Dynatrac ProRock 44 JK Axle - Building the World's Strongest Dana 44Posted in How To on May 1, 2011 Comment (0)
It’s a bold claimthe strongest Dana 44 ever built. And admittedly, you could argue a few exceptions in certain components. But overall, the Dana 44-based Dynatrac ProRock JK axle has to be the strongest ever built.
Feel free to scratch your head for a second. We are in fact talking about a Wrangler-based axle, and it took us a few minutes to put together the fact that this axle is stronger than even the thick-tubed eight-lug Dana 44s found on ’70s F-250s. But after a review of the components list and options found on this axle, we think you’ll agree that this is an axle that could be considered overkill on any JK or even fullsize truck. And this is exactly why we built this one 74 inches wide (almost 10 inches wider than a standard JK housing) and are putting it under a half-ton truck with 37-inch tires. In an upcoming issue, we’ll have an update of how this axle is holding up to some prerunning, trail-running, and rock-crawling use.
Why Build a High-End Dana 44?
You may be asking yourself why you’d spend the money for a custom axle and not get a Dana 60. This is actually a good question, and there are a few reasons.
Cost - Though a ProRock 44 is still a high-end unit, it is cheaper than a custom-built Dana 60
Clearance - The ProRock 44 has more clearance than a Dana 44 or Dana 60 made. Even more than the ProRock 60
Weight - The ProRock 44 is quite a bit lighter than a Dana 60 axle, yet still incorporates many components that are nearly as strong as a Dana 60’s. OR
