At the heart of any true Jeep suspension system are properly designed coil springs. By developing specially tuned sets of dual rate coils springs, JSPEC™ coils provide the best performance in any driving 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. Anticipating the desires of many in the JL community JKS has developed new HD dual rate springs offering smooth, predictable performance while offering extra capacity for customers adding front end accessories. Springs allow for 3” of lift in Rubicon models, 3.5” of lift on other models. Pairing to these coil springs you’ll have the option of Jspec gas charged twin tube shocks or FOX 2.0 performance series aluminum-bodied monotube shocks, both are designed for on-road comfort and improved capability when you hit the trail. Next up on the parts list is the JKS adjustable front track bar. Known for its strength and superior design, this track bar is built from 1.5” OD heavy wall DOM tubing. The track bar is formed for maximum clearance to the front axle, utilizing a threaded end with jam nut and durometer specific bushings at both ends to properly position the front axle while isolating NVHs. Also positioning the front axle is a set of lower control arm cam locks to correct caster for improved driveability.
When its time to hit the trail, the supplied sway bar quicker disconnects can be easily removed by pulling the clips and swinging the links up and out of the way for increased articulation. These sway bar disconnecting links maintain quiet on-road comfort and quiet operation using an adjustable design with spherical poly-flex ball bushings capable of high-misalignment. New for the JT quicker disconnects is a frame mounted retention bracket to secure your sway bar up out of the way when you’re on the trail. Along with sway bar disconnects to increase articulation, a pair of billet aluminum bump stop extensions are also included to control suspension up travel.
From the factory the Gladiator has a bit of rake, with the front end roughly 2” lower. To eliminate this rake while still maintaining ride quality and load capacity, a HD dual rate 1.5-2” lift coil springs specifically designed for the Gladiator were developed. Additionally extended length rear sway bar links are supplied to correct sway bar operating angle along with rear bump stop extensions to properly limit up travel. Rounding out the rear is your choice of matching Jspec gas shocks or FOX 2.0 performance series shocks to round out this package. Improve not only your new Gladiator JT’s appearance, but its offroad capability and on-road comfort with this new 3” J-Rated Jspec System from JKS Mfg.
