JKS Manufacturing


Since 1989, JKS Manufacturing has developed some of the most widely used and respected products for Jeep vehicles in the off-road industry.

The latest products to hit the market are the new fixed length front and rear J-Link lower control arms available for 2007-2014 Jeep Wrangler JK/JKU. These arms are built to the highest standard from 2'' x .250''-wall DOM tubing, fully welded and finished in a durable black powdercoat. The J-Link arms come ready fully assembled right out of the box with pre-installed Clevite® brand rubber bushings at each end for long lasting bushing performance and superior road noise isolation qualities. Up front these control arms are slightly longer than stock in order to increase and correct caster on vehicles lifted up to 4.5". The arms are formed inward to match the profile of the factory front arms creating plenty of clearance for oversized tires. The rear arms mimic the front arm construction using 2'' x .250-wall DOM tubing and Clevite rubber bushings. The rear arms retain the stock arm length as it allows for proper driveline angles and ensures that the tire stays centered in the wheel well when the suspension is fully compressed.

These new arms are a huge strength upgrade to the factory components. They will work well on their own as an upgrade or can be combined with the popular JKS rotating adjustable upper arms for precise adjustments of front and rear driveline angles and front caster angle.
