You must be talking about Sway bar disconnect
disconnect it will give you more flexibility offroad.
The underbody armor of JEEP is ok for mild action. But it does not hold well
against big rock. My underbody is a mess already and I am going to install river raider
armor.
Anyway, that's a cool event. I wish I can live closer to mountain. Here in South
florida, we have to travel at least 4 hours to get some real rock to crawl.
