Countless accessories are on the market that
can help you personalize your truck. Often these
accessories are more than cosmetic: Some are designed to protect and preserve the car; others offer
increased performance and improved fuel efficiency. Your choice of custom parts depends on what
you want out of your truck, but keep in mind that
some car manufacturers void their warranties if the
vehicle is altered. This booklet is designed to get
you started by offering ideas.
TRUCK BED LINER
A liner protects the truck bed against dents,
scratches, and rust. Because it helps keep the
truck bed looking new, It improves the resale
value. Installation methods vary from manufacturer
to manufacturer, but following are some typical installation instructions. Keep in mind that failure to
install the liner according to the manufacturer's instructions can result in damage to person or
property and can also void the warranty.
1. Position the liner in the truck bed.
2. Align the drill with the center of each of the
truck stake holes, then drill a 1/2"-diameter hole
through the liner at each of these locations.
3. Place a washer over each roundhead screw
and insert the screws through the liner rails.
4. Start the toggle wing nuts on the screws,
push the screws down into the stake pocket holes,
and tighten lightly.
5. Center the tailgate cover over the tailgate.
6. Drill two 9/64"-diameter holes at the top of
the tailgate cover, one on the right and one on the
left Drill completely through the tailgate cover and
the tailgate.
7. Drill four 9/64"-diameter holes along the bottom of the tailgate, again making sure to drill
through both the cover and tailgate.
NOTE: Be sure to prime the edges of all drilled
holes with an epoxy or zinc-based primer.
8. Drill six 3/8"-diameter holes through the tailgate cover only, using the previously drilled
9/64"diameter holes as pilot holes.
9. Slip one washer and two spacers over two
screws and fasten the top of the tailgate with these
screws. Install the washers with the flange up.
10. Slip one washer and one spacer over four
screws and fasten the bottom of the tailgate cover
with these screws. Again, Install the washers with
the flange up.
11. Snap a plastic cover over each screw.
WARNING: Be careful in rainy weather most
truck bed liners become slippery when wet.
TONNEAU COVER
Besides enhancing the appearance of the truck,
tonneau covers also offer practical advantages.
They protect cargo from the wind and weather and
make the truck more aerodynamically sound,
which saves fuel. General installation instructions
follow, but be sure to read the manufacturer's instructions carefully.
NOTE: Warm the cover to room temperature before beginning the installation process.
1. Locate and mark the center of the truck bed
behind the rear window.
2. Using a 1/8" bit, drill a hole 3/4" from the
front edge of the bed rail in the center of the truck
bed.
3. Install a stud in the hole.
4. Attach the center snap in the cover to the
stud in the truck bed.
5. Standing on the driver's side, pull the corner
of the cover as tight as possible down the front
edge of the bed.
6. Mark the position of the corner snap and drill
a hole 3/4" from the front of the bed for the corner
stud. Install the stud.
7. Repeat steps 5 and 6 on the passengers side.
8. Locate and mark the center of the tailgate.
9. Pulling the cover from front to back as tight
as possible and keeping the center snap of the
cover in the center of the tailgate, mark the position of the center snap.
10. Drill the hole, install the stud, and snap the
cover to the stud.
11. Pulling the rear corner over the side and toward the rear of the truck, mark the position of the
corner snap.
12. Drill the hole, install the stud, and snap the
cover to the stud.
13. Repeat the process for the other rear corner.
14. Making sure they align with the studs previously installed, install the remaining studs and
snap the cover to them.
GROUND EFFECTS
Like the tonneau cover, ground effects have
both aesthetic and practical value. In fact, many
people are surprised when they realize the extent
of the aerodynamic benefits that result from installing an air dam, rear valance, and side skirts. Once
again, the installation instructions that follow are
general in nature; read and follow those provided
with the ground effects you purchase. Also, to prevent chips and nicks, do all fitting up of parts
before any paint is applied.
Air Dam installation
1. If applicable, remove the factory air dam from
under the front bumper. Then remove the bumper
fasteners, including any support brackets, and the
turn signal lights.
2. Place the right air dam up and under the bottom of the bumper lip with its side flat against the
truck side.
3. When satisfied with the placement of the air
dam, mark the location of the mounting holes.
4. Remove the air dam and drill out the marked
holes 1/4" in diameter.
5. Attach the air dam to the truck using the
screws and lock washers provided.
6. Repeat steps 1 through 5 to install the left air
dam.
7. Insert the two center air dam pieces between
the left and right air dams. Adjust them so that the
joints of all the air dams line up.
8. Mark the location of the mounting holes, remove the center air dam pieces, and drill out the
marked holes 1/4" deep.

reinstall the bumper fasteners and turn signal
lights.
Rear Valance Installation
1. Remove the license plate light and bracket
from the rear of the truck.
2. Mark and drill holes in the center of the valance that correspond to the holes in the light
bracket.
3. Use nuts and bolts to secure the light to the
valance.
4. Drill a 5/16°-diameter hole in the rear rocker
panel, approximately 27" from the side of the panel inset and 3/4" from the bottom
5. Secure the mounting bracket to the panel using the cap screw, lock washer, and nut provided.
NOTE: If the truck has a cross member directly
behind the rocker panel, drill through both the
panel and cross member. The bottom lip of the
cross member will have to be cut and straightened
to provide bracket clearance.
6. Place the rear valance on the bracket. Open
the tailgate and adjust for clearance between the
bottom of the tailgate and the top of the valance.
7. Mark and drill the bracket holes on the backside of the valance.
8. Secure the valance to the bracket using the
bolts, nuts, and washers provided.
9. Line up the radius of the valance face with the
radius on the rear of the truck bed. It might be
necessary to bend the bracket slightly to make a
good fit.
10. Working at one end of the valance, mark a
mounting hole in the inside of the valance, 1" from
~the top. Then mark another hole approximately 2"
below the first.
11. After checking for tailgate clearance, mark
two similar holes on the opposite end of the
valance.
12. Pull out the ends of the valance and drill
5/16"-dlameterholes in the marked areas.
13. Replace the ends of the valance. Line up the
radius of the valance face with the radius on the
rear of the truck and mark the mounting hole
locations.
14. Drill the holes in the truck body; you might
have to remove the valance from the bracket to do
the drilling.
15. If the valance was removed in the previous
step, reinstall it on the bracket and realign with the
vehicle.
16. Secure the valance using the bolts, nuts, and
washers provided, but only finger tighten. Use
spacers as required. Check for tailgate clearance
and proper alignment, then tighten all bolts
securely.
Side Skirt installation

rear skirt.
18. Use a clean cloth and liquid grease remover
to clean the truck at the point of contact with the
top of the side skirts as well as the inside lip of the
skirts. It is important that these surfaces are very
clean so that tape adheres to them.
19. Cut the double-sided tape in 1' lengths.
Starting at the bottom of the larger radius of the
skirts and working toward the rear of the vehicle,
apply the tape to the side skirts just under and up
to the top lip.
20. Leave a 2" gap between pieces of tape and
continue taping the remainder of the side skirts.
21. After checking that the cab side skirt is in
alignment with the bottom of the door, remove the
tape cover and hold it to the side of the truck cab.

with the top and bottom of the cab skirt. Then remove the tape cover and press the tape firmly in
place along the entire length of the skirt.
23. Check the alignment of the bed rear skirt
with the truck side, then place a 3" strip of tape at
the back of the skirt to hold at the rear radius of
the truck just below the tailgate.
24. Remove the tape cover and press the tape
firmly in place along the entire length of the skirt.
25. Check all brackets, bolts, screws, and nuts
for tightness.
26. Repeat steps 6 through 25 on the opposite
side of the truck to complete the installation.
OFF-ROAD UPGRADE
Four-wheel-drive trucks can be upgraded for the
sport" of off-road driving. This includes the installation of oversized tires and lift kits. When it comes
to choosing an off-road tire, the one factor that
limits the size that can be used is clearance. It is
possible to put only so much tire under the fenders
before something starts to rub. Fender openings
can be enlarged to clear the extra rubber, and
easy-to-install cutout kits are available to hide the
surgery. Vet most people prefer a lift kit because it
provides extra clearance while raising ground
clearance at the same time. Another factor to keep
in mind is that when the size of your wheels and
tires is increased substantially, the unsprung
weight of the vehicle increases; this can lead to
unusual tire wear, handling changes, and reduced
life of the drivetrain components.
Note that all lift kits are not alike. Some are better engineered than others and are more complete.
For example, some kits consist of a set of springs
or blocks and nothing more; others include longer
U-bolts, steering arm, shocks, and shock mounting hardware. The more complete the kit,
the better the final result. The various lift kits on
the market come with complete installation instructions that should be followed explicitly. It's
wise to stay away from the more radical kits, as
they can be dangerous.
