JKS Control Arms Help Stop Death Wobble!

The heaviest duty units on the market, bar none. Uni-body Jeeps tend to transfer more road noise and suspension vibrations than do Jeeps with solid frames, so JKS uses the factory OEM rubber bushing at both ends of their control arms to reduce those annoying noises and vibrations. These control arms twist or rotate while driving allowing the axle to flex easily over obstacles offroad, while keeping your suspension tight and in place on road, thus helping in the prevention of Death Wobble.  With over 3 inches of adjustment, making adjustments the length is as simple as removing one end and rotating the body or shaft to the desired length.

Thread strength can be thought of like axle spline strength, the more the axle splines there are, the stronger the axle is. JKS machines eighteen threads per inch on their control arms, not "acme" threads (typically five threads per inch) that tend to be weak and have very little fine-tuning ability that some of the other guys use.  The adjusting shaft rides on a full brass bushing and is then sealed to keep out dirt.  Each unit is then filled with grease to help keep out all moisture and maintain the threads.

JKS upper control arms are built to the same exact standards as their lower control arms.  Again, with over 3 inches of adjustment in pinion angle, these control arms can be fine tuned quickly and easily.  Factory OEM style rubber bushings are used at each end to eliminate as much vibration and noise as a stock control arm would...none of this urethane garbage that forces you to feel every bump.

The design is far superior in strength than anything else on the market, and can be completely disassembled and rebuilt with simple hand tools if required.
Simply the best control arms available...
