Flex Connect Sway Bar Link Kit | JK Wrangler | *PATENT PENDING*


Flex Connect Link Kit

  • JKS Flex Connect Link Kit and Flex Connect Performance Spring Kit for Jeep Wrangler JK w/ 2" - 5” of lift. 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.

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.

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
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.

I just purchased an installed a set of flex links and have to say I am disappointed. they do look great and are well made but I got zero improvement in how my 2014 jkur with 2.5"lift felt. Maybe it is because my set up prior was so good and drove so well but I literally got 0 improvement on normal rough roads. I have not tried it offroad yet. I wonder if it makes more impact on a 2 door vs a 4 door. Definitely not worth $299. I have used both jks quick discos and adjust sway bar links and those were/are great products. the discos have over 50,000 miles and bushings still going strong. So not that I don't like jks these are just not what I was hoping for.

This is the second time I have tried to write a review on te flexlink. The first one was not published. I doubt this one will be either.
In my first review I complained that the standard spring that the flex links are shipped with are too stiff and provided no improvement over stock. I did get the spring pack kit and want to report that the Yellow spring should in fact be shipped as stock spring. with the Yellow spring it works great on washboard dirt roads at speed and takes the sharp edge off. I travel twisty pavement a lot and found no downside using the Yellow spring and also performed some evasive type maneuvers and there was no loss of control. With the Yellow springs standard I would say this is a top notch product and worth the price. If it came this way I would give it 5 stars. Give the customer a choice.

Like many non-rubicon Jeep owners, disconnnecting is a pain. I used to have the TF quick disconnects and got tired of disconnecting. While researching alternatives like Currie Antirock, I came across this product, the FlexConnect.

Install took 30min? Very easy.

The one thing that swayed me away from Antirock was that you're pretty much stuck with articulation all. the. time. - wasn't sure if I would've liked it driving at highway speeds and cornering. With the FlexConnect, I drove with the RED springs for a while but I prefer the plushier ride of the YELLOW springs for daily driving and would swap out to the BLUE springs on the trail. And for the most part, the BLUE springs performed ok. And the good part is that if I'm tired after the trail run, I'll just go home on the blue springs and swap them out later...

I've done most of the harder trails in SoCal using the BLUE springs without much issues. But there are times when one my rear wheels would lift higher than others over an obstacle that are fully disconnected. I had a bit of a scary instance on Pinyon canyon trail in Anza Borrego at the "Heart Attack Hill" where the initial drop lifted one of the rear wheel about 4' in the air. This did not happen to anyone else on the run. Next time, I'll need to fully disconnect to prevent it -which is a bummer.

If you're the overlanding and light trail type, I highly suggest this product as it smooths everything but still have a feeling of control at higher speed on washboards, etc. But for crawling, unfortunately, it's far from perfect. I really wanted to like this setup.

The other issue I have is the quick disconnect post that is attached to the swaybar, the threaded end is a tad too long and is taking chunks out from the steel coil mount shroud every time the Jeep shifts weight from one side to the other. It's barely noticeable on the road but on the trail, it's quite annoying to hear metal on metal scrapes.
