Now I have the longer shocks & relocated brake lines I have been down to the tunnel access to our fields to test the flex out.
Spec is:
+2.5″ HD OME springs (gave 3″ lift
+2″ coil spacers at the front & +2″ shackles at the rear
+3″ Rough Country shocks (+2″ BPEs at the rear, not fitted at the front yet)
JSK arb disconnects

Need to get hold of some cranked front lower control arms as they are limiting front flex by binding on the axle mounts at the moment.
