Why was the driveshaft shortened? Internal to external slip yoke?

I will definitely hit you up if I need anymore details, I'm feeling pretty solid about it at this point t though.
I don't mean to bomb your thread but I just PM'ed you there buddy.

the 249 i took out was internal slip, the 231 from the xj was external. i removed an inch, this allows exactly one inch of slip before the shaft runs into the tcase, hope it is enough?

When the axle droops the drive shaft compresses and extends when it's horizontal so with the extra fat chicks you should be fine.

I never said anything negative about fat chicks. The ZJ drive shafts are very long. There are plenty of folks on here taller than that with stock shafts.

Do you have the CV or u-joint type in the front? CV type will eat itself at about 3" of lift, u-joint type should be ok.

The rear isn't going to be an issue, I'm just under 6" and still with the stock shaft.

I will be going from an ISY to an ESY when I swap my 231 in as well, however I'm also going to be lifting it 4.5 inches at the same time I do the t case swap. From what you guys just said, it sounds like I will still need to shorten my DS since I could go over 6 before I would have to possibly get it lengthened. Am I understanding that correctly, or is there a chance I may not have to shorten it since I will be lifting as well?

i have the double carden (u-joint) front shaft, so i should not have an issue at 5.5"?

thanks for the confirmation on the rear shaft, it is appreciated

i would definitely check the fit before committing to shortening the shaft, you may not need to do it, good luck Sir!
