How's this (in increasing severity):
1. Longer springs / coil spacers / wind up torsion bars, trim bump stops
2. New shocks (with longer travel, if that has been limiting things)
3. Diff lock / aftermarket diff & CV's (stronger)
4. Lower diff (spacers??)
5. Aftermarket control arms (some sort of kit???)
6. And finally, SAS (Ha, beat you to it!)
