44a axle swap, d/s lenght, what do you think? (pics)

Im in the process of doing my axle swap, and im worried i may have to get my d/s shortened but its really a close call. I know most people shorten their d/s 1.5" but im at about 5" of lift. Im thinking i may need to shorten it about 3/4" just to be safe. I dont want the driveshaft shattering the t-case. What do you guys think?

This is at full extension, tires hanging in the air, with frame of jeep supported by the lift.


This is at full compression, shocks a hair from bottoming out.


This is just to give you an idea of how long the splines are

only benifit i see leaving as is, is reducing the chance of driveline vibes. Seeing as how the d/s is at less of an angle with it being closer to the t-case, plus it will have plenty of spline engagement.

only downfall i see is there only being roughly 3/4" of forward travel before it hits the t-case, but then again the shocks would over extend well before that ever happened.

I'm at 5.5" of lift and did not need to shorten at all. You want around 1.25" of shaft showing at ride height. I wheeled pretty hard a few weeks ago (first run with the 44a) and have no problem with rear driveshaft.

Let it be, looks great as is. I'm at 6.5" and mine looks almost the same as yours. It's been this way for a couple years and I've had no issues on or off road.

Looks fine...grease the splines and/or put a boot on it...a shock will work.
