If you're diving into a rear-end rebuild or just looking to fine-tune your setup, the Yukon shim kits are where it's at. These aren't just any shims; they're precision machined for each specific application, which means you’re getting exactly what you need for your ride. No more guesswork or mismatched parts—just solid performance.

One standout feature is the crush sleeve eliminator kit designed for GM 12 bolt trucks. This little gem helps you avoid the hassle of crush sleeves that can wear out over time. Instead, you get a reliable setup that keeps your pinion depth consistent, which is crucial for getting the most out of your drivetrain.

Now, let’s talk specs because we know that’s what really matters. This kit includes pinion shims, so you can dial in the perfect fitment without any fuss. Just a heads up, though—there's no gasket or seal included, so you might want to grab those separately if you're doing a full rebuild. The shims are made from durable steel, ensuring they can handle whatever you throw at them.

As for fitment, this kit is compatible with a range of classic Chevy and GMC models. We’re talking '69 to '74 and '87 Blazers, '63 to '86 C/K 10s, and even '63 to '87 Suburbans, among others. Whether you’re working on a vintage project or just need to replace worn-out parts, these shims are a solid choice.

So if you're ready to get your hands dirty and make your ride perform like it should, the Yukon shim kits are a smart investment. They’re built to last and designed for those who know what they’re doing. No fluff—just good, honest engineering.
