Jeep Suspension

XJ Cherokee and MJ Comanche

The Rubicon Express Extreme-Duty Long Arm suspension system is the ultimate 5.5” suspension system for the XJ Cherokee. Designed to be a complete suspension replacement that utilizes longer control arms to improve lifted suspension geometry which makes the vehicle handle better on road and off road while reducing torque roll, and enhancing trail traction over standard short arm lift systems. The Rubicon Express Extreme-Duty long arm suspension system for the XJ features the stout 1/4" thick innovative Rubicon Express three-piece cross member for easy transfer case and transmission access, front Extreme-Duty Radius Long Arm’s with the serviceable Super-Flex spherical ball joints, heavy-duty track bar, heavy-duty track bar bracket brace, and Gen II disconnects. We use 2" x.250 wall Chromoly tubing for our lower control arms for serious off roading use. This suspension will allow the use of 33” tires. Installing a SYE and CV driveshaft is required when using a long arm system.

Applications:

*Shocks listed are recommended mono-tubes and are sold separately unless otherwise specificed
