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 off-road 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.Â For those looking to get the ultimate performance out of the Flex Connect link, the optional Performance Spring Kit allows for roll stiffness to be adjusted using one of the 3 unique replacement spring sets. These springs are tuned to work in different terrains or vehicle setups. The Performance Spring kit includes tools and instructions to swap out the pre-installed OE springs with any of the 3 optional spring sets. Choices can be made based on terrain or even how the Jeep is equipped for a particular trip. As the spring set rates get softer they have more travel, increasing the suspensions ability to articulate. Below, each spring spec and function is detailed. This is a guide to get started adjusting the roll stiffness of the Flex Connect system. Flex Connect Kit Base Spring
