On the Xterra with a Shrock, winch with synthetic line and the sway bar off the 600 was rather bouncy, but I got a good deal on 650lb springs and with them on the front is tighter than it was with the 600 and sway bar. I think the 700 would have been overkill for my setup and I do have the steel rear tire carrier and full skids and sliders, so it is about as heavy as I can get it.
