Installation of a Trail Master suspension lift kit will
change the vehicle’s center of gravity and handling characteristics both on- and off-road. You must drive the vehicle safely! Extreme care must be taken to prevent vehicle rollover or loss of control, which could result in serious injury or death. Avoid sudden sharp turns or abrupt
maneuvers and always make sure all vehicle occupants
have their seat belts fastened.
WARNING
Before you install this kit, read and understand all instructions, warnings, cautions, and notes in this instruction sheet and in the vehicle owner’s manual.
CAUTION
Proper installation of this kit requires knowledge of the
factory recommended procedures for removal and installation of original equipment components. We recommend
that the factory shop manual and any special tools
needed to service your vehicle be on hand during the
installation. Installation of this kit without proper knowledge of the factory recommended procedures may affect
the performance of these components and the safety of
the vehicle. We strongly recommend that a certified mechanic familiar with the installation of similar components
install this kit.
WARNING
Many states and municipalities have laws restricting
bumper heights and vehicle lifts. Consult state and local
laws to determine if the changes you intend to make to
the vehicle comply with the law.
WARNING
The installation of larger tires may reduce the effectiveness of the braking system.
WARNING
Always wear eye protection when operating power tools.
WARNING
Before you install this kit, block the vehicle tires to prevent the vehicle from rolling.
WARNING
DO NOT combine suspension, body, or other lift devices.
Use of vehicle with combined lifts may result in unsafe
and/or unexpected handling characteristics.
WARNING
This kit should only be installed on a vehicle that is in
good working condition. Before you install the kit, thoroughly inspect the vehicle for corrosion or deformation of
the sheet metal. If the vehicle is suspected to have been
in a collision or misused, do not install this kit. Off-road
use of your vehicle with this kit installed may increase
the stress applied to the factory components. Failure to
observe this warning may result in serious personal injury and/or severe damage to your vehicle.
NOTE
Lift height may vary depending on vehicle configuration,
engine size, additional accessories, the factory suspension package, and vehicle’s condition.
NOTE
Trail Master recommends using thread locking com-
1
pound on the threads of all kit nuts and bolts unless
specified otherwise in these instructions.

Torque Specifications:
See factory service manual for torque values when
reusing OE fasteners.
Kit parts are prefaced by the word kit and appear in
bold print.
1.Carefully read all warnings and instructions completely before beginning.
2. Verify all parts have been received in this kit by
checking the parts list at the end of this document.
3. Only install this kit on the vehicle for which it is specified. If anytime during the installation you encounter something different from what is outlined in
the instructions, call technical support at (877) 695-
7812.
4. Park vehicle on a clean, dry, flat, level surface and
block tires so vehicle cannot roll in either direction.
5. Measure ride height with the vehicle supporting its
own weight on level ground. To settle the suspension,
the vehicle should be driven forward at least 10 feet
immediately prior to taking these measurements. Ride
height is the measurement from the center of the axle
straight up (vertical) to the fender lip. Record this
measurement for all four wheels.
NOTE
See factory service manual for torque values when re-using
This kit can be installed on 2009-2013 vehicles
equipped with an electric steering rack
Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the
factory service manual. When re-assembling the vehicle it is recommended by the vehicle manufacturer
that certain fasteners are replaced in order to maintain proper retention characteristics. This system
may not include all replacement hardware as recommended by the factory service manual. Additional
replacement hardware should be obtained prior to
installation of this system to meet the requirements
of the factory service manual.
Engine Compartment
1. Disconnect both battery cables. Disconnect nega-tive cable first, then positive cable.
Wheel & Tire Requirements

Troubleshooting
1.Connect both battery cables. Connect positive
cable first, then negative cable.
Miscellaneous
1.Apply kit label (warning) onto dashboard in plain
sight of all vehicle occupants.
2.Adjust headlights.
3.Check all fasteners to ensure they are tight.
4.Ensure all wires, hoses, cables, etc. are properly connected and there is ample slack.
WARNING
If the engine cooling system is hot, the coolant will be
HOT and UNDER PRESSURE. To prevent serious personal injury, wait until the cooling system is completely
cool before removing the cap from the radiator.
5.Start engine and top off cooling system. Purge
air from cooling system according to manufacturer’s instructions. Install radiator cap.
6.Align vehicle
1. Once the vehicle has been lifted, some vehicle
vibration may become more apparent to the
driver. The reason for the vibration may be due to
the angle at which the driveline operates. A suspension lift increases the operating angle of the
driveline and normal vehicle vibration is amplified.
Some vibration characteristics are as follows:
a. Acceleration vibration: vibration felt during
acceleration of the vehicle and caused by the
rear axle pinion angle being too high.
b. Deceleration vibration: vibration felt during
deceleration of the vehicle and caused by the
rear axle pinion angle being too low.
c. General vibration: vibration caused by rear pinion angle in relation to the transfer case output
shaft.
Dynamic Vehicle Check
1. Check steering and suspension in all positions
to ensure that there is no bind and adequate
clearance between all moving, fixed, and
heated members. Check operation of clutch,
brake system, and parking brake. Check operation of transmission and transfer case. Ensure there is full engagement in all gears and
4WD ranges. Check battery connections and
electrical component operations. Test-drive
vehicle.
WARNING
Retorque all fasteners after 500 miles and after off road
use. All suspension lift components should be visually
inspected and fasteners retorqued during routine vehicle
servicing.
WARNING
Re-torque all fasteners after 500 miles and after
off road use. All suspension lift components
should be visually inspected and fasteners retorqued during routine vehicle servicing.
Caution:
Larger wheel and tire combinations increase
stress and wear on steering and suspension
components, which leads to increased maintenance and higher risk for component failure. Larger wheel and tire combinations also alter speedometer calibration, braking effectiveness, center
of gravity, and handling characteristics. Consult
an experienced local off road shop to find what
wheel and tire combinations work best with your
vehicle.
