Rubicon Express was the first to comercially offer a long arm suspension system for the Jeep TJ; this same industry leading design is available for the Wrangler Unlimited LJ.Our LJ Extreme-Duty Long Arm System is designed to be a complete suspension replacement, which utilizes longer control arms to improve lifted suspension geometry. This system will offer you superior stability on and off road, reduced torque roll, and enhanced trail traction over standard short arm lift systems. The Rubicon Extreme-Duty Long Arm suspension system includes a three-piece belly pan for easy transfer case and transmission access. Our LJ Extreme-Duty Long Arm suspension System is the best performing and most technologically advanced system of its kind; there is no better long arm suspension system available for your LJ. The first and still the best. Rubicon's Long Arm Tri-Link system eliminates the rear track bar, allowing for true up/down wheel travel, while enhancing anti-squat for those steep climbs. On-road tracking is improved, and the kit is bolt-on for factory Dana 35 and Dana 44 rear ends. Kit includes front and rear control arms using 2 .250 wall, 4130 chromoly material. Also included with the kit is Rubicon's newest misalignment joint design, the Builder Ball. This setup eliminates the rear track bar and has up to 32 degrees of misalignment in a giant-sized 3" OD housing.

Important Notes:

  • Maximum tire size: 33"
  • Drilling is required.
  • Vehicle will require alignment after kit is installed.
  • TJ must use with SYE kit and C/V drive shaft. LJ may use RE2100 Transfer Case drop.
