It is an easy process if you know where everything is located... Jack the truck up and put jackstands underneath... Trace the torsion bars back to where it meets the frame--then crank the bolts (5-10 turns) evenly on both sides--you may want to get a pencil or chalk to set witness marks so you know you get both sides even. Once you have tighened the bolts to yield the proper ride height, drive up and down the street to "set" the new adjustments. Then get out and measure the distance between the top of the tire and the bottom of the wheel well and make sure both sides are even--repeat the process as necessary to make sure both sides are even. You may also need to trim or get new bump stops. The stock ones will be too tall once you have cranked the torsion bars... Your ride smoothness will be compromised if you perform this task incorrectly or have too tall of bump stops... You will need to go have the truck aligned because it WILL come out of adjustment. It's an easy free mod, but if you have a 4WD place close by, go visit them and ask some questions before you start.
