$1599.89

If you're diving into a re-gear project, let me tell you, the Yukon Gear Kit is where it's at. This isn’t just a random collection of parts; it’s a carefully curated set that comes with everything you need to get your differential sorted out. You’ll get front and rear ring and pinion gear sets along with a Yukon Master Overhaul Kit—all under one part number. Talk about convenience!

Yukon is known for their high-performance gear sets, and honestly, they’ve set the bar pretty high in the automotive world. Their engineers have put in the work, using some fancy design techniques and top-notch heat-treating processes to make sure these gears are tough and ready to handle whatever you throw at them. The quality testing is rigorous, so you can trust that these parts meet the exacting specs you need.

Now, let’s break down what’s in the kit. You’re getting the gears, bearings, and all those little bits and bobs required to rebuild your differential. The ratios range from 3.73 to 5.38, which means whether you’re looking to up your tire size for some serious off-roading or just need a bit more towing power, there’s a setup here that’ll fit your needs. Plus, if you're replacing worn gears, this kit has got your back.

One of the standout features is the Yukon Dura Grip Clutch Style Limited Slip (LSD), which is fully rebuildable. That’s a big deal if you want to maintain performance over the long haul. And let’s not forget about the bearings and seals—everything you need to get your vehicle back on the road without a hitch.

Here are some quick specs:

  • Differential Carrier Bearings have a 2.891" Outside Diameter
  • Designed for applications with a 10 Bolt Rear Cover and 10 Bolt Ring Gear
  • Includes premium Yukon ring and pinion sets and high-quality Timken bearings
  • 8.5" Ring Gear Diameter
  • This particular kit features a 4.56 Ring & Pinion Gear Set

And if you’re worried about long-term support, Yukon has a Y.E.S. Plan—a lifetime warranty that covers your gear set kit for as long as you own your vehicle. It’s nice to know that you’re covered, right?

Now, for fitment, this kit is compatible with a bunch of models:
