INSTALLATION INSTRUCTIONS FOR:
RE6200 XJ 5.5” EXTREME-DUTY SUSPENSION SYSTEM
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 seatbelt,
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:
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.

PRE INSTALLATION NOTE:
Control arm bushings are pre-lubed during initial assembly at Rubicon
Express. As general maintenance the control arm bushings should be
lubed with a silicone base grease as needed. Silicone base grease can
be purchased at your local auto parts store.
The Super-flex joints are also pre-lubed during initial assembly at
Rubicon Express. As general maintenance the super-flex joints should be
greased as needed and the outer spanner nut tightened on the joint.
Any type of grease will work on the Super-flex joints. Spanner nut tools
are available through Rubicon Express (RE3771 & RE3772) if needed for
tightening of the joints.
INSTALLATION:
Note: Read all instructions before beginning installation. 1984-1986
vehicles may require modifications to the front driveshaft for proper
installation. These vehicles use a double offset joint, while later vehicles
use a double cardan (Spicer) style CV-joint. The Spicer CV-joint may be
retro-fitted to the earlier vehicles by changing the transfer case output
yoke for the later model. Lift heights taller than 4.5” will require
modifications to the rear driveshaft. A CV-type driveshaft, transfer case
slip yoke eliminator and axle shims are recommended. Installation time
should be approx. 8 hours.
1. Raise vehicle and support with stands.
2. Remove wheels.
3. Remove front shocks.
4. Remove front sway bar end links.
5. Disconnect front track bar; it may be helpful to disconnect steering
linkage at pitman arm.
6. Remove front spring retainer clamps at bottom spring cup.
7. Remove front springs. Spring compressors may be helpful.
8. Support the front axle with jack stands.
9. Remove factory brake lines and replace with supplied stainless steel
lines. Some require positioning the block and line vertically at the
caliper. Watch line routing, use angle brackets and e-clips.
10. Remove the factory control arms that are to be replaced.
11. See instructions for installation of RE9900 control arm drop
brackets. Install now before proceeding.
12. Install the lower control arms with the rubber bushing at the drop
brackets. The super-flex assembly bolts to axle bracket with
supplied hardware. The offset tube is to be located as low as
possible (zerk on top – SEE PHOTO 1).
13. Install the new upper front adjustable control arms using supplied
hardware at axle end and factory bolt at frame end (don’t fully
tighten until vehicle is back on the ground). Set both control arms
to an initial length of 15 3/8” center to center. Further adjustment
may be needed at time of alignment for caster angle.
14. The 3” bump stop extension is to be located at the axle side spring
cup. Drill a 5/16 hole in center of cup and tap hole with supplied
self-threading bolt. This assembly will not be installed until after
springs are in place. Temporarily attach (use wire or tape) bump
stop inside coil while installing springs. Bolt in place when possible
(after coils are installed).
15. Install springs, use compressor or lever bar using caution, index
spring into lower spring cup. Caution! Coil springs have high
potential energy, which can cause injury.

tower. If your spring rubs the bump stop tower you will need to
