Is there anyone here using Bilsteins with an 8 ft slide in? I currently have Rancho 5000's on and suspect a couple are needing replacement. The 9000's are really pricey compared to the Bilsteins. I'm wondering if I should consider switching. I believe I have one front and one rear failing, so that means I need to get a full set. I will need to check them first just to be sure.
