cranky, offroading is not listed as an activity that excludes the warranty, as such.. go for it.

tj, I don't know which will last longer, but if/when the ranchos fail, it will cost you shipping for replacements, with the bilstiens it will cost you shipping + the cost of the shocks..

I am a fan of the 9000's due ot the fact that you can change the valving as you see fit. I tend to run stiff valving in the sand, to reduce the chances of bottoming out, super soft everywhere else offroad, to keep the tires on the ground, and somewhere in between for daily driving. It is nice to be able to stiffen the rear end when I am loaded, and soften it when I am not..
