Do I need a lond travel drive line?

I have 3" allpro's with a 7" eye to eye shackle. I just recieved my shock hoops, so I will have longer shocks. I plan on going to hysteer.
Can I simply have the stock shaft lengthened, or will I have enough travel to need a long travel?

won't know for sure until installed....once all else is done, "hang" the truck from the frame and make sure the axle droops completely. Make sure you have at least a couple inches of spline connecting still.

When I did my SOA lift and raised the truck like that, the driveshaft fell out. Some measurements and I discovered I used a worst case 7" of stroke...

EDIT: test the droop without shocks, that way it's a "for sure" worst case.

My first guess is yes but the stock yoda shafts have quite a bit of travel.

7" shackle sounds awful long, hope you have steel shims under the spring to fix pinion angle. With long travel shocks you are pushing it, with stock mounts I got away with it for awhile but the shocks were short and limited travel.

How do I measure the total compression? or does it not matter as much because there will be more droop than compression?

with the truck at its static postion I measure 30" from the pinion nut to the nut holding the flange on the t-case.

Are the toyota u-joints something that I need to worry about? I have 33"s now, but plan to go to 35's. Are the stock ujoints strong?
