Great looking truck.
BDS suspensions has a 4 link conversions for those trucks that can be used on a stock height (it does increase the caster slightly, which isn't a bad thing on a 05+ front suspension). It will increase the travel considerably and maintain the proper geometry throughout the suspension travel, which the stock arms do not.
By the way, I have a FWC and love the fact that offroad, it does not affect the feel of the truck. Mine is a shell, so it is really light, but overall you can't tell it's there even in the off camber sections.
