Since 1989, JKS Manufacturing has developed some of the world’s most widely used and respected products for Jeep® vehicles. It all started when they pioneered the original Quick Disconnect™ brand of quick-release swaybar disconnects. Since then their product range has expanded to include such favorites as the ACOS™ line of height-adjustable coil spring spacers, and perhaps our most advanced creation to date, the variable-rate SwitchBlade™ Swaybar System.
JKS is proud of the fact that they continue to manufacture all of their products in the USA, using only premium grade materials and state-of-the-art machinery. You can always rely on JKS products to provide unquestionable benefits to vehicle performance. From cushioning hard suspension impacts off-road, to restoring the geometry of your suspension for safer and more predictable handling on-road, our products improve the experience of owning and operating a Jeep vehicle.
Because JKS products take advantage of Original Equipment components and technology whenever possible, vehicle drivability and reliability are not compromised. Discover why recreational and competitive Jeep enthusiasts around the world insist upon JKS products to improve vehicle performance, reliability and versatility. It's no coincidence that those who know Jeep performance best choose JKS products for their own vehicles.
JKS Manufacturing adds to its lineup of suspension upgrades for the Jeep Wrangler JL and Gladiator JT with new J-Flex front adjustable upper control arms.

At the frame mount a forged end is threaded in allowing plenty of adjustability for use with with a wide range of ride heights from stock to 6″ of lift. The forged ends allow 15 degrees of articulation in either direction and can be easily serviced at the grease fitting. These arms come fully assembled right out of the box finished in a gloss black powdercoat. Upgrade your JL/JT front upper control arms with JKS Manufacturing.
