It's been about 80k miles and plenty of rocks and other things smashing my shocks (RS5000's). I am not sure any of them even have any fluid left in them. I was debating getting some RS9000 but I was never crazy about Ranchos and I have heard great things about Bilstiens. So I got four (no need for two on the front) 5100's on the way for $75 a pop with free shipping. Not a bad deal if you ask me. Just thought I would post up as I have not done much to the Bronco lately. Can't wait to see how it rides.
