Hey there, fellow gearheads! If you’re looking to give your ride a serious upgrade, check out the Yukon Gear & Axle spider gear kit. This isn’t just any run-of-the-mill replacement; it’s built to last, using top-notch materials and production techniques that really show when you hit the road. I’ve seen these kits hold up under some serious stress, so you know you’re getting quality.

This kit is specifically designed for Ford 8.8" differentials that are rocking Yukon Dura Grip or Eaton positraction units. What does that mean for you? Well, if you’ve got 31 spline axles, you’re in the right place. You’ll get everything you need to replace your spider gears without any hassle. Inside the box, you’ll find two side gears, two pinion gears, a cross pin shaft, a roll pin, and some thrust washers to keep everything running smoothly. Just a heads up, though—this kit doesn’t come with clutches, so make sure you’ve got those sorted out separately.

Here’s a quick rundown of the specs:

  • Grade Type: Regular
