I would also recommend dynatrac. I had the tera crd 60 in the front of my TJ and while it was one of my favorite mods it wasn't witout issues. The coil springs would not fit on the "perches" with the bumpstops installed without modification. The brake pads weren't centered on the discs and they had about an eighth of an inch overhang where the pad didn't contact the disc. Also, even though I ordered it for their 6 inch lift it barely aligned within acceptable range between the pinion angle and caster angle. Now all of these were small issues but I think show some lack of attention to detail.
The pr44 I just installed on our jk however fit perfect except for the off road evolutoon trackbar bracket, hardly dynatrac's fault as this was due to the larger axle tube.
There is two different brackets. One for a ProRock and one for a factory axle.
