Want to replace the rear shocks on my fx4. I have the 3" blocks in the back (and the front leveling kit, for what's its worth) and iv seen and heard a lot of people replacing the shocks when they put bigger blocks in. And I can feel the truck is a little bouncier, so what shocks should I go with. Thinkin either the bilsteins or fox or rancho replacements. Any other opinions?
