The adjustables are all valved the same - they have a pretty wide adjustment range though. Actually, I believe I can request custom valving in them, but it takes forever. I used to get them to specially valve their hotrod shocks for me, but they were the non-adjustables.
I'm not sure on the exact price, I can beat summit by a couple bucks, but more importantly, I always modify the Afcos to fit in the stock shock mounts.
