12) Never install the suspension system if you are under the
effects of alcohol, medications and/or drugs. If you are taking
prescription or over the counter medication, you must consult a
medical professional regarding any side effects of the
medication that could hinder your ability to work safely.
III. WARNINGS AND INSTRUCTIONS AFTER
INSTALLATION
13) After installation is complete, drive the vehicle slowly in
an area free from heavy traffic for at least three (3) miles.
Likewise, before traveling on any highways or at a high rate of
speed, drive the vehicle for ten (ten) miles on side roads at
moderate speed. If you hear any strange noise or feel unusual
vibration, if a component of the suspension system is not
operating properly, or if any warning lights illuminate or
buzzers sound, stop the vehicle immediately. Identify the
cause and take any necessary remedial action.
14) Confirm that all components of the vehicle, including all
lights (headlights, turn signals, brake lights, etc.), linkages
(accelerator, etc.), electrical switches and controls (windshield
wipers and defoggers, etc.), and other warning devices (low
tire pressure monitoring systems) are fully operational.
15) Your headlights will need to be readjusted before the
vehicle is used on the roads. Consult the vehicle owners’
manual.
16) The speedometer and odometer will need to be
recalibrated after installation. See your dealer.
17) Confirm proper rear view and side view while seated in
the driver seat. Install supplemental mirrors as necessary.
18) Your original low tire pressure monitoring system may be
re-installed in your new wheels. However, if you choose to
purchase a new system, see your dealer to have them properly
calibrated. Proper tire pressure is critical to safe operation of
the vehicle.
IV. OPERATION
19) Because it has been modified, the vehicle will not handle,
turn, accelerate or stop in the same manner as an unmodified
vehicle. In addition, the crash protection systems designed in
the vehicle may operate differently from an unmodified vehicle.
For example, turning and evasive maneuvers must be
executed at a slower rate of speed. Further, there is a greater
risk that the vehicle could roll over. These differences could
result in an increased possibility of an accident, personal injury
or death. Learn the vehicle’s operations and handling
characterizes and drive accordantly.
V. IMPORTANT NOTES
A. Before installing this system, have the vehicle’s
alignment and frame checked by a certified technician. The
alignment must be within factory specifications and the frame
of the vehicle must be sound (no cracks, damage or
corrosion).
B. The components of Rancho’s suspension system are
designed as a single integrated system. To avoid
compromises in terms of safety, performance, durability or
function, do not substitute Rancho components with
components manufactured by other companies. Use of other
components will result in the forfeiture of any type of warranty
on the vehicle/suspension system. New Rancho shock
absorbers are required and must be purchased separately.

C. Do not powder-coat or plate any of the components in
this system. To change the appearance of components,
automotive paint can be applied over the original coating.
D. Each hardware kit in this system contains fasteners of
high strength and specific size. Do not mix hardware kits or
substitute a fastener of lesser strength. See bolt identification
table on page 2.
E. Compare the contents of this system with the parts
list in these instructions. If any parts are missing, contact the
Rancho Technical Department at 1-734-384-7804.
F. Install all nuts and bolts with a flat washer. When both
SAE (small OD) and USS (large OD) washers are used in a
fastener assembly, place the USS washer against the slotted
hole and the SAE washer against the round hole.
G. Apply a drop of thread locking compound to all bolts
during installation. CAUTION: Thread locking compound
may irritate sensitive skin. Read warning label on container
before use.
H. Unless otherwise specified, tighten all nuts and bolts
to the standard torque specifications shown in the table on
page 4. USE A TORQUE WRENCH for accurate
measurements.
I. Some of the service procedures require the use of
special tools designed for specific procedures. The following
tools and supplies are recommended for proper installation of
this system: If you do not know how to safely use any of these
tools, stop the project and consult a qualified mechanic.
