I just installed the Rough Country lift in my 2009 Savana AWD van. I used everything in the kit but the rear shocks. I ended up using NAPA gas shocks off a 2500 van. The part number is NS 76763, and bolted right in. They are a couple of inches longer than the 1500 rear shocks. I have 285/70R17 Coopers on factory GMC alloy wheels and they fit great. I trimmed the rear edge of the front fender opening on the wheel well side, but I probably didn't need to. The cut isn't visible unless you look in the wheel well. They rub a little at full lock on the frame side. I think 295's would fit. The biggest thing is wheel offset.
