If you're looking to step up your gear game, the Yukon Gear & Axle ring and pinion set is where it's at. These aren’t just any gears; they’re crafted with precision and built to handle the demands of heavy-duty use. Yukon’s engineers have put in some serious work to make sure these gears are tough enough for whatever you throw at them. They use advanced heat-treating techniques and rigorous quality testing to ensure that every gear meets high standards, so you can trust that you’re getting something reliable.

Now, if you’ve cranked up the horsepower or slapped on some bigger tires, you know that you need a gear ratio that can keep up. This set comes with a 4.30 ratio, which is perfect for optimizing traction and getting the most out of your ride. It’s designed to fit a 10.5" differential, so it’s compatible with a bunch of Ford models from '99 to 2010. You’ll find it fits the E-250, E-350, Excursion, F-150, F-250, and F-350. Just keep in mind, it’s all about that specific fitment.

Here’s the nitty-gritty on what you’re getting:

• Fits 1999-2010 Ford 10.5" differentials
• 10.50" ring gear diameter for solid performance
• 31 spline pinion for durability
• 12 ring gear bolts to keep everything tight
• 4.30 gear ratio for that perfect balance of power and efficiency

Keep in mind, this set doesn’t come with mounting hardware, so you’ll need to grab those separately. And if you’re worried about longevity, Yukon’s got your back with their Y.E.S. Plan, which offers a lifetime protection plan. That means as long as you own your vehicle, you’re covered—no questions asked.

So if you’re ready to boost your truck’s performance and tackle those tough terrains, this Yukon ring and pinion set is a solid choice. Just be sure to double-check your fitment to make sure you're all set for the upgrade!
