JKS (www.jksmfg.com) has long been known for quality, innovative Jeep parts. From the Adjustable Coil Over Spacer (ACOS) to control arms, JKS offers something for every Jeep Wrangler owner.
JKS has entered the JK Wrangler market with their ACOS Pro system that's available with hydraulic bumpstops, control arms, track bars, coil spring retainers, shock adapters, rear track bar brace, and, of course, Quicker Disconnects sway bar links. The Quicker Disconnects were JKS' first product years ago and have proven to be the best links in a crowded marketplace.
For our JK Wrangler Unlimited suspension system test, we chose to pair our KORE coils and KORE/Fox reservoir shocks with JKS front and rear control arms, track bars, and coil retainers. The JKS control arms are some of the heaviest-duty arms we've ever seen. They utilize factory rubber bushings fore and aft and are adjustable. The JKS arms rotate independently on an internal brass bearing, allowing good suspension flex and axle articulation. The 18 thread-per-inch threads are also internal and ride in grease. They should last a long time and be impervious to outside conditions.
JKS track bars are available with Johnny Joints, polyurethane, or rubber bushings. JKS chose to send us their track bars with OE rubber bushings for quiet performance. Adjustable track bars are a must-have option with any lift.
We also opted for a set of JKS coil spring retainers. This simple product should be included in all suspension systems, but they aren't. JKS should be applauded for coming up with them.
We'll be doing a full write up on the KORE/JKS JK suspension in the print magazine in a summer issue.
