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.
Say hello to J-Rated. A visual terrain scale and collection of suspension systems that take the guesswork out of building your Jeep’s chassis. It’s like asking a JKS suspension tech to join you on your next Jeep adventure. They could ride along and evaluate your Jeep’s performance. With that knowledge, that same JKS rep could point you towards the ideal lift kit for the way you drive your Jeep. JKS has done just that its new J-Rated Terrain Scale and complete suspension packages.
