Dynatrac makes the ProRock 44 and Dana the Ultimate 44 only for JL front axle applications. There’s only 60 and 80 series upgraded rear axles. Why is this?

I'm surprised someone doesn't make a full float conversion kit for them.

Warn made them at one time for the Dana 44's in the TJ's. I ran the setup and loved it. It had stronger axle shafts but the full float design making it so much better in my opinion. Wish someone would make it for the JL's.

The PR44 and Ultimate 44 aren’t full float although that would be great. Or a conversion kit like you suggested. But if you’ve got a Rubicon and want to upgrade both front and rear, you have to go to a 60 or 80 rear. No option for a stronger rear 44. Which means doing the same in front since the 60/80 are 8 lug and the 44 isn’t.

Was just discussing this with another member here. Kind of silly a UD44 rear isn't offered. That 60 would probably be hard on the v6 and the turbo, not to mention the hole patterns.

I got to wheel with my UD44 front last weekend and loved it. Definitely a confidence booster not having to worry about it breaking easily compared to the D30 with 37s.

Wow, that's pretty awesome. The expense of upgrading to 60's AND having to update wheels, compared to having the option to upgrade gradually is a game-changer.

Great video Dynatrac added as well:

Are they gonna make a comparable front 60 where we can keep our current wheels? If I'm gonna go 60 in the rear, I want a matching 60 up front......

Why would a 60 be hard on the motor? People have been rolling tons with 4-bangers for decades.
