JCR makes GREAT products, customer support is outstanding!. If you are installing them yourself, be prepared to pony-up for carbide drill bits. The pinch-welds you are going to have to drill through are harder than an ex-wife's heart! There are nut-tabs you are going to have to pass through the stamped frame rails, do yourself a favor and get some tac putty used to hang pictures on walls to hold them in place while you're wrestling with the skids, they are heavy and a little cumbersome. I think the side skids weigh-in at about 30#s each, front 25ish.
