Its actually pretty simple. I just recently changed the springs on my 1500. You will need a hydraulic jack and a couple jack stands. Jack up your truck enough to pull the wheels off and put your jacks under the body, disconnect the sway bar and loosen the bolt on top of the shocks. Now you are ready to lower the axle down, which will loosen the spring tension. You will have to remove the shocks to install the coil spacers, which is a great time to replace your shocks, then you just reverse the process!
Hope this helps!
