Front and Rear Dual Rate Coil Springs:
At the heart of any true Jeep suspension system is properly designed coil springs. Not everyone uses their Jeep for the same purposes. That's why it's important to utilize a system capable of adapting to different terrains both on and off the road. By developing tuned sets of dual rate coils springs, JSPEC coils provide the best performance in any situation. Regardless of whether you are running light for a rock-crawling adventure, packed heavily with gear for a weeklong expedition or loaded with a few friends for a quick trip to the beach, JSPEC coils will give you 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, JKS went with the best, FOX. The FOX 2.0 Adventure Series shocks provide a quality ride and complete control no matter what kind of terrain you are tackling. 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 superior performance and the adaptability to handle any terrain.

JKS Adjustable Front Track Bar
When you think of adjustable Jeep track bars you think JKS. For years, Jeep owners the world over have trusted JKS adjustable track bars for their strength, fit, function and durability. For those reasons it is a no-brainer that a JKS front adjustable track bar be an integral part of all JSPEC JK suspension systems. The JKS adjustable track bar dwarfs the factory unit using durometer specific rubber bushings at each end of the bar for smooth, quiet operation. The 1-1/4"-12 threaded adjustable end provides fine-tune adjustability and superior strength when combined with the 1-1/2" x 3/8" wall DOM tube, CNC formed track bar. Adding an adjustable track bar versus a relocation bracket also keeps the JKs steering angles in-phase to provide great handling and keep bump steer in check.

JKS Front Sway Bar Quicker Disconnects
The flagship 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 sway bar link and allow you to take advantage of the benefits of these links while retaining the function of your factory installed electronic disconnecting sway bar system.

Front and Rear Brake Line Relocation
Bake line relocation 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 are 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.

Rear Track Bar Bracket
As with the front suspension, the rear requires modification to the factory track bar setup to compensate for the new ride height. While the front gets a new track bar, the rear is adjusted with a track bar relocation bracket. The relocation bracket was chosen here for a several reasons. First, by raising the track bar mount position at the axle we flatten the track bar angle and make a slight adjustment to the roll-center height, which improves handling and body roll. Second, the new track bar relocation bracket doubles as a factory axle bracket brace. The factory rear axle track bar mount has been a known weak link since the JK was first built in 2007. By making the new relocation bracket out of heavy-duty 3/16" steel and bracing directly to the axle tube, the factory bracket is reinforced and up to the task of handling the new lifted height of the JSPEC suspension system.

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 are 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.

Tech Tip: JSPEC suspension systems are also the perfect starting point for the off roader who wants to customize their JSPEC-equipped JK Wrangler with a modular design that can be upgraded with JKS control arms, brackets, steering upgrades, braces, gussets and speed bumps to tailor your Jeep’s performance to your needs.
