Enhance the ride quality and driving comfort of your Jeep Wrangler JL or Gladiator JT with JKS J-FLEX front upper adjustable control arms. They make it easy to dial in correct geometry and also provide added rigidity. Constructed of high strength DOM tubing, J-Flex arms feature robotically welded ends form maximum strength. At the frame side, a forged end is threaded in to allow ample adjustability to suit a wide range of ride heights from stock to 6" of lift. The forged ends allow 15 degrees of articulation in either direction and grease fittings allow for easy servicing. J-Flex arms come fully assembled right out of the box finished in a gloss black powder coat. Sold in pairs.
