Long Arm Upgrade Kit 4"-6" lift 2004-06 Wrangler LJ Unlimited

Push your Wrangler TJ to the next level of off-road performance with the Rough Country 63800U Long Arm Upgrade. Built for serious trail abuse, this long arm upgrade transforms your Jeep’s suspension geometry for improved articulation, smoother ride quality, and better control over brutal terrain. Designed to handle steep climbs, deep flex, and punishing obstacles, the heavy-duty long arm setup helps reduce suspension bind while maximizing wheel travel where it matters most. Whether you’re crawling over rocks or hammering through rough backcountry trails, the 63800U delivers the strength, stability, and trail-dominating performance hardcore Jeep owners demand. Give your TJ the suspension upgrade that’s ready to take on bigger tires, tougher trails, and the kind of adventures that leave pavement far behind.
