1 The JT utilizes a similar front 4-link design to the current Wrangler JL. JKS has developed special
dual rate coil spring options to maximize performance and capability. A set of FOX 2.0 performance
series IFP gas shocks are paired to these coil springs for optimal performance and ride quality for
on/off-road driving. The stock track bar is upgraded to a stout JKS heavy duty 1-1/2” OD x 3/8”
thick adjustable track bar to properly recenter the front axle. JKS quicker sway bar disconnects are
supplied for the front allowing strength, adjustment, and the ability to easily disconnect the sway
bars. Billet aluminum CNC-machined bump stop extensions are supplied along with brake line
brackets and J-Link lower control arms to improve strength and correct caster. This setup offers stellar
performance on the trail while providing the comfort and handling owners expect.
2 The new JL/JT outperforms all previous Jeeps in so many ways, but there’s always room for
improvement. In place of the factory lower control arms JKS supplies the J-Link arms, built from
2” OD x .250”-wall DOM tubing, formed inward for improved tire clearance and featuring Cleavite
rubber bushings for quiet operation, long life and maintenance-free operation. The longer design
corrects caster for up to 4.5” lift kits and the heavy wall design is built to take any abuse you can
throw at it out on the trail.
3 The rear suspension features several new and unique features. The rear of this Jspec Jrated
system includes dual rate coils to maintain ride quality without losing tow capacity. Adjustable sway
bar end links, a heavy duty track bar bracket, brake line brackets, and a matching set of FOX 2.0
shocks round out the rear for a level stance that pairs perfectly with the front.517-278-1226 JKSmfg.com
D 467A LOOK AT JKS’S NEW 3” JSPEC
JRATED SYSTEM FOR THE 2020
GLADIATOR JT
The long awaited new Jeep truck is here and
right out the gate it has an impressive sell sheet,
class leading payload numbers, ample power
numbers, offroad capability and unique features
like the removable roof. It’s safe to say the new
Gladiator is making waves in the offroad market
and customers get it. While there are some
similarities to the current Wrangler JL in the front
suspension, the rear is all new with longer control
arms and progressive rate coils that resemble more
of the RAM 1500 rear suspension. The truck is
capable right off the showroom floor, but its only a
matter of time before the aftermarket gets their
hands on it to up the ante, providing more
performance, more capability, and all the other
add-on accessories that come with owning a Jeep.
With keys in hand we turned to our friends at JKS
Manufacturing in Coldwater, MI to take a look at
their newly released 3” Jspec suspension system to
get the inside scoop on what it takes to lift the new
Gladiator to fit 35-37” tires. JKS Mfg is no
stranger to engineering parts for Jeep vehicles,
they’ve been at this for 30 years designing
solutions for Jeep vehicles.123ADVERTISEMENT
