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 maneu-
vers. 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 installa-
tion 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 sup-
ported on a two post vehicle lift with safety jacks.
Use caution during all disassembly and assembly steps to insure suspension components are not over extend-
ed 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 disas-
sembly 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.

IMPORTANT NOTE:
This suspension system was developed using a 38” x 12.5” tire with 20” x 9” wheel
and a offset of +25mm. 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 11.5” 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 dif-
ferentials may occur.
A lifted vehicle may have different headlight aim performance. ReadyLIFT recom-
mends marking and recording the headlight beam position before kit installation and
then adjusting, if necessary, the headlamps to the same height settings after kit in-
stallation. 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 distanc-
es.) 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 oth-
er. 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 head-
lights.
IMPORTANT NOTE:
This kit was designed using the standard frame option vehicle. Vehicles that have
been equipped with snow prep / ambulance packages will not see the same lift height
gained as they come 1” to 1.5” taller from the factory due to heavier rated front
springs. The lift height achieved is 6” to 8” over the standard frame option vehicles
depending on the kit purchased. The springs provided in this kit are not designed to
carry snow plow package and may see decreased front end heights if done.
Due to differences in factory spring length between model years, vehicles made be-
fore model year 2020, with standard duty springs, may only exhibit a 6.5” increase in
ride height.
The lift blocks in this kit are not designed to work with aftermarket or factory add on
air spring/load leveling kits that attach to the bump stop tangs. Use of this type of air
bag system will void all block warranties and can cause failure of the block bump stop
tang.

Pre Installation Measurements
It is imperative that you record the following measurements and factory components.
ReadyLIFT test and records as much data from each application as possible. Vehicle
manufactures may change components or add models with different options. By re-
cording and not exceeding the fender to hub center that ReadyLIFT call out will en-
sure the lift on your vehicle is correct. This measurements and components will effect
the completion of this lift kit. Failure to do so may result in over lifting, causing prem-
ature failure of axles, CV boots and drivetrain. Over lifting a vehicle will also result in
a incorrect wheel alignment. This will wear tires incorrectly inside or outside edge. An
Incorrect alignment will cause poor vehicle handling issue such as under steer. Over
lifting will also cause a shock top off condition, creating poor ride quality and pops
and clunks 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 adjusting to factory
position after the completion will ensure a safe and enjoyable experience.
