Driveshaft angle?

Hey guys, my dad put a 6 inch lift, 33 inch tires, and an np231 tc on his 95 zj. So now were installing a d44 in the rear and putting a whole new truss kit on it and we need to know what the driveshaft angle should be so we can weld the truss kit on accordingly. So what is an ideal angle for the rear driveshaft????
thanks

the right angle.
if he has a slip yoke eliminator. point the pinion at the drive shaft.
if not, make it parallel with the tcase output.

if you want it "perfect" you need to have it under the jeep and lined up where you want it while tacking everything on.

there's no "one size fits all" answer for any given lift and tire combo.

he has both upper and lower adjustable long arms. He was told by the MFG to set his rear pinion at approximately 15 degrees, but he would like some confirmation before welding his truss kit on.

15 is probably a bit high for an sye equipped grand. Does it even have a rear cv drive shaft? You didn't specify.

To get it right. You need it under the jeep to do the measurements. End of story.

Yup, get the body at ride height with jackstands under the frame, axle in position with proper pinion then tack everything, roll it back out and finish burning it in

Yes he's going to order a cv driveshaft after all the mounts are welded up.. The front driveshaft is about 2" short so he has to have a custom one made for the rear

You must do the sye first. Otherwise you're just guessing.
