If you're diving into a re-gear project, the Yukon Gear Kit is a solid choice. This kit packs everything you need to get your differential sorted out, all under one part number. You’ll find both front and rear ring and pinion gear sets, along with a Yukon Master Overhaul Kit that makes life a whole lot easier.
Now, let’s talk about the gears. Yukon’s high-performance ring and pinion sets are known for their quality. These guys don’t mess around—engineers use top-notch design and advanced heat-treating techniques, ensuring that the structure and finish of the gears meet some serious standards. You can choose from ratios ranging from 3.73 all the way up to 5.38, so whether you’re looking to boost your towing capacity or just want to replace some worn-out gears, they’ve got you covered.
One of the standout features of this kit is that it comes with all the little bits and pieces you need to rebuild your differential. We’re talking about gears, bearings, and all the necessary small parts that can make or break your installation. Plus, if you’re thinking about upgrading your tire size or hitting the trails more aggressively, this kit will help you clear those bigger tires without a hitch. For example, if you're running a 4.11 Ring & Pinion Gear Set, you’ll find it fits nicely with various setups, including Ford Excursion models from 2000 to 2005 and F-250/F-350 models from 1999 to 2007.
And let’s not forget about the warranty. Yukon’s Y.E.S. Plan offers lifetime protection for your gear set kit as long as you own your vehicle. It’s a nice peace of mind knowing that you’re covered if anything goes sideways.
