Extreme-Duty Long Arm Upgrade

Designed for those who already have a short arm suspension system on their vehicle. Our Extreme-Duty Long Arm Upgrade suspension system will provide noticeable improvements in your vehicles' on road handling. The Rubicon Express Extreme-Duty Long Arm System was the first radius long arm suspension available for the Jeep Wrangler JK. This system has been engineered to work WITH your Jeep's Electronic Stability Controls and Rubicon edition electronic sway bar WITHOUT compromising safety. Featuring our world-class chromoly Radius Long Arms, the geometry has been meticulously designed to keep pinion and driveshaft angles in phase, while elimination suspension jacking and unwanted suspension squat. We use 2" x .250 wall Chromoly tubing for our lower control arms for serious off roading use. Our Extreme-Duty Long Arm system coupled with properly valved Rubicon Express shocks allows the JK Wrangler to transmit throttle input to the wheels over varied terrain, providing sure-footed traction and positive suspension feedback. The result is superior on road handling and unrivaled off road performance, without the need to disable factory safety features.
