The reviews show what the products can do, but how do the Dana 30 and Dana 44 compare to each other? Let’s talk about that.

Center Section

Here, we’re taking a closer look at the gearings and the center housing too. The center section is responsible for holding the differential, meaning that the build material doesn’t need to be strong unless you’re dealing with a ton of power.

The Dana 30 features ring gear that measures 7 1/8” of diameter, featuring 3.21 gear ratio.There’s no factory LSD, or locking differential included.

On the other hand, we have the Dana 44 measures 8 1/2”, which offers a 4.10 gear ratio. Additionally, there’s an actuated locker.

The center section housing is larger, which helps accommodate the large ring gear.

The reason you could use a larger diameter ring gear is that it’d help to handle the load, reducing the risks of breaking due to the stress.

Axle Shafts

While the Dana 30 features 27 spline axle shafts, the Dana 44 has 30 instead. That means the latter is far better than the first.

Nonetheless, both units have rather weak ears, and the two come with relatively small u-joints.

What About the Rest?

Although there’s a significant difference in the features discussed above, everything else about both the Dana 44 and Dana 30 is pretty much the same.

We’re talking about the brakes, hubs, knuckles, steering, and many more, which are all the same thing.

Even the axle housing is the same, which means that you’d need Dana 60 if your purpose is to do high-speed activities on surfaces like the desert.

FAQs

What is the axle housing?

The axle housing keeps everything together. Its strength and durability are essential, as they’d dictate whether or not you’ll be able to tackle tough terrains like the desert. Both the Dana 30 and 44 share a similar axle housing.

Why is the larger ring gear more important?

Ring gear with a larger diameter guarantees proper load distribution, reducing the stress and pressure that could cause any breakage.

What are the differences between Dana 30 and Dana 44?

The main differences are the strength of the housing, the center section as well as its features, and the axle shaft design.

Are there any similarities between the Dana 30 and Dana 44?

Yes. In fact, both components feature plenty of similarities, such as the brakes, the hubs, ball joints, knuckles, and the steering.

Other than the differences mentioned in the previous question, everything else is pretty much the same.

Which one to choose?

Many people would recommend going for the Dana 44, as it’s the stronger option out of the two.

Conclusion

Once you look at them in-depth, you can tell the differences between the Dana 30 vs. Dana 44 are mainly the ring gear size, the automated locker, and the size of the shafts.

For beginners, the ideal pick would be the Dana 44, as many people consider it a true 44.
