I emailed JKS manufacturing http://www.jksmfg.com/ about a Quick Disconnect for the liberty and this is the response i get:

Claudio,
Sorry for the delayed response....I was on vacation last week.

I do have some "Quicker Disconnects" on the company KJ. We have been running them all winter. We have yet to come up with a great way to hold them out of the way when disconnected. I should have something for market in the next couple months.
Best Regards,

Every one have his own look on the disco, on a Nissan Terrano II (sadly never get to USA that beaty) i own before with IFS and 4" Trailmaster lift i run all the time with the sway bar disconnected and all i can say you can feel is disconected in street turns, on the road passing others vehicles you can't feel it.

Be nice to get some pictures of this. Many people on this board do not like the idea of quick dicos b/c the kj needs thats front sway bar alot more than a solid axle would.

I would really love to see some disco's. I'm getting tired of pulling off the sway bar every time I go wheeling. Especially in the cold. Personally I don't have any problem with the say bar off either Claudio. Definitely more body roll, but its fine if you know what to expect and don't plan on cruising at high speeds. Plus it definitely helps make things more stable when wheeling. I would really like some disco's if they where available.
