 WARNING: 

READ  ALL  INSTRUCTIONS  THOROUGHLY  FROM 

START  TO  FINISH  BEFORE  BEGINNING  INSTALLATION.  Failure  to 
follow the warnings and instructions provided herein can result in an 
accident, severe personal injury or death. 

PRELIMINARY 

This  manual  presumes  that  all  persons  installing  this  suspension 
system have a high level of mechanical training and experience, and 
have available to them all necessary tools and safety equipment. This 
manual is not and should not be construed as an exhaustive list of all 
required  safety  measures.  Personnel  should  rely  primarily  on  their 
training and experience, as well as on their own common sense. 
This  Manual  is  to  be  read  as  a  supplement  to,  and  must  not  be 
construed  as  a  substitute  for,  the  owner’s  manual  and/or  shop 
manual  that  originally  accompanied  the  vehicle.  Refer  to  such  use, 
operation,  maintenance  and  safety  manuals  as  necessary,  and 
especially  after  installation  is  complete,  to  insure  proper  vehicle 
operation. 
The following terminology has been used in this Manual: 
ACCIDENT:  Any event which could cause personal injury or death to 

anyone installing or using the suspension system, as well 
as to passengers and bystanders, or otherwise may result 
in property damage. 

PRE-INSTALLATION WARNINGS and INSTRUCTIONS 

 WARNING: Only the following rim/tire sizes may be used with this 

suspension system: 295/60R20 tire, 20x9-in 0 offset wheel. 

Use of any other rim/tire combination increases the risk of a roll-over 
and/or accident, resulting in severe personal injury or death.  

  WARNING:  This  suspension  system  will  enhance  the  off-road 

performance of your vehicle. It will handle differently; both on and off-
road, from a factory equipped passenger car or truck. Failure to drive 
this vehicle safely may result in serious injury or death to the driver and 
passengers. ALWAYS WEAR your seat belts, REDUCE your speed, and 
AVOID sharp turns and other abrupt maneuvers 

1)

 

Service  and  repair  tasks  require  specialized  knowledge,  training, 

tools,  and  experience.  General  mechanical  aptitude  may  not  be 
sufficient to properly install this suspension system. If you have any 
doubt  whatsoever  regarding  your  ability  to  properly  install  the 
suspension system, please consult a qualified mechanic.  

2)

 

Your  brake  lines  and fuel  lines  should remain  undisturbed  during 

and  after  installation.  If  you  think  you  need  to  modify  these 
components in any way, you are mistaken. You are installing the lift 
improperly and will be creating a significant risk of an accident. In case 
of any doubt, consult a qualified mechanic. 

3)

 

If  any  component  does  not  fit  properly, something  is  wrong.  You 

are installing the lift kit improperly and will be creating a significant 
risk  of  an  accident.  Never  modify  any  component  of  the  vehicle  or 
suspension system, except as instructed herein. Do not continue with 
installation until you have identified the problem. 

4)

 

Several of the procedures described herein require at least two (2) 

persons to safely complete the task. If you have any doubt about your 
ability  to  complete  any  operation  by  yourself,  always  ask  for  help 
from a qualified assistant. 

5)

 

Before  starting  any  operation,  confirm  that  all  personal  safety 

devices and safety equipment are in proper condition and position. 

6)

 

Give your work undivided attention. Looking around, carrying on a 

conversation and "horse-play" are careless acts that can result in an 
error in installation and/or serious injury. 

7)

 

Install  only  tires  approved  by  the  United  States  Department  of 

Transportation (“DOT approved”). Make sure the rim and tire size are 
properly matched. 

8)

 

If  any  components  of  the  vehicle  or  suspension  system  are 

damaged  in  any  way  during  installation,  immediately  replace  the 
component.  

9)

 

During  installation,  carefully  inspect  all  parts  of  the  vehicle  and 

replace anything that is worn or damaged. 

10)

 

Nip  points  present  the  risk  of  the  catching,  lacerating,  crushing 

and/or amputating fingers, hands, limbs and other body parts during 
operations. Always keep clear. Wear protective gloves. 

11)

 

Oil  and  hydraulic  fluids  are  poisonous,  dangerous  to  health  and 

are known to the State of California to cause cancer, birth defects or 
other  reproductive  harm.  Do  not  inhale  vapors  or  swallow.  Do  not 
allow  contact  with  the  eyes  or  skin.  Should  any  oil  or  fluids  be 
swallowed  or  inhaled  or  come  into  contact  with  the  eyes, 
immediately follow the safety precautions on the label or call a poison 
control  center  immediately.  Should  any  of  the  oil  or  fluids  contact 
your skin, immediately wash thoroughly. 

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. 

AFTER INSTALLATION WARNINGS AND INSTRUCTIONS  

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 (10) 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. 

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.
