Description

JKS Manufacturing adds to its lineup of suspension upgrades for the 2018-2020 Jeep Wrangler JL with new J-Flex rear adjustable upper control arms. These rear J-Flex UCAs join the rest of the J-Flex to allow you to fully upgrade all 8 control arms for a significant improvement to the stock JL control arms both in strength and performance. The arms are constructed from 1.5” OD x .120" DOM tubing and feature robotically welded ends to ensure precision welds and strength. At the axle mounted end OE-durometer premium quality Clevite rubber bushings are preinstalled for great durability, quiet operation and better isolation of road noise and vibrations. At the other end a forged flex joint is threaded in allowing plenty of adjustability for use with with a wide range of lift heights. The forged flex joints use a 1.25”-12 threaded shank along with a jam nut to lock down the length while allowing 30-degrees of misalignment for impressive articulation. Servicing is easy via the grease fitting at the base of the joint.

The adjustable design allows for correctly position the rear axle while correcting pinion angle at a wide range of heights from stock height up to 4.5” of lift and are a direct bolt-in with all Jspec suspension systems for the Jeep JL. These arms come fully assembled right out of the box finished in a gloss black powder coat. Get more out of your Jeep JL with JKS.
