I don't have the Rancho 9000x myself, but I seem to recall other posts saying the shock quality and adjustability is great. I also remember reading that the in-cab compressor based adjuster is an expensive install, and hard to get working correctly.

So I think the verdict was, get the shocks, but adjust them at the shock directly rather than go with the in-cab adjustment. But it's also very cool when the in-cab adjustment does work.

Do a search of the forum. Those Rancho shocks have definitely come up in the past.
