Since 1989, JKS Manufacturing has developed some of the world’s most widely used and respected products for Jeep® vehicles. It all started when we pioneered the original Quick Disconnect™ brand of quick-release sway bar disconnects. Since then our 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, J-Spec Suspension systems including the JK Front Coilover Conversion.
Proudly Made in USA
We are proud of the fact that we continue to manufacture all of our products right here 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.
And 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.
