USA Standard Gear Pinion Installation Kit for GM 8.5 Inch Rear Differential
$97.89

When it comes to installing your rear end, you want to make sure you've got the right tools and parts. That's where the USA Standard pinion installation kit comes in. This kit is designed specifically for GM 8.5-inch rear ends, so you know it’s going to fit like a glove. Trust me, I’ve been through the installation process enough times to appreciate a good kit.

Inside the box, you’ll find everything you need to get the job done right. We’re talking Koyo bearings and races—these are the real deal, built to last. You’ll get pinion bearings and races, a pinion seal, a pinion nut, a crush sleeve, and even marking compound with a brush. It’s all there, so you can dive right into your project without scrambling for missing pieces.

What I really like about this kit is the peace of mind it offers. With a one-year warranty against manufacturer defects, you can install it knowing you’re covered if something goes sideways. That’s something you don’t always get with aftermarket parts.

Now, let's talk fitment. This kit is compatible with a wide range of classic rides, from the Buick Apollo (1973-1975) to the Pontiac Firebird (1970-1981). Whether you’re working on a Chevy Blazer, a GMC Yukon, or an Oldsmobile Cutlass, this kit has you covered. It’s like having a Swiss Army knife for your rear end installation.

So, if you're looking to tackle that rear end project with confidence, the USA Standard pinion installation kit is a solid choice. It's got the right parts, the right fit, and the durability to handle whatever you throw at it. Get your hands dirty and enjoy the ride!
