I bought the Mancini kit, they are the same as the Mopar one. The kit is very basic, a couple of boxes (which you could actually make yourself) and a rear shacke kit along with a couple of spring perches. I drilled the boxes in three places so I can move the springs up or down one inch from the stock location. I just ordered the AFCO leaf spring sliders from Mancini as well. Mancini ships very fast, I also live in Canada and I get my stuff shipped to a shipping and receiving place in Sumas WA, then I drive down to pick it up. If you ship directly to Canada your stuff can be held at the border for several weeks until it clears customs.
