Adjustable Rear Upper Control Arms - TJ/LJ/ZJ Stronger, Adjustable Replacement for Factory Arms These adjustable rear upper control arms are built to replace your Jeep’s factory arms with stronger components...
These adjustable rear upper control arms are built to replace your Jeep’s factory arms with stronger components and added articulation. Designed for 2.5"–4" of suspension lift, they help correct caster and pinion angle for improved driveline alignment. This kit uses larger 1/2" hardware compared to the stock 10mm bolts—about 1/8" larger—so plan to drill out your factory brackets and upgrade your bolts for maximum strength. Fully welded and designed to work with your existing mounts, they’re a direct fit solution for TJ, LJ, and ZJ models.
