FMVSS No.126 compliant

The NHTSA's Federal Motor Vehicle Safety Standard (FMVSS) No.126 requires all new passenger vehicles to include Electronic Stability Control (ESC) systems that meet certain standards that can be tested through a comprehensive series of evasive maneuvers. Aftermarket products must meet these standards as well.

Zone Offroad Products is leading the industry by independently testing all suspension kits to verify the kits are fully compliant with the stability control system requirements set by Federal Motor Vehicle Safety Standard (FMVSS) No. 126.

Featured Technology & Benefits

  • Coil springs designed to give a full 4" of lift while maintaining a factory style ride. Our coils are 2door/4door specific, so be sure to select the proper application.
  • A front adjustable track bar is included to properly center the front axle
  • Cam washers are included to correct front end alignment
  • Rear extended sway bar links are included. These links come with urethane bushings to increase performance and reduce body roll. The factory rear links are then used in the front.
  • A rear track bar relocation system is included to perfectly center the axle under your JK
  • 2" bump stop extensions are included to protect your vehicle while still increasing wheel travel
  • Brake line relocation brackets are supplied to allow for the dramatic increase in wheel travel
  • New Zone front and rear shocks are included that are valved specifically for your JK

Prepare yourself for the perfect combination of off road performance and on road handling. This 4" JK system offers dramatic improvement in both ground clearance as well as wheel travel. With 4" of lift, you can clear those 35's with tons of room to twist as well as use your Jeep for a daily driver. Zone coil springs are designed so they can be totally smashed flat and still return to their original height, so you don't have to worry about your coils sagging!

A heavy duty adjustable front track bar is included with durometer specific urethane bushings as well as a rear track bar relocation system. Unique to Zone, this system comes with front cam locks to increase caster and ensure good handling characteristics. These cam locks are guaranteed not to slip out of position like other adjustable round cam designs can.

Top this all off with extreme travel custom valved shocks and you have a system that will not only get you through the trail, but will handle just as well as a daily driver.

JKS Flex Connect *Disconnecting* 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. Featuring our popular quick disconnect style pins, this Flex Connect link kit can be disconnected like a normal sway bar disconnect for the extra tough trails.
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.


Optional Performance Spring Kit Includes (Available Seperately Below: 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.
