About Us

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.
