USA Standard Gear Dana 30 Gear Set Ring and Pinion Replacement 3.54 Ratio ZG D30-354 - ZG D30-354

If you're diving into a project that involves your Dana Spicer 30, you’re going to want to check out these USA Standard ring and pinion sets. Trust me, these aren’t just any gears; they’re built to give you that peace of mind during your install. I've had my fair share of experiences with different gear sets, and these have proven to be reliable time and again.

First off, let’s talk specs. This set features a 7.20-inch ring gear diameter, which is pretty standard but solid. The 26 spline pinion is designed to fit snugly, and you’ll find it comes with ten ring gear bolts to keep everything locked down. The 3.54 gear ratio is a sweet spot for those looking to balance power and efficiency, making it a great choice whether you’re hitting the trails or cruising around town.

What I really appreciate about these gears is that they fit without a crush sleeve, which simplifies the installation process a lot. You won’t have to fuss with that extra step, and that’s a win in my book. Plus, USA Standard Gear backs their product with a one-year warranty against manufacturer defects, so you can feel a bit more secure about your investment.

Now, if you’re wondering where these bad boys fit, they cover a wide range of vehicles. From the classic Ford Bronco (1966-1971) to the Jeep CJ series (like the CJ5 from '71 to '83), and even some Volvos, you’ve got a lot of options. Whether you’re working on an International Scout II or a Jeep Grand Cherokee from the '90s, you’ll find a fit here.

In short, if you’re looking to upgrade or replace your ring and pinion, these USA Standard sets should be high on your list. They’ve got the specs you need and the reliability you want when you’re out there pushing your rig to the limit.
