99 4WD & Fabtech

[WPG2013]

So, I'm about to pull the trigger on a 6" Fabtech lift. In the disclaimer it states ,"Will not work with fulltime 4WD Models". WTF! Apparently, after talking to the tech at Fabtech, some Expys, not all, it's a crap shoot, flip a coin, take a wild guess, may or may not, have driveline vibration!! Really! Now I feel like I'm going back to square one for a lift kit.

The back page of the lift manual I believe (been a few years), or the website has the specs for a driveshaft that won't vibrate. Just take it to a driveshaft shop and they can build it.
