Big lifts, and larger tires are great, but what is on the inside is what matters. This is true when it comes time to look at Jeep axles. We looked to Dynatrac and their JK44 axleshaft kits to find out about their product.

We asked Cole Quinnell about the idea behind these kits, “The idea behind the Dynatrac JK44 axleshaft kits was to provide a significant improvement in strength with a US-made kit. This let’s someone build an ultimate ProRock 44 using Dynatrac axleshafts. There’s also a lot of JKs out there that don’t need to upgrade to Dynatrac ProRock XD60s, but can use more strength than the stock Dana 44 axheshafts offer.”

The axleshaft kits are made from chromoly and have a proprietary Dynatrac heat-treating process for added strength. The front kits include new 1350 U-joints and the rear kits include billet retainers and ABS tone rings.

That’s all great, but when is it time to upgrade, “If you’ve twisted or broken an axleshaft, but aren’t ready to upgrade to a Dynatrac ProRock XD60, or if you simply want to strength your stock Dana 44 axles as much as possible, then it’s a good idea consider the Dynatrac JK44 axlehshaft upgrade. It’s also a natural upgrade for the front axleshafts if you’re installing a Dynatrac ProRock 44 since you’ll have the front axle taken apart to move the locker into the new housing.”

“If you’re upgrading the stock rear axle, Dana 44, in a JK with an aftermarket locker, that’s a great time to install a set of Dynatrac JK44 rear axleshafts. This provides a significant strength improvement and eliminates the factory axleshaft retainers with new billet ones which will last longer and make future axle service easier,” Quinnell said.

The big take away from all of this is to make sure that what is inside your axle housing matches what you are doing out on the trail. For more information on Dynatrac products be sure to check out their website.
