Rubicon Express was the first to commercially offer a long arm suspension kit for the Jeep® TJ or LJ. Our Extreme-Duty™ long arm system broke with convention and set the industry standard by which all other kits have been measured. It is designed to be a complete suspension replacement, which utilizes longer control arms to improved lifted suspension geometry. This system will offer you superior stability on and off road, reduced torque roll, and enhancing trail traction over standard short arm lift kits.
