INSTALLATION INSTRUCTIONS FOR: 

RE7330 2 & 4 DOOR JK WRANGLER  

LONG ARM UPGRADE KIT

 

Congratulations on purchasing the ultimate suspension package available for the Jeep JK. 

 

Application Notes:  

1)

 

The JK long arm upgrade kit is not a complete kit, additional parts such as but not limited to coil springs, track bars, track bar 

brackets, and steering components will also be needed for a complete installation. This kit is designed to replace the stock short 
arm configuration. Installation of the system will require the rear lower rear control arm brackets are removed from the frame 
along with modification or removal of the upper rear arm brackets. The front lower control arm brackets can remain on the frame 
but we suggest that they are removed for a better visual appearance.   

2)

 

This kit does require the removal of the fuel tank for installation. Special tools are not required to remove the fuel tank. 

3)

 

This kit does not require modifications to the exhaust system, however it is recommended that the exhaust, from the transmission 
cross member back is removed prior to and replaced after installation to better access the frame rail during rear bracket 
installation.  

4)

 

The transmission skid plate must be removed and will not be reinstalled due to drive shaft clearance.  

5)

 

It is absolutely necessary that a front and rear CV drive shaft be used in conjunction with this lift.  

 

 
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.
