Advanced driver-assistance systems (ADAS) are electronic systems in a vehicle that use advanced technologies to assist the driver. Installation of a
Rancho lift kit in any vehicle that features this technology may impact or change the ADAS system, and requires immediate re-calibration by the dealer.
This product warranty is voided if the vehicle’s ADAS systems are not re
-calibrated by a qualified technician after kit installation
Carefully read, understand, and follow the instructions provided in this manual, and keep it in a safe place for future reference. If you have any doubt
whatsoever regarding the installation or maintenance of your Rancho suspension system, please see your retailer for assistance or advice. Failure to
follow the warnings and instructions provided herein can result in the failure of the suspension system or can cause you to lose control of your vehicle,
resulting in an accident, severe personal injury or death.
These instructions should remain in the vehicle glove box for future reference
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. Some
components required for the installation of this kit may need to
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 at end
of instruction.
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 1-800-325-8886.
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 at end of
instruction. USE
A TORQUE
WRENCH
for
accurate
measurements.
I. Some of the service procedures require the use of special
tools designed for specific procedures. If you do not know how
to safely use any of these tools, or do not have them, stop the
project and consult a qualified mechanic. See tool list
J. It is extremely important to replace coil springs, axle flanges,
and drive shaft/pinion relationships as original. Be sure to mark
left/right, front/rear, and indexing of mating parts before
disassembly. A paint marker or light colored nail polish is handy
for this.
K. Suspension components that use rubber or urethane bushings
should be tightened with the vehicle at normal ride height unless
otherwise specified. This will prevent premature failure of the
bushing and maintain ride comfort.
L. The required installation time for this system is approximately
2 to 3 hours for two people. Check off the number at the
beginning of each step when you finish it. Then when you stop
during the installation, it will be easier to find where you need to
continue.
N. Important information for the end user is contained in the
consumer/installer information pack. If you are installing this
system for someone else, place the information pack on the
driver’s seat. Please include the installation instructions when
you finish.
O.
The lifespan of Rancho products depends on many
factors. Improper use, abuse or harsh use in general may
compromise the integrity of the suspension system and
significantly reduce its lifespan. The suspension system is also
subject to wear over time. Have the suspension system regularly
inspected and maintained by qualified mechanics. If the
inspection reveals any damage or excessive wear, no matter how
slight, immediately replace or repair the component. The
suspension system must be regularly maintained in order to
optimize its safe and efficient use. The more severe the
conditions under which the suspension system is operated, the
more often it must be inspected and maintained.
