The remote reservoirs are pretty damn nice to have and definitely improve ride quality.I run bilstein 7100s with my OMEs. Way better ride than OME shocks, but I've custom tuned the valvestacks. For a relatively stock truck 255/70 valving would be the best starting point. I add a little bit more compression valving in the high speed section of my 255/70s up front. I think that the rebound up front could also use a little more in the medium speed section. In the back I'm running 275/60, which needs a little less rebound.
I used 8" remote resevoir versions with rubber adapter bushing. Others have used 10" short body, which might be available with a stud mount that works with our upper front frame mounts. In my case I cut the stock stud mount off and welded on a modified (shortened) Ford F250 mount.
