Be careful when lifting a longbody (post 2000) above 3", you will end up with some serious driveshaft vibration caused by the altered rear geometry (different amount and set up to the shorty's).

I ended up using Toughdog adjustable Hilux front torque rods x 2 for the upper links, with custom metal inserts pressed into the urethane rubbers to correct (tilt back) the pinion angle. Too much rear tilt will foul the rear shock near the lower diff mount.
