Complete box end wrench set and ratcheting box ends. Some would say, that's not 'special'. But take a peek at the box end set you have... a lot of the 'complete' sets skip the 18mm and you'll need that particular item (along with almost all the others sizes) for suspension stuff. Consider their SAE counterparts as well...the Jeep started out metric (mostly) but a lot of the aftermarket kits use SAE so the Jeeps are usually Chex mix.
