they take the spring and put it in a hyd press, it has like a cup on each end, they compress the spring a few inchs down, then they use metal banding material and place 2 bands on each spring. It is placed about 1-2 coils from the ends , so after you cut them you can remove them otherwise the top and bottom coils will pinch the banding.. This shortens up the springs a few inchs and they will drop right in. You just place the springs ends to the recess in the control arm and upper spring mount and then bolt up your balljoints. Then just take a pair of tin snips and cut the bands, remove banding. Super simple and like I said it only takes about 5 mins a side to do.
next time call your local spring shop, like truck and trailer springs,etc. thats who does it for me.
