JKS Adjustable Control Arms for JK Wrangler, TJ Wrangler, XJ Cherokee, ZJ Grand Cherokee, & WJ Grand Cherokee

JKS's lower control arms are 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 our 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. With over 3 inches of adjustment, adjusting 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 lower 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.  By the way, I'm not the only guy impressed with the JKS arms...check out THIS ARTICLE from Tony Curless from 4wd and SUV magazine, who is one of the original ZJ modifiers, from even before my day, lol.  His articles on "The Rise and Fall of Project ZJ" were one of the things that got me into modifying *MY* ZJ, and the rest is history...but I digress.

Black powder coating and zinc plating are standard.

JKS's 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 front upper control arms utilize an exclusive modular design only available from JKS. 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...
