How large are the procomp springs?
I've never needed any spring compressers for the DPG kits and I've installed a share of them.
Set the front or back up on jack stands right behind the control arm mount.
disco sway bar.
Remove track bar.
LOOSEN CONTROL ARM BOLTS.....yes there is a reason.
Just loosen them.
Lower axle with jack.
Place jack on opposite side of axle you are removing/installing the spring on. Jack it up. It will push the other side down some.
Install bump stops extentions.
Move on to other side.
Complete other side.
Install new tracbar. (set length using factory trackbar and add 3/8'' in length. (this will get you close to center. You will still need to tweek it after you get in set on the ground)
Lower vehicle to the ground.
TIGHTEN CONTROL ARM BOLTS.
Install shocks (can do this at any time after the springs are in)
Install new swaybar links.
Center axle with trackbar.
Move to rear.
