WARNING
Installation of a Trail Master suspension lift kit will change the
vehicle’s center of gravity and handling characteristics both onand 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 shar p 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 la ws 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 une xpected
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
1
threads of all kit nuts and bolts unless specified otherwise in thes e
instructions.

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.
NOTE
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
negative cable first, then positive cable.
Wheel & Tire Requirements
The factory wheel and tire combination will fit
once this kit is installed.
Tire & Wheel Information:
Due to differences in manufacturing, dimensions and
inflated measurements, tire and wheel combinations
should be test fit prior to installation. Tire and wheel
choice is crucial in assuring proper fit, performance,
and the safety of your Trailmaster equipped vehicle.
For this application, we recommend a wheel not to
exceed 10” in width with a maximum backspacing of
5 3/4” must be used. Additionally, a quality tire of
radial design, not exceeding 37” tall X 12.50” wide is
also recommended. Violation of these recommendations will not be endorsed as acceptable by Trailmaster Suspension and will void any and all warranties
either written or implied.

15. Remove the (2) bolts that secure the center
drive shaft bearing. Lower bearing and install
1/4” of shim thickness for each inch of rear
lift. Use new 7/16” X 2 1/4” bolts and torque
to 55 ft./lbs.
NOTE: 1/4” of shim for each inch of
lift is only a starting point. Only by driving the
vehicle and adding or removing shims can the
high speed vibration be totally eliminated. The
off the line vibration is caused by axle wrap up
and cannot be eliminated with these products.
16. If vehicle came equipped with a rear sway
bar, assemble the rear sway bar end links
(82-2446) using the bushings (45359) and
sleeves (60859H).
17. Secure the new rear sway bar end links (82-
2446) to the frame and the sway bar using the
provided 12mm-1.75 X 70mm. Torque the
bolts according to the torque chart on page
19.
18. Secure the new rear brake line bracket (90-
7031) to the rear axle by reinstalling the vent
tube.
19. Secure the OE brake line bracket to the new
brake line bracket (90-7031) using the supplied 3/8” X 1” bolt and hardware.
20. Reinstall the wheels and tires and lower the
vehicle to the ground. Torque lug nuts to
manufacturer specification.

21. Torque the spring mounts at this time. The
front bolts are torqued to 250 ft. lbs. and the
rear bolts are torqued to 185 ft. lbs. Torque
the 5/8” U-bolts to 120 ft. lbs.
22. Re-check the wheel lug torque on all four
wheels at this time.
23. Re-check all
hardware (both the front and the
rear) for proper installation and torque!!
24. If you wish, you may trim the excess u-bolt
thread length. If you do this you should
leave approximately one inch of thread exposed after the U-bolts are torqued.
25. On both sides of the vehicle, check the
routing of the brake lines and the ABS wire
harnesses. There must be no pinching,
rubbing, or stretching of either component.
Reposition them if needed.
NOTES:
On completion of the installation, have the
suspension and headlights re-aligned.
After 100 miles recheck for proper torque
on all newly installed hardware.
Recheck all hardware for tightness after
off road use.

NOTES:
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
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.
On completion of the installation, have the
suspension and headlights re-aligned.
After 100 miles recheck for proper torque
on all newly installed hardware.
Recheck all hardware for tightness after
off road use.
IMPORTANT!: 18” OR LARGER WHEELS
MUST BE USED IN
CONJUNCTION WITH THIS LIFT KIT!

Notice to Owner Operator, Dealer and Installer:
Vehicles that have been enhanced for off-road performance often have unique handling characteristics
due to the higher center of gravity and larger tires. This vehicle may handle, react and stop differently than
many passenger cars or unmodified vehicles, both on and off–road. You must drive your vehicle safely!
Extreme care should always be taken to prevent vehicle rollover or loss of control, which can result in serious injury or even death. Always avoid sudden sharp turns or abrupt maneuvers and allow more time and
distance for braking! Trail Master Suspension
reminds you to fasten your seat belts at all times and reduce speed! We will gladly answer any questions concerning the design, function, maintenance and correct use of our products.
Please make sure your Dealer/Installer explains and delivers all warning notices, warranty forms
and instruction sheets included with Trail Master Suspension
product.
Application listings in this catalog have been carefully fit checked for each model and year denoted. However, Trail Master Suspension
reserves the right to update as necessary, without notice, and will not be
held responsible for misprints, changes or variations made by vehicle manufacturers. Please call when in
question regarding new model year, vehicles not listed by specific body or chassis styles or vehicles not
originally distributed in the USA.
Please note that certain mechanical aspects of any suspension lift product may accelerate ordinary wear of original equipment components. Further, installation of certain Trail Master Suspension
products may void the vehicle’s factory warranty as it pertains to certain covered parts; it is the consumer’s responsibility to check with their local dealer for warranty coverage before installation of the lift.
