I have done this several ways. The Ford tool is pricey, its an internal compressor with rounded plates that fit the springs nicely, and ball joints at the nuts where you tighten it.
Shorter front springs can be installed without a compressor, you remove the sway bar, tie rod, and lower strut bolts. Insert the spring and coax it into both spring pockets and jack the lower arm back up. It still can be a mother.
I ended up taking two pcs of 1/2 in thick steel, about 2 by 5 inches, and putting a hole in the middle for 5/8 or bigger threaded rod. This is the country boy spring compressor. I cpmpress the spring in my press or by tightening the nuts before I install it. Make sure the long end of the rod sticks out the hole in the lower arm.
The country boy would jack the spring under the trailer hitch to an F250 as tight as possible and wire it closed with coathangers or short pieces of chain. I have not done this one, but others have and it works. A steel banding tool is considered the ultimate for this approach.
I also have the KD tool, and it would work but the threaded pcs with the hooks are too big to remove through the hole in the lower arm. You could just get one of these and enlarge the hole.
