Adjusting the Toe-in
Geometry and alignment specs
play an important roll in your
model's handling. Take the time
to set them correctly. 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 1°-2° of toe-in to
each front wheel. Use the turnbuckles to adjust the alignment.
Adjusting the Camber
0°
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° of camber.

In the rear, the stock camber is
-1.5°. 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 in turns. Proper setup will add stability
and help prevent spin outs. Experiment with different springs and shock

Shock Mounting Positions
Big bumps and rough terrain require a

softer suspension with the maximum
possible suspension travel and ride height.
Toe-in
Racing on a prepared track or on-road use
requires a lower ride height and firmer, more
progressive suspension settings. The more
progressive suspension settings help reduce
body roll (increased roll stiffness), dive during
braking, and squat during acceleration.
