The cheapest but also the right way to lower your truck is to get ahold of AIM and pick up one of their 4" rear kits which consists of the shackles and hangers. On the front, you can either cut one coil(no more) off the stock springs or buy a 2" dropped aftermarket set. You can also get these coil springs from AIM also. If you choose to cut your stockers, the best way is to remove the coils from the truck(be VERY careful) and use a die grinder with a cut-off wheel to remove one coil. This won't ruin your coils from heat. You CAN use a torch after removing them, but when you do it that way, you need to submerge the part you aren't cutting off in a bucket of water so the water will absorb any heat that is transferred into the remainder of the coil. If you've never done any suspension work like this before, find someone who has for help.
