I'm fairly sure from looking at pics that you keep both the stock tierod AND draglink - and Calmini just gives you a little extender/adapter that lets you hook up the draglink to the factory Nissan pitman arm (Note: I do know that the kit HAS to connect to a factory Nissan pitman arm. If you have the pitman from the Calmini steering system you have to switch it back out for the stock one).

I'll probably buy/make a heavy duty tierod/draglink at some point - but for starters I'll stay Jeep stock.

Thanks for the tips, Brian! Someone pointed me at the N4W thread about the trackbar and it sounds like Calmini is putting misalignment spacers in the kits now - but I'll double check.
