Nissan 4083 User Manual

INSTALLATION INSTRUCTIONS
98-99 NISSAN FRONTIER 4 WD
KIT # 4083

WARNING

Installation of a Performance Accessories body lift will
change the center of gravity and the handling
characteristics of the vehicle. Because of the higher
center of gravity and larger tires, the vehicle will handle
and react differently both on and off road. You must drive
it 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

Read and understand all instructions, warnings, cautions,
and notes in this sheet and in your owners manual before
you begin the installation of this body lift kit.

CAUTION

Proper installation of a Performance Accessories body lift
kit requires knowledge of the factory recommended
procedures for disassembly an assembly of original
equipment components. It is recommended that the
factory shop manual and any special tools necessary to
your vehicle be on hand during the installation.
Installation of this body lift kit without proper knowledge of
the factory recommended procedures may affect the
performance of these components and the safety of you
vehicle. It is strongly recommended that a certified
mechanic who is familiar with the installation of similar
components install this body lift kit.

WARNING

This body lift kit should only be installed on vehicles that
are in good working condition. Before the installation
begins, the vehicle should be thoroughly inspected for
evidence of corrosion or deformation of the sheet metal
around the factory body mounts. This body lift kit should
not be installed on any vehicle that is suspected to have
been in a collision, or misused. Off road use of your
vehicle with this body lift installed may increase the stress
applied to the factory body mounts. It is not
recommended that any vehicle, with a body lift installed,
be involved in any extreme off road maneuvers such as
jumping. Failure to follow this warning may result in
serious personal injury and/or serious damage to your
vehicle.

WARNING

Performance Accessories strongly discourages the use of
a suspension lift kit or any other lift device in addition to a
body lift kit. A vehicle that uses a combination of lift
devices not originally engineered to be used together may
result in unexpected and unsafe handling characteristics.
Many states now have laws restricting bumper heights
and vehicle lifts. Local laws should be consulted to
determine if the changes you intend to make to your
vehicle complies with state laws.

WARNING

The installation of larger wheel and tire combinations may
reduce the effectiveness of the Anti-lock Braking System.

NOTE

Performance Accessories recommends using the Loctite®
supplied in the kit, on all hardware unless noted in the
instructions.

WARNING

Always wear eye protection when operating power
tools.

If parts are missing from kit, please be prepared to
provide the following information:

1. Name of purchase location

2. Bar Code on side of box

3. Date above bar code

4. Date inside box cover

5. Inspector # from inside box cover

WARNING

Make sure that your vehicle is properly blocked and
secured before you begin installation of this lift kit.

2. Park the vehicle on a clean, dry, flat, level surface.
Block the tires so the vehicle cannot roll in either direction.

WARNING

The Supplemental Restraint System (SRS, air bag) must
be deactivated during installation of the lift kit to avoid
accidental deployment of the air bag while working near
SRS sensors and wiring. Do not allow anyone near the
air bag during installation of the lift kit. Accidental
deployment can result in serious personal injury or death.
Refer to your factory service manual for the
recommended procedure to disable the SRS before
installation of lift blocks. The SRS must be reactivated
before driving the vehicle.

3. Disconnect both battery cables. Be sure to disconnect
the negative cable first, then the positive cable. Remove
the airbag fuse from the fuse box. Consult the vehicle
owner’s manual for the exact location of the fuse.

4. Remove the air cleaner housing from the throttle body.
Remove the bolts that mount the air duct to the upper
radiator mount. Remove the air cleaner and air duct from
the vehicle.

CAUTION

Be sure that the steering shaft does not turn
independently of the steering gearbox. This could cause
the air bag system to malfunction causing possible
personal injury and damage to the vehicle.

5. Mark the steering shaft where it slides into the upper
coupler. Mark the lower coupler and the gearbox where
the steering shaft slides onto the gearbox splined shaft.
This insures proper alignment of the steering after the
steering extension has been installed. Remove the bolt
that mounts the steering shaft to the upper coupler.

2 ’98-’99 Frontier – Kit# 4083

Remove the bolt that mounts the steering shaft to the
gearbox splined shaft. Slide the steering shaft up and off
the gearbox splined shaft, then out of the upper coupler.
Remove the shaft from the vehicle.

WARNING

Use extreme caution when working with the engine
cooling system. Never remove the radiator cap from a hot
radiator. Wait until the engine and radiator has cooled and
the pressure in the system has dissipated. Use care not to
spill any antifreeze/coolant while draining system.
Antifreeze can be harmful to the environment. Take care
to store the drained antifreeze/coolant in a place away
from children and animals. Antifreeze/coolant can be fatal
if swallowed.

6. Drain the radiator into a clean container. Be sure that
the radiator has cooled sufficiently to safely open the
cooling system. Remove the fan shroud from the radiator.
After the radiator has drained completely, loosen the
clamp that mounts the upper radiator hose to the radiator.
Remove the hose from the radiator. Loosen the clamp
that mounts the lower radiator hose to the radiator.
Remove the hose from the radiator. Remove the bolts that
mount the fan shroud to the radiator. Remove the bolts
that mount the top two radiator mounts to the core
support. Remove the mounts from the vehicle. Lay the fan
shroud against the engine. Pull the radiator up and out of
the bottom mount. Remove the radiator from the vehicle.

7. Loosen the two hose clamps that mount both heater
hoses to the heater core at the firewall. Release the
heater hoses from the clamps on the firewall to allow
lifting.

8. Remove the bolt that mounts the a/c hose to the firewall
close to the vacuum brake booster.

9. Unbolt the power steering reservoir and bolt the
extension bracket to the truck using the stock bolts. Bolt
the reservoir to the extension bracket using three 1/4 " x 1"
bolts, six 1/4" washers, and three 1/4" nylock nuts.

10. Remove the guard protecting the brake lines on the
passengers-side front wheel-well. Disconnect the
brackets that mount the steel vacuum lines to the
passenger side frame rail from the frame rail. Check along
the fender well and under the intake manifold to be sure
that there is enough slack in the vacuum lines to allow
lifting. Disconnect the lines as necessary. Make a diagram
to insure proper reconnection after the lifting operation is
complete.

11. Remove two bolts that mount cab safety loop to
floorboard (around driveline through the cross member).

12. Remove the two screws (one on each side) that
mount the outside of the bumper to the fender. These
