The Flex Connect is a huge leap forward from a traditional sway bar link. With the specially turned PAC springs, the link is able to extend and compress, working with the factory sway bar to control body roll. The Flex Connect improves the way the stock bar absorbs imperfections in the road (or offroad surface) by soaking up head bobble inducing bumps. The Flex Connect also improves the articulation of the JK suspension over the stock setup. The Flex Connect springs compress and extend under load, giving the same effect as if the sway bar was twisting further and allowing the suspension to articulate more. Works on JK and JK Rubicon front sway bar only. Works with 2-5in of lift. Will work with aftermarket JK sway bars but may require additional mouting modifications.
