The JSPEC™ JKontrol systems take the off road capable daily driver to the next level, bringing JKS's off road expertise to urban maneuvers. The J Kontrol system contains JKS's beefy control arm relocation brackets with an OEM style draglink flip kit for the ultimate combination of durability, road comfort and unrivalled street handling. We took the time to recreate the idea of a control arm bracket that not only flattens the front control arm angles and corrects alignment, but meets JKS high standards as a durable, high quality component that can take a beating off road. The draglink flip kit levels the draglink, completely eliminating any hint of bump steer and has a clean, easy installation with an OEM fit and finish. As with any JSPEC™ system, J Kontrol systems are fully customizable to meet your needs.

Front and Rear Dual Rate Coil Springs
At the heart of any true Jeep® suspension system are properly designed coil springs. Not everyone uses their Jeep® for the same purposes, therefore you need a system that adapts to different terrains both on and offroad. By developing tuned sets of dual rate coils springs, JSPEC™ coils provide the best performance in any situation. Whether loaded down with gear for a weeklong expedition, running light for some rock-crawling fun or loaded with a few friends for a trip to the beach, JSPEC™ coils will provide the ride you want and the performance you need.
Fox 2.0 Adventure Series Front and Rear Shocks
A great set of coil springs is useless unless you have a set of shocks to control them. When developing a shock to work in harmony with the JSPEC™ coil springs we went with the best, FOX. The Fox 2.0 Adventure Series shocks provide a quality ride and complete control no matter what terrain you tackle. The IFP (internal floating piston) design keeps the high-performance shock oil separated from the 200 psi nitrogen gas charge. This separation provided by the IFP eliminates oil aeration, to allow longer fade-free dampening performance. Paired with the set of JSPEC™ dual rate coil springs these shocks offer impressive performance and the adaptability to handle any terrain.
JKS Front Sway Bar Quicker Disconnects
The flag-ship JKS Manufacturing product is the Quicker Disconnect. JKS was the originator of the sway bar disconnect concept. That original concept was perfected with the Quicker Disconnect design which still remains the best sway bar disconnect on the market today. Adjustable length and greasable with JKS-exclusive poly-flex ball, high-misalignment ends, the Quicker Disconnect is everything you want in a sway bar disconnect. Stainless steel mounting studs provide an anchoring point for each end of the links and allow for easy removal and installation. For JK Rubicon owners, additional hardware is included to bolt the swaybar link and allow you to take advantage of the benefits of these links while retaining the function of your factory installed electronic disconnecting swaybar system.
Front and Rear Brake Line Relocation
How much can you say about brake line relocation? Well, it is a necessity anytime a JK is lifted much over 2", especially with longer travel shocks. In most kits on the market these items are an after-thought, but not in the JSPEC™ kits. The JKS brake line brackets included in the JK JSPEC™ suspension systems utilize the factory brake line mounting holes and locating tabs. This ensures that the brackets won't rotate and eventually come loose. The brackets were designed specifically to work with the shock lengths used with each JSPEC™ system. The result is just enough length at full axle droop with minimal modifications to the factory routing.
Front and Rear Bump Stop Extensions
The front and rear bump stop extensions, like brake line relocation brackets, are another component that usually doesn't get much attention with most lift "kits" on the market. The bump stop extensions in the JK JSPEC™ suspension systems were made specifically to maximize suspension travel while maintaining safe compression limits for both the coil springs and Fox 2.0 shocks. The front extensions are made from 2-3/4" billet aluminum while the rear extensions are made from heavy-wall steel rectangular tube. Both sets fasten directly to the axle and are made to hold up to the abuse your new JSPEC™ equipped JK is now built to handle.
- Rear Trackbar Brace [JKS PN: OGS169] is strongly recommended to reinforce weak factory mount on axle.
- Max. Recommended Tire Size 35x12.50 on 16x8 wheels with 4.5" backspacing
