ADJUSTING YOUR MODEL
Once you become familiar with driving your model, you might
need to make adjustments for better driving performance.
Adjusting the Toe-in
Geometry and alignment
specs play an important role
in your model’s handling.
Take the time to set them
correctly. Turn off TSM
(see page 17); then, set the
steering trim on your transmitter to neutral. Now, adjust your servo and
tie rods so that both wheels are pointing straight ahead and are parallel
to each other (0° toe-in). This will ensure the same amount of steering in
both directions. For increased stability, add one- to two-degrees of toe
in to each front wheel. Use the turnbuckles to adjust the alignment.
Adjusting the Camber
The camber angle of both
the front and rear wheels can
be adjusted with the camber
rods (upper turnbuckles).
Use a square or right-angle
triangle to set the camber
accurately.
The stock camber of the
front wheels is -1 degree of
camber. In the rear, the stock
camber is 0 degrees. These
adjustments should be set
with the truck positioned at
its normal ride height with a
battery installed.
Fine Tuning the Shocks
The four shocks on the model greatly
influence its handling. Whenever you
rebuild your shocks or make any changes
to the pistons, springs, or oil, always make
changes to them in pairs (front or rear).
Piston selection depends on the range of
oil viscosities that you have available. For
example, using a two-hole piston with a
lightweight oil will, at one point, give you
the same damping as a three-hole piston
with heavier oil. We recommend using
the two-hole pistons with a range of oil
viscosities from 10W to 50W (available from
your hobby shop). The thinner viscosity oils
(30W or less) flow more smoothly and are
more consistent, while thicker oils provide
more damping.
Use only 100% pure silicone shock oil to prolong seal life. The
model’s ride height can be adjusted by adding or removing the
clip-on, spring preload spacers. Adjust the ride height so that the
suspension arms are slightly above being parallel to the ground.
Observe how the model handles when launching. Proper setup will
add stability and help prevent swerving to one side or the other or
vehicle drifting. Experiment with different springs and shock oils to
find what works best for your current track conditions.
Shock Mounting Positions
The factory suspension settings help reduce throttle-induced
steering and allow weight to transfer to the drive wheels, giving
a better launch. Your model’s suspension has been factory set for
the best drag racing performance out of the box and should not
require adjustment.

Toe-in
All of the toe links are installed
on the truck so the left-hand
thread indicators point to the
same direction. This makes it
easier to remember which way
to turn the wrench to increase
or decrease toe link length
(the direction is the same at
all four corners). Note that the
groove in the hex indicates
the side of the toe link with
the left-hand threads.
