I keep reading on here that you shouldn't install a tcase drop on a zj but almost all lifts come with one.

What is it that the jeepforum users know that iro, kevins, rc, bds, etc. don't know?

Usually not needed or never needed? I just can't wrap my head around why a company would go through the r&d process for a product that isn't needed.

maybe if it has a 7+ lift

but if you drop the back end of the transfer case the front would still be high and what would the point be of the lift if you drop the case down 3 inches? on a zj your best bet is a high pinion axle front and back, and if you have money than do it right and get better axles

The rear driveshaft in the ZJ is long enough that even at 7" of lift you don't need to be messing around with it. The operating angles are fine for the joints on the drive shaft. A transfer case drop will actually hurt the front angle, not to mention lose you clearance that you just paid hundreds of dollars for. The front shaft should be addressed (lengthening/swapping joint styles) if needed. HP axles are not "needed/best bet" and you can safely run larger tires on non-HP axles.

On a TJ or the SWB Jeeps, the rear driveshaft is much shorter and lifting puts it at a steeper angle.

Yea but the local 4x4 shop who works on Chevys and Fords said I would need one along with a drop pitman and SYE.
