Flex Connect Disconnecting Sway Bar Link System | WJ Grand Cherokee | *PATENT PENDING*


WJ Flex Connect Link Kit

  • The Flex Connect is unlike any other sway bar link on the market today. Developed jointly with PAC Racing Springs, this patent pending design creates a dual-rate sway bar system when used with the factory or aftermarket sway bar. PAC Racing Springs designed the Flex Connect springs to handle hundreds of thousands of cycles and maintain maximum performance. These springs are housed in a precision machined aluminum body and utilize a steel alloy link rod. The attention to design details stretches to the ends where the industry famous JKS spherical sway bar link bushings are installed in greaseable aluminum ends. The aluminum link is anodized for long term good looks and corrosion resistance.
  • This system uses the same, patent pending, link design as the popular JK kit allowing for tunable roll resistance when combined with the additional Flex Connect Performance Springs. For the WJ, the link system mounting kit includes JKS disconnect pins making the links disconnect-able. This will allow for maximum articulation when needed. It also makes it easy to remove the Flex Connect link when a spring change is in order.

Flex Connect sway bar end links are a huge leap forward from traditional designs. Designed for JeepWJ Grand Cherokee, Flex Connect features spring-loaded end links that extend and compress. Flex Connect controls body roll while also improving articulation. Flex Connect is now available with disconnecting hardware to create the ultimate offroad sway bar link upgrade. Flex Connect improves the way the stock bar absorbs imperfections in the road (or offroad surface) by soaking up “head bobble” inducing bumps. The springs inside Flex Connect end links compress and extend under load, giving the same effect as if the sway bar was twisting further and allowing the suspension to articulate more.

For those looking to get the ultimate performance out of Flex Connect links, JKS offers an optional Performance Spring Kit that allows you to tune for roll stiffness. Adjust 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. Each spring's specs and functions are detailed. This is a guide to get started adjusting the roll stiffness of the Flex Connect system.

Flex Connect Kit Base Spring
OE Spring (Pre-installed in the Flex Connect)
- Effective spring rate is 35% softer than factory, 1.1” total link travel
- Closest spring to a stock fixed length sway bar link. Maintains road manners while still giving the benefit of absorbing the “head-bobble” type bumps
- Changes your stock sway bar system into a dual rate system.

Performance Spring Kit Includes (Available Seperately) PN 2100
Red Spring (Road)
- Effective spring rate is 45% softer than factory, 1.3” total link travel
- High Rate/Low Travel
- For those looking to maintain on road manners but gain a little more Flex Connect travel and forgiveness over the preinstalled OE spring. Also a great choice to higher speed offroad situations
Yellow Spring (Trail)
- Effective spring rate is 60% softer than factory, 1.6” total link travel
- Mid Rate/Mid Travel
- For those looking to venture off the trail for mild offroading at moderate speeds
Blue Spring (Crawl)
- Effective spring rate is 75% softer than factory, 2.3” total link travel
- Low Rate/High Travel
- For playing in the rocks and off-camber situation. Gives more suspension articulation then a stand link/sway bar setup while maintaining the stability of the sway bar.
