INSTALLATION INSTRUCTIONS FOR:
RE7124 2 DOOR JK WRANGLER
RE7144 4 DOOR JK WRANGLER
4.5” SUPER-FLEX SHORT ARM SUSPENSION SYSTEM
Application Notes:
1) The transmission skid plate must be removed and will not be reinstalled due to drive shaft clearance.
2) It is necessary that a front CV drive shaft be used in conjunction with this lift on either 2 or 4 door models. It is also
recommended that a rear CV driveshaft is used on both 2 and 4 door models.
Safety Warning:
Suspension systems or components that enhance the off-road performance of your vehicle may cause it to handle differently, on and off-road, than it did
from the factory. Care must be taken to prevent loss of control or vehicle rollover during sudden maneuvers. Failure to drive the vehicle safely may result
in serious injury or death to driver and passengers. We recommend you always wear your seat belt, drive safely and avoid quick turns and other sudden
maneuvers. Constant maintenance is required to keep your vehicle safe. Thoroughly inspect your vehicle before and after every off-road use.
Installation Warning:
All procedures described in these instructions were performed while the vehicle was properly supported on a vehicle lift. Use caution when
supporting the vehicle as removing and installing parts will change the vehicle center weight. Rubicon Express recommends that chassis support
jacks are always used at the front and rear of the vehicle during the installation of a suspension system.
We recommend that certified technicians perform the installations of our products. Attempts to install these products without knowledge or experience
may jeopardize the safety of the vehicle. These instructions only cover the installation of our products and may not include factory procedures for
disassembly and reassembly of factory components. Read instructions from start to finish and be sure all parts are present before disassembling the
vehicle. Included instructions are guidelines only for recommended procedures and in no way are meant to be definitive. Installer is responsible to insure a
safe and controllable vehicle after performing modifications. Do not perform test drives on public roads with partially completed installations. Always
double and triple check your work before use.
ESP WARNING NOTE: The 2007+ Jeep Wrangler JK is equipped an Electric Stability Program (ESP). This system is designed to help control
the vehicle in times of uncertain traction conditions and roll stability. Due to the complex nature of this program Rubicon Express strongly
suggest that after lifting the vehicle it is returned to the dealer for a computer “flash” to re address tire size and proper ESP control settings.
Rubicon Express also recommends that you become familiar with the ESP controls and how the different level of settings can help you to keep
better control of your vehicle.
WHEEL NOTICE: If using factory wheels it will be necessary to purchase 1.5” wheel spacers to provide proper clearance
to suspension components. Otherwise aftermarket wheels with 4.5” back space measurement will be required.
