I've got a 2001 f150, and I'm gonna run a reservoir shock under the bed in the stock location, my question is what size shock will bolt right in (8",10"...etc), and how much travel am I capable of getting?(oh,l i'm also running a set of deavers) . Or is it worth it to build a subframe higher up right under the bed and mount the shock higher up. Any suggestions are appreciated. Thanks in advance...
