The JSPEC™ J Konnect 3.5” suspension system is for the JK Wrangler owner who wants it all; the culmination of our expertise in creating suspensions for the JK that accentuate the JK Wrangler’s strengths while addressing its weaknesses. By combining some of our best known off road ready upgrades with our popular daily driver friendly modifications, the J Konnect will transform your JK into the commuter that you aren’t afraid to wheel! This system includes our simple and nearly indestructible J Link control arms and our JSPEC™ specific front and rear track bar brace combination that assures your Jeep drives out of whatever it gets in to. Our draglink flip flattens the steering linkage and track bar, relieving pressure on the steering box associated with lifting a Jeep and eliminating bump steer. The J Konnect system is still the quickest, easiest installation of its kind, but does feature a couple of key components that require welding. Upgrades for the J Konnect include some of JKS’s well known, hardcore off road upgrades that require the expertise of an experienced installer.
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 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 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.
JKS J-Link Control Arms
- Superior strength compared to OEM control arms and can be used with OEM upper control arms.
- Formed to match the factory front arm profile, creating plenty of clearance for over-sized tires.
- Made from 2" x 1/4" wall DOM tubing.
- Premium Clevite® brand rubber bushings absorb noise and reduce vibrations for a quiet, comfortable ride.
- Durable Powder Coat finish provides excellent protection from corrosion and debris.
JKS Front & Rear Track Bar Mount Support
Anybody who has spent trail time around a JK knows the track bar mounts may very well be the first weak link to give way under heavy off-road use. The addition of weld-on front and rear track bar gussets working together with the multi-mount-point JKS track bar relocation brackets makes the weak factory mounts nearly indestructible. Yes they are weld-on but that is the key to making them strong. Plus, it is easier to weld our gussets on in the shop versus trying to weld a broken factory bracket on the trail.
JKS Drag Link Flip + Front Track Bar Bracket
The JSPEC™ drag link flip flattens out the steering angles when combined with the lift heights of 2” and above providing better performing, more solid steering feel over the factory setup. The JSPEC™ drag link directly replaces the factory link and uses the factory adjusting collar and tie rod end at the pitman arm. This installation requires drilling out the steering arm tapered hole in the passenger’s side knuckle and installing a precision machined tapered insert. We even included a 7/8” step bit to make this process easy and not require the purchase of an expensive drill bit to complete the install. The new insert has a knurled outer surface and has a slight interference fit making it extremely strong and eliminates any possibility of play or loosening. The insert can also be reused in the opposite position if the Jeep ever needed to be returned to the original steering setup. To properly compliment the new steering angles provided by the drag link flip, a front track bar bracket is supplied. The new bracket mounts to the factory track bar axle mount. It not only adapts the factory mount for proper track bar angles, it also strengthens the factory setup by tying into the axle via a u-bolt setup integrated into the design. The new track bar location mimics the drag link angle perfectly and eliminates bump steer.
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.
