See Why JKS MFG Control Arms Are So Much Better Than Your Jeep’s Stock Arms

While the coil suspension in Jeep Wranglers, Cherokees, and Grand Cherokees offers far more articulation than the leaf springs of earlier Jeeps, there is still plenty of room for improvement. The factory control arms are relatively short and use rubber bushings at each end of the stamped sheetmetal arms. These components are adequate when they are new and under a stock Jeep, but time, mileage, and larger tires are never kind to the factory control arms. Add a lift kit to throw the factory geometry out of whack and the stock arms become woefully inadequate where the caster and pinion angles are concerned.

Fortunately, JKS Manufacturing has a solution to all of these issues with a complete line of control arms for the full alphabet soup of Jeeps, from TJs, XJs, MJs, ZJs, and WJs to JKs and JLs.

Our 2006 Wrangler TJ Unlimited (aka LJ) had 3-inch-lift springs but factory control arms. In addition to wandering going down the road due to inadequate caster, the arms had began to clunk after years of abuse on the trail. We replaced all of the arms with new J-Flex units from JKS Manufacturing just in time for a 1,600-mile road trip for the Easter Jeep Safari. The arms made the Jeep so much easier to drive down the freeway at 75 mph, and we didn't have to worry about abusing them on the notorious red rocks of Moab. That's what we call a win-win.
