OK,

Ive got an 05 LJ with a 4.5RESF/ 1.25BL/ 1MML. Right now am running the stock rear driveshaft with the stock slipyoke. I am preordered for the Rokman belly-up. I don't have ANY vibes right now. Run everyday at 75 or so MPH.

Does anyone have any EXPERIENCE with a similar setup with the belly up? I think the belly pan raises about 2.25". I would think the angle is ok, but what about shaft length? How much yoke needs to be in the TC at ride heighth?

Has anyone just lengthened the stock shaft without a SYE/CD conversion?

You will need an SYE/CV shaft with a belly up in an LJ. But if you want to run the stock slip yoke, you could have a double cardon joint welded onto your shaft?

I would bet you are right on the edge angle wise, and the belly up will give you vibes.

I would plan on the SYE and a new driveshaft.

I had the 4.5" RE lift and added a RockKrawler Bellyup (raised the TC about 1.5") and needed a SYE.
