I bought from Source Engineering-they have bilstiens that are special made for our coaches( they actually change the valving in the shocks to give better control and ride. They have front and rear sway bars along with additional pieces for our Monacos. I changed my shocks without removing the wheels. There is a tool made to hold the top of the shock shaft while you tighten the nut but I couldn't find one so I made a tool to fit. I took a 8mm open-end wrench, heated red hot and bent it 90 degrees-made the job doable-good luck
