    i have a four in lift, and am wondering if i need to just drop the t-case or get a new drive shaft. If i do get a new driveshaft, do i still need to drop the t-case?

    With only 4" of lift dropping the t-case should solve all your problems. 6" or more and you'll need to lengthen the driveshafts.

    they are actaully 1/2 " short from the factory- so really yes on a 4" just to keep from pulling it apart on hard breaking-

    I have a 4" lift on mine and I used to have a baaaad vibration so I lowered the t-case using the factory spacers and voila!! No more vibrations!!! That is all you need, no lengthening of the driveshafts.
