Product details

Built up your Jeep Gladiator JT the right way with these high strength J-Flex rear adjustable lower control arms from JKS. Built for superior strength and smooth operation on/offroad, these arms allow you to correctly position the rear axle for a wide range of stock and lifted ride heights. J-Flex arms are built from heavy duty 2" OD x .250-wall DOM tubing for a massive improvement to factory arms that won't let you down out on the trail. At the axle mount, J-Flex arms feature premium OE style rubber bushings to absorb noise and reduce vibrations for a comfortable, quiet ride and maintenance-free operation. At the frame-side mount, J-Flex arms incorporate a unique hex-shaped threaded bung for easy adjustment of the forged flex end and 1-1/4"-12 threads jam nut Flex end design allows for 30-degrees of misalignment (15 in either direction) for impressive articulation and are greaseable to ensure long bushing life. When the time comes, JKS flex ends are rebuildable. As with all JKS control arms, these J-Flex lower control arms come finished in a durable gloss black powder coat finish and are backed by JKS's limited lifetime warranty. Sold in pairs. Adjustable Rear Upper Control Arms for 2020–2026 Jeep Gladiator JT. Heavy-duty DOM tubing allows precise pinion angle adjustment and improved suspension geometry. 2020-2026 Jeep Gladiator JT Rear Adjustable Upper Control Arm Kit
