I'm not making this an instruction sheet for removal/installation of shocks. If you have never done this before, I suggest YouTube and any instruction sheet. However, some tips to remember:
Relieve the pressure out of the stock air shocks before removing the tubing. If you don't, you take the chance of oil escaping from the shock.
Make sure to store the stock air shocks in an upright position OR plug the air holes with something that will not allow the oil to burp out
Have a good lift that can adjust in small increments easily. With that in place, it's so much easier to relieve the pressure on the shocks prior to removal and to get the shock mount holes aligned with the shock with little or no effort.
I suggest keeping the stock air tubing along with the primary side Schrader air valve in place. I plugged the tubing with a good, rubber tip in each with a micro zip tie to keep it in place and then zip tied everything out of the way and out of sight. If I do decide to go back to the stock air shocks (unlikely), everything is still in place to complete the project easier.
Really, the only tools this takes besides the lift is a 3/4" socket and ratchet and, if you are truly "by the book", a torque wrench (before you ask, yes I do).
