WARNING

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

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.

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.

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 com­pound on the threads of all kit nuts and bolts unless
specified otherwise in these instructions.

Before Starting Installation

NOTE

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.
