| Built on the success of the long-standing performance of the original Rubicon Express long arm system, this package has been modified to take the “limits” out of the Unlimited and provide the ultimate driving experience. Designed as a complete replacement suspension, this features the Rubicon Express rebuildable Super-Flex joints, newly redesigned sway bar disconnect system, and a three piece belly pan with a center section that is easily removed for access to the transfer-case while allowing the control arms to remain attached. This Extreme Duty system improves stock control arm and steering geometry providing better than stock road handling characteristics and off road capabilities that excel beyond compare in every situation. Rubicon Express Extreme Duty packages have always led the market in quality and performance, now the Jeep LJ Unlimited can reap the benefits of that success.
To improve performance even more, we have worked extensively and calculated the right valve codes for proper shock dampening with our Extreme-Duty mono-tube shocks (sold seperately)
The Extreme Duty Long Arm kit delivers:
Increased wheel travel for better traction off road
Minimized axle steer through the suspension cycle
Decreased torque roll, providing a safer, more controllable vehicle
The system is complete with all necessary components including new, heavy duty 4130 steel arms measuring 36" long, a high clearance cross member, and relocated and adjustable front and rear track bars. This kit is 100% bolt on, however, it does require the removal of the factory lower control arm brackets.
Note: Exhaust modifications are required.
Note: The installation of a slip yoke eliminator (SYE) and CV driveshaft on the stock NP231 transfer case is required. The Rubicon NP241 requires a CV yoke instead of an SYE.
