often forget about but need for a complete rebuild. You can choose from gear ratios ranging from 3.73 to 5.38, which gives you the flexibility to tailor your setup to your needs—whether you’re looking to beef up your towing capacity, tackle some serious off-roading, or simply replace worn-out gears.
One of the standout features is the Y.E.S. Plan that Yukon offers. This lifetime protection plan covers your gear set kit for as long as you own your vehicle. No questions asked. It’s a nice peace of mind knowing you’re backed by a company that stands behind its products.
Now, let’s get into some specifics. This particular kit includes a 4.11 Ring & Pinion Gear Set, which is perfect if you’re running larger tires or just want that extra oomph when you hit the gas. The ring gear diameter is 10.5 inches, and it’s compatible with applications that have a 12 Bolt Rear Cover and 12 Bolt Ring Gear. That’s a solid fit for models like the Ford Excursion from 2000 to 2005, and the F-250 and F-350 from 1999 to 2007.
In short, if you want to save both time and money while ensuring you’re using quality components, these Yukon Pro Kits are a smart choice. They include everything you need in one simple part number, so you can focus on getting your vehicle back on the road—or off it, if that’s your style.
