This JKS J-Flex adjustable rear upper control arm, part number JKS1666, replaces the stock control arm to maintain proper suspension geometry during lift installations. Fits the 2007-2026 Jeep Wrangler, and the 2018 Jeep Wrangler JK. The arm is constructed from 1.5" diameter DOM tubing with a.120" wall thickness and features a forged flex end with 1-1/4"-12 thread jam nut design. At the axle end, OE-style rubber bushings absorb noise and vibration for a quieter, more comfortable ride. The frame-side mount uses a hex-shaped threaded bung for easy angle adjustment, with the flex end allowing up to 15 degrees of misalignment in either direction for excellent articulation. The arm is greaseable to extend bushing life and fully rebuildable.
