nope didnt have to disconnect anything. just removed my shock first, then pried down axle removed old coil, pried down even further to get new coil in, then replaced shock with a newer longer one. then i was done, haha, very simple preocess with no snags along the way

 

im guessing im going to have to redo my leveling kit if i do this? or can i just add another leaf in the back to lvl it out
