Minimum 3T jack stands under the frame each resting on 8X8X16 blocks. I filled the blocks with Quickcrete then used liquid nail to put plywood on top. I have my stands set at about the half way mark.
With the vehicle at a slight angle and the rear end in the air, the E brake is unavailable. I found a set of wheel chalks at Wal-Mart for $5 ea. I stuffed those under the front wheels.
The blocks are stout. Figure on 1 bag of Quickcrete per 2 blocks.
Jack the vehicle up high enough for the blocks-stands to get under the frame.
The drop the vehicle until the springs are at full droop. I secure the axle on some smaller stands and removed the springs. These stands are set at the min level.

Im putting 4" shackle flip on mine with 56" 1T springs and ORD zero-rates. There should be enough room to do 8" springs or any combo thereof.....
Pretty much the same thing for the front.

Only reason my tank is dropped is for the shackle flip....need access inside the frame rail. If your not doing a flip then you wont need to drop the tank.
