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.
JSpec Front and Rear Shocks
A great set of coil springs are useless unless you have a set of shocks to control them. When looking at the TJ market, we wanted to be able to provide a shock that capitalizes on the JSpec springs ride characteristics without breaking the bank, so we created the JSpec Gas shocks. The JSpec shocks are valved specifically to work with the JSpec dual rate springs, giving maximum performance in the widest variety of terrains.

JKS Adjustable Front Track Bar
When you think of adjustable Jeep track bars you think JKS. For years, Jeepers 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 the JSpec TJ suspension systems. The adjustable track bar dwarfs the factory component, offering fine adjustability of the front axle position to compensate for the additional lift height provided by the JSpec coil springs. Factory style rubber bushings are used at the axle end of the bar for quiet and compliant function and our own spherical misalignment joint on the frame side for the best combination street ride and off road performance. The 1-1/4"-12 threaded adjustable end provides fine-tune adjustability and superior strength when combined with the 1-1/2" x 1/2" wall DOM tube, CNC formed track bar. Adding an adjustable track bar versus a relocation bracket also keeps the TJs steering angles in-phase to provide great handling and keep bump steer in check.
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.
Front Brake Line Relocation
How much can you say about brake line relocation? Well, it is a necessity anytime a TJ is lifted, 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 TJ 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 Suspension System. The result is just enough length at full axle droop with minimal modifications to the factory routing. And just as a reminder of where you they came from, the rear brackets get treated the famous 'JKS' oval logo sticker.
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 treated with a track bar relocation bracket. 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 helps with handling and body roll.
Rear Bump Stop Extensions
The front, like brake line relocation brackets, are another component set that usually doesn't get much attention with most lift "kits" on the market. The bump stop extensions in the TJ JSpec suspension systems were made specifically to maximize suspension travel while maintaining save compression limits for both the coil springs and shocks.
A major downfall with most 2 TJ lift kits is the lack of castor adjustment. This good enough philosophy lends itself to a Jeep that is twitchy and darts all over the road. This is why weve chosen to include eccentric alignment cam bolts which completely replace the factory hardware, allowing for fine-tuning of the caster settings.
TJ factory control arms perform very well, but dont hold up well to extreme abuse. If youre a wheeler we highly recommend upgrading to our J Link lower control arms for the ultimate simple, durable suspension set up while maintaining factory ride quality.
