driveshaft issues with susp lift ??

[Boggin]

just bought a 4" susp lift from The_Dealer, the axle drops are only 2.5" tuff countrys but the coils are 4"skyjackers, i was wondering if my front driveshaft will be long enough or if ill need it extended?

also my current rear driveshaft is the cv style, but i got a u joint style shaft that is exactly 3" longer, im wondering if that will bolt up in the rear with the susp lift added, or will i still need to shorten it?
thanks

Is the u-joint driveshaft a double cardan or just a single u-joint on each end?

Single

Well you need to measure pinion angles now. The output flange for the tcase needs to be exactly 180 degrees from the rearend yoke/flange. Picture a laser beam pointing out of each one.. The 2 beams would have to be parallel.
