If you're looking to breathe new life into your GM's differential, the Yukon Gear & Axle spider gear kit is a solid choice. I've been around the block with these things, and let me tell you, they pack a punch. Unlike the stock options, this kit is built with higher quality materials and superior manufacturing processes. That means you’re not just getting a replacement; you’re getting a set that’s designed to last longer and perform better under pressure.
This kit is tailored for the GM 7.2" IFS, which covers a range of vehicles like the Chevrolet Astro from 1990 to 2005, the Express from 2003 to 2014, and even the S10 models from '83 to 2002. It’s a versatile piece that fits a good number of GM trucks and SUVs. You get two side gears, two pinion gears, a cross pin shaft, a roll pin, and spider gear thrust washers—all the essentials you need for a complete and proper replacement. No hunting around for missing pieces here.
In terms of specs, this is a regular grade type kit, but don’t let that fool you. It’s built to handle the rigors of daily driving as well as some light off-roading if that’s your thing. I’ve seen these kits hold up under some serious conditions, so you can trust that they’re going to keep your ride smooth and reliable.
So if your spider gears are showing signs of wear or you’re just looking to upgrade, this Yukon kit is worth considering. It’s straightforward to install, and once you’ve got it in, you’ll notice the difference in how your vehicle handles. No more worrying about those clunky noises or sluggish performance. Just solid, dependable driving.
