Application Notes:
1. The front engine crossmember must be removed and will not be reinstalled due to drive shaft clearance.
2. Front driveshaft must be removed from front differential to allow for proper droop during installation.
3. It may be necessary that a front CV drive shaft be used in con unction with this lift on either 2 or 4 door
models. 2 Door models may also require a CV rear drive shaft.
4. Used in con unction with the following kits: JL7102 3.5” Fixed Arm Kit, JL7142 3.5” Standard Kit, and
JL7147 3.5” Superflex Kit
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 in ury or death to driver
and passengers. We recommend you always wear your seat belt, drive safely and avoid quick turns and other sud-
den maneuvers. Constant maintenance is required to keep your vehicle safe. Thoroughly inspect your vehicle be-
fore and after every off-road use.
Installation Warning:
All procedures described in these instructions were performed while the vehicle was properly sup-
ported on a vehicle lift. Use caution when supporting the vehicle as removing and installing parts
will change the vehicle center weight. ubicon 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 prod-
ucts without knowledge or experience may eopardize 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 vehi-
cle. Included instructions are guidelines only for recommended procedures and in no way are meant to be defini-
tive. Installer is responsible to insure a safe and controllable vehicle after performing modifications. Do not per-
form test drives on public roads with partially completed installations. Always double and triple check your work
before use.
ESP WA NING NOTE: The 2018 Jeep Wrangler JL 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 ubicon Express strongly suggest that after lift-
ing the vehicle it is returned to the dealer for a computer “flash” to re address tire size and proper
ESP control settings. ubicon Express also recommends that you become familiar with the ESP con-
trols 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.

Front bump stops and coil springs (Photos 1 and 2)
A. Remove stock coil springs.
B. Place the front bump stop (RE1301) in the center of the coil spring and raise the small diameter end of the
Rubicon Express coil into the upper spring bucket and over the lower spring cup and bump stop. Install
front coil shim (RM43013) between the upper isolator and the coil bucket on the passenger side only. Then
raise the axle to seat the upper mount and rotate the coil to properly index in the lower mounts. Be sure to
realign upper isolator tabs with holes in the upper coil bucket.
NOTE: If the axle cannot be dropped far enough from the frame due to brake line or ABS wire
length to install the coil springs remove the bump stop and insert it into the coil. Then slide the coil
over the stock axle mount and re-install the bump stop bolts. (PHOTO # 1)
NOTE: If installing kit with 37” tires on JL Sport edition, use, RE1301, and long bolt.

upper coil bucket
D. Install the replacement rear anti-sway bar end links (RE1151) in place of the previously removed fac-
tory anti-sway bar end links as follows:
1. For vehicles using factory 17” wheels, secure to the sway bar and rear axle using the supplied
1/2” X 2 1/4” button head bolts and hardware. Be sure the bend in sway bar end links is at the
top and facing toward inside of vehicle and the bolt heads are facing in toward frame. (Photo 4)
2. For vehicles using aftermarket wheels with 4.75” of backspacing, secure to the sway bar and rear
axle using the supplied 1/2” X 2 1/4” button head bolts and hardware. Be sure the bend sway
bar end links is at the top and facing toward outside of vehicle and the bolt heads are facing to-

D. Manually disable the factory ESP system before the first test drive. (Refer to owners manual for the disable
procedure) Note the location of steering wheel while driving in a straight line and any driveline vibrations.
E. Ad ust drag link to center the steering wheel. NOTE: Centering the steering wheel is highly critical for proper
ESP function. Minimum factory caster and maximum factory toe-in is the recommended initial setting for align-
ment (see Troubleshooting as well).
F. Ad ust upper control arms if necessary for proper front castor angle and rear pinion angle. NOTE: Shown below
is a diagram of proper pinion angle for a CV style drive shaft (see Troubleshooting as well).
G. Retighten all bolts after 50 miles and again after every off road excursion.
H. After all ad ustments have been made, Rubicon Express recommends that your local Jeep dealership “flash” the
computer to ad ust for proper tire size and ESP control settings.
T OUBLESHOOTING
ear driveline:
Acceleration vibration: Caused by the pinion being too high in relation to the transfer case output shaft. Ad ust up-
per control arm to lower pinion accordingly.
Deceleration vibration: Caused by the pinion being too low in relation to the transfer case output shaft. Ad ust up-
per control arm to raise pinion accordingly.
High speed wobble:
It is a condition where front tires will shimmy after hitting a bump. Avoid bias ply tires and wheels with excessive
offset. Check for worn or loose parts. In most cases a reduction of positive castor will eliminate this condition.
