SoK66, We won't say anything bad about the Tera axle, but we are curious what you saw on our ProRock 44 axle that makes you think that our quality isn't the same or better? Also, where did you see our axle? We pride ourselves on excellence in design and manufacturing, and if something with the Dynatrac name on it doesn't that live up to that, we definitely want to know about it!

I have a for sale thread on here. Have them listed for $9500 but would consider some trades as well like firearms and tools. I could also look at taking some factory axles in trade depending on what they are and set up. Not interested in any dana 30's with 3.21 or 3.73 gears in them.

Thanks for chiming in. The PR44 is certainly a fine product. Comparing two PR44 Unlimiteds owned by club members to my TF R44 the PR44s lacked control arm mount skids, multi-holed track bar mount brackets (the PR44s required installation of Synergy brackets at extra cost) & diff drain plug. The tech who installed my R44 commented that the gear setup process on the TF housing was far easier than PR44s he'd installed. Finally, On my setup TF's spring buckets were more favorable due to the bump stop pad design. For those who've never seen one, TF's welding is a work of art, to the point when they saw it one of our our local fab shops photographed it to use as an example of fine welding.
I'm certainly not here to bash Dynatrac, I had your axles on my previous rig. However I was not going to let that "POS" comment go without responding. Helps to know what you're talking about before dissing someone's product.

Thanks for your reply, and we’re glad you’re not here to bash Dynatrac! You probably already know these points, but so that no one else is confused…the Dynatrac ProRock 44 is available with two versions of the track-bar-bracket mount. One standard height and one raised height. Our raised-height bracket now has an integrated steering-ram mount. This simplifies installations where people are using a steering-ram assist, or might in the future. You are correct that we don’t put skid plates on the lower control arm mounts. Early on we found that these can interfere with some aftermarket suspension systems. Our brackets are plenty strong with these extra plates, and it is pretty easy for a shop (or a Jeep owner) to fabricate these skid plates for themselves if they want that will clear their specific suspension arms. As for gear set up, please have that shop call us any time he has trouble setting up gears in one of our housings. We’ve sold more ProRock 44 housings than all competing aftermarket axles combined, and we rarely run into trouble with gear setup. We hope your axle performs as you expect for a long time, and we hope that you’ll consider us for your next project.

Would you consider a trade for a PR44U (35 spline ARB RCV, Dyna ball joints) and SF PR60 in 4.88's practically brand spankin' new? The PR60 will be ordered here in the next 2 days so I can still change the rear diff to ARB, EATON, etc. They are stock JK width.
I could probably make do with the 3 link up front but I'd definitely need to get the rear CA mounts back to stock and have rear spring perches welded in. I've got the EVO King's LCG front kit sitting here waiting. Was originally planning to keep the rear AEV coil/strut for the time being. I'm planning 3"-3.5" lift.
The main issue is the 5.13's. Not sure how I feel being in the 2700 RPM range on 36/37's since it's a daily driver so that's why I haven't pulled the trigger on yours....

Where is it leaking from? If it is from the differential cover, it probably wasn't sealed up good by whoever installed it. Also, someone was talking about the fact that the drain plug isn't at the bottom on the PR44. While I agree it would be nice, it's definitely not a deal breaker considering the extra ground clearance you get over the other housings available, and it also allows you to inspect the internals when you do change the gear oil.
