READ INSTRUCTIONS THOROUGHLY AND COMPLETELY BEFORE BEGINNING INSTALLATION.
INSTALLATION BY A CERTIFIED PROFESSIONAL MECHANIC IS HIGHLY RECOMMENDED.
READYLIFT® IS NOT RESPONSIBLE FOR ANY DAMAGE OR FAILURE RESULTING FROM
IMPROPER INSTALLATION. Safety Warning
MISUSE OF THIS PRODUCT COULD LEAD TO INJURY OR DEATH. Suspension systems or
components that enhance the on and off-road performance of your vehicle may
cause it to handle differently than it did from the factory. Extreme care must
be used to prevent loss of control or vehicle rollover during abrupt
maneuvers. Always operate your vehicle at reduced speeds to ensure your
ability to control your vehicle under all driving conditions. Failure to drive
safely may result in serious injury or death to driver and passengers. Driver
and passengers must ALWAYS wear your seat belts, avoid quick sharp turns and
other sudden maneuvers. ReadyLIFT Suspension does not recommend the combined
use of suspension lifts, body lifts, or other lifting devices. You should
never operate your vehicle under the influence of alcohol or drugs. Constant
maintenance is required to keep your vehicle safe. Thoroughly inspect your
vehicle before and after every off-road use.
It is the responsibility of the retailer and/or the installer to review all
state and local laws, with the end user of this product, related to bumper
height laws and the lifting of their vehicle before the purchase and
installation of any ReadyLIFT products.
It is the responsibility of the driver/s to check their surrounding area for
obstructions, people, and animals before moving the vehicle. All raised
vehicles have increased blind spots; damage, injury and/or death can occur if
these instructions are not followed.
.
Installation Warning All steps and procedures described in these instructions
were performed while the vehicle was properly supported on a two post vehicle
lift with safety jacks. Use caution during all disassembly and assembly steps
to insure suspension components are not over extended causing damage to any
vehicle components and parts included in this kit. Included instructions are
guidelines only for recommended procedures and are not meant to be definitive.
Installer is responsible to insure a safe and controllable vehicle after
performing modifications. ReadyLIFT Suspension recommends the use of an OE
Service Manual for model/year of vehicle when disassembly and assembly of
factory and related components. Unless otherwise specified, tighten all bolts
and fasteners to standard torque specifications listed within the OE Service
Manual. Suspension components that use rubber or urethane bushings should be
tightened with the vehicle at normal ride height. This will prevent premature
wear or failure of the bushing and maintain ride comfort. Larger tire and
wheel combinations may increase leverage on suspension, steering, and related
components. Due to payload options and initial ride height variances, the
amount of lift is a base figure. Final ride height dimensions may vary in
accordance to original vehicle ride height. Always measure the vehicle ride
height prior to beginning installation.
SAEJ2492 Warning
By installing this product, you acknowledge that the suspension of this
vehicle has been modified. As a result, this vehicle may handle differently
than that of factory-equipped vehicles. As with any vehicle, extreme care must
be used to prevent loss of control or roll-over during sharp turns or abrupt
maneuvers. Always wear seat belts, and drive safely, recognizing that reduced
speeds and specialized driving techniques may be required. Failure to drive
this vehicle safely may result in serious injury or death. Do not drive this
vehicle unless you are familiar with its unique handling characteristics and
are confident of your ability to maintain control under all driving
conditions. Some modifications (and combinations of modifications) are not
recommended and may not be permitted in your state. Consult your owner’s
manual, the instructions accompanying this product, and state laws before
undertaking these modifications. You are responsible for the legality and
safety of the vehicle you modify using these components.

Due to payload options and initial ride height variances, the amount of lift
is a base figure. Final ride height dimensions may vary in accordance to
original vehicle ride height. Always measure the vehicle ride height prior to
beginning installation. A lifted vehicle may have different headlight aim
performance. ReadyLIFT recommends marking and recording the headlight beam
position before kit installation and then adjusting, if necessary, the
headlamps to the same height settings after kit installation. Set the vehicle
on a level surface 10′ to 15′ from a solid wall or garage door. (This is a
general distance with some manufacturers requiring different distances.) Note
the top height of the low beam’s bright spot, the top of the most intense part
of the beam, for driver and passenger side. Height may vary from side to side.
Repeat this procedure and adjust after lift kit is installed. Adjust if the
aim is off by turning the adjusters gradually (a quarter of a turn) and
looking to see where the new alignment falls. It may be easier to block one
headlamp while adjusting the other. Consult the owner operation manual for
procedures to adjust headlights – many automakers offer headlight aiming
specs. Some states have their own specifications when it comes to headlight
aim, so it’s best to follow those rules when alighting headlights.
This suspension system was developed using a 37 x 12.5 tire with 20×9 wheel
and a offset of 18mm. If wider tires are used, offset wheels may be necessary
and trimming may be required. Factory wheels can be used but are not
recommended with tires over 10.5″ wide. The stock spare rim can be run in an
emergency – exercise extreme caution under stock spare tire operating
conditions. Please note that, if running the spare factory tire, it is done
for short distances and a speed not to exceed 45mph or damage to differentials
may occur.
IMPORTANT NOTE:
Kit not compatible with aftermarket lift struts or other lift systems. Use of
additional lift components will damage vehicle. Kit is not compatible with
factory rear coil spring suspension or advanced vehicle suspensions which may
include electronic shocks TRD Pro configurations.

PRE-INSTALLATION MEASUREMENTS:
It is imperative that you record the following measurements and factory components in the tables below. ReadyLIFT tests and records as much data from each application as available at the time of product development. Vehicle manufacturers may change components or add models with different options. Recording and not exceeding the fender-to-hub-center ReadyLIFT calls out will ensure the lift on the vehicle is correct. These measurements will affect the performance of this lift kit. Failure to ensure proper stock conditions may result in over lifting, causing premature failure of axles, CV boots and drivetrain. Over lifting a vehicle will also result in an incorrect wheel alignment. This will wear tires incorrectly. Incorrect alignment will cause poor vehicle handling issues including but not limited to under steer. Over lifting will also cause a shock top off condition resulting in poor ride quality accompanied by pops and clunks which are symptoms of prematurely wearing components. Failure to adjust head lamps may cause dangerous driving conditions for you and other drivers on the road. Record the head lamp position before the installation of this lift or leveling kit and adjust to original factory position after the completion to ensure a safe and enjoyable experience.

DAMAGE AND/OR PERSONAL INJURY OR DEATH TO THE DRIVER AND/OR OTHERS.
Final Checks & Adjustments Once the vehicle is lowered to the ground, check
all parts which have rubber or urethane components to ensure proper torque.
Torque lug nuts to the wheel manufacturer specs. Move vehicle backwards and
forwards a short distance to allow suspension components to adjust. Turn the
front wheels completely left then right and verify adequate tire, wheel, brake
line, and ABS wire clearance. Test and inspect steering, brake and suspension
components for tightness and proper operation. Inspect brakes hoses and ABS
lines for adequate slack at full extension, adjust as necessary. RECHECK ALL
HARDWARE FOR PROPER TORQUE VALUES AFTER 500 MILES, AND THEN PERIODICALLY AT
EACH SERVICE INTERVAL THERAFTER.
Vehicle Handling Warning Increasing the height of your vehicle raises the
center of gravity and can affect stability and control. Use caution on turns
and when making steering corrections. Vehicles with larger tires and wheels
will handle differently than stock vehicles. Take time to familiarize yourself
with the handling of your vehicle.
Wheel Alignment/Headlamp Adjustment It is necessary to have a proper and
professional wheel alignment performed by a certified alignment technician.
Align the vehicle to factory specifications. It is recommended that your
vehicle alignment be checked after any off-road driving. In addition to your
vehicle alignment, for your safety and others, it is necessary to check and
adjust your vehicle headlamps for proper aim and alignment. If the vehicle is
equipped with active or passive safety/collision monitoring and/or avoidance
systems including, but not limited to, camera- or radar-based systems, check
and adjust your vehicle’s systems for proper aim and function.
