Over the years the engineers at JKS Manufacturing have continually developed cutting edge new products allowing Jeep owners to get the most out of their vehicles. Innovations beginning with the original sway bar quick disconnect back in 1989 leading up to ACOS adjustable coil spacers and J-Axis control arms have kept JKS on the forefront of aftermarket Jeep engineering. We are excited to announce the latest product to hit the market from JKS Manufacturing is the Flex Connect sway bar link system. The Flex Connect is a huge leap forward in suspension technology allowing the Jeeps factory sway bar to be transformed into a high performance sway bar for optimal vehicle performance on street and trail. The design uses a specially engineered adjustable sway bar link that houses a pair of small coil springs that allow it extend and compress under load to better control body roll as well as absorb imperfections in any terrain. Additionally the Flex Connect increases the vehicle articulation over using a standard sway bar link and is easily customizable to meet your driving need using varying rate springs.

The Flex Connect was designed in conjunction with Pac Racing Springs following extensive performance and durability testing to bring this patent pending off-road racing technology into the Jeep world with a bolt-on sway bar system specifically tuned for the popular Jeep Wrangler JK vehicles with other applications soon to follow. Construction of the Flex Connect is second to none with the link ends machined from 6061 aluminum utilizing JKS spherical bushings for bind-free performance throughout articulation. The ends include grease fitting for quiet operation and easy servicing. The machined body of the Flex Connect houses the springs and piston all secured with a removable cap to keep out contaminants. The standard kit included one Flex Connect link, one standard link and hardware to complete the install.

The Flex Connect is customizable to meet your driving needs. Along with the standard spring set that is included with the Flex Connect, JKS offers 3 spring sets that can be mixed and matched to tune the vehicles roll stiffness, all of which can be installed in a matter of minutes using the supplied spanner wrenches whether you’re in the driveway or at the trailhead. The red springs are a high rate/low travel spring for ideal for on-road driving. The yellow “trail” springs are a mid rate/mid travel design offering optimal on/off-road performance. The blue “crawl” springs use a low rate with maximum travel to enhance suspension articulation while maintaining off-camber stability.

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 

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.

The initial Flex Connect launch is designed for Jeep Wrangler and Wrangler Unlimited JK vehicles with 2-5’’ of suspension lift. Additional kits will be available in the near future. Take your Jeep to the next level of performance with JKS Manufacturing and the new Flex Connect sway bar link system.
