Shackle Install Question

New to the pickup truck game and I am curious how you guys jack and stabilize the rear of the truck high enough to install lift shackles? Back in my Land Cruiser days I remember trying to do one side at time, the twisting of the axle made it nearly impossible, so I know I need the whole back of the truck off the ground. I have a quality 3-ton floor jack and 6-ton stands, but these seem light duty for this task and I am not sure I can get the required height. Also, placing the jack stands on the frame rails before it bends upwards makes it seem like there is a lot of ass end hanging off the back. The whole thing seems sketchy, I need a hydraulic lift.

 

Did it the other day. Easy, jack the back end up and put jack stands. Remove both wheels. Remove shackles and install new ones.

 

Coachbuilder made a real nice install video. Even if you dont have his shackles, it provides all the steps and how to work the pumpkin so can get the old bolts out easily. https://www.youtube.com/watch?v=zmJ6Xjjtpe8

 

That was perfect, thank you very much!
