I experienced the same thing from Evo and Dynatrac. The 72.5" XD60 and EVO plate seem to be one offs. To go to 72.5" on my XD60 was another $3k because, what I was told, they would have to pay engineering time to make sure it was correct. I saved the $3k and got the XD60 with 1480 outers so I could run the DTD since Evo confirmed DTD doesn't work with the 68.5" 1550 outer setup. Were two bummers but my XD60 is still a frickin' monster.

My understanding is the additional turning angle of the XD60 with the 1550 is what causes the problem with the DTD. You could either go with a somewhat custom build like Eddie, or limit the turning angle of the 1550. I'm in the process of setting mine up with the Evo coilover's. Still not sure what I'm going to run into, but I'm sure there is a way to make it work.

Give Dynatrac a call. I think they might be able to help you out.

Do you recall the process for setting the caster and pinion on the XD60? For some reason I I'm thinking they added addition caster to the inner c's to account for lifted Jeep's when they install them, but can't seem to find the values.

I would say aim for the 4.2 and then visually look at your pinion angle. Or check your Dynatrac invoice, it's pretty detailed and may have it listed if your axle came that way. Ideally the pinion angle and driveshaft angle should be parallel. If you can achieve that and still have higher caster, you're good.
Your axle has +6° of caster built into it.

So it has +6 degrees similar to a stock axle or 12 total?

Stock has +4.2° of caster.

That's right! Thanks. Just got my ProRock 60s installed this weekend and was wondering about the angle relationship.

Moby has his ram mounted to the axle using a welded on EVO bracket and connects to the passenger side knuckle. The XD60 uses its own mount extending from the track bar bracket and connects to the tie-rod using a clamp. They're totally different setups.
For those of you who haven't seen, the all new JL Wrangler Rubicon will be coming with a set of 68" wide axles. That's a whole 2.5" wider than what come on a JK and just a 1/2" shy of a full width axle. With that said, it seems that Dynatrac has been way ahead of the curve on this one and it wouldn't be so far fetched to think that the new "full width" will now be 72.5". :yup: 
If you're referring to the EVO Lever system in the rear, the coil overs are simply mounted to the rear cross member on one end and to a cantilever arm attached to a frame on the other. The cantilever arms are linked to the axle and this allows for 14" of vertical travel. Sorry, I don't have a diagram but you might be able to get a look at how this all works in this video.

It’s Dynatrac’s Hardcore Plus XD60/XD60 that comes with the new knuckles, correct? What is the most backspace you think a non-coil over could run, on a JK?

Nope, you didn't imagine anything and yes, you heard right, we still run factory track bars on both Moby and Rubicat. Of course, we're just mall crawlers.

Well duh! You mall crawlers always use the stock stuff cause oem isn’t good enough:rock:
Thanks Eddie! That saves me some dough!
