ChASSIS TUNING GUIDE
Shock springs are easy to change and can make a difference in the way your X-Terminator 2e handles relative to the type of terrain
you're driving on. If you drive your X-Terminator 2e off-road, in a smooth, high-traction area, use stiffer springs to reduce body roll and
weight shift. If the area where you drive your X-Terminator 2e is very bumpy, you might consider using softer springs to help absorb the
bumps. If the area is bumpy and you use harder springs, the X-Terminator 2e will have a tendency to jump and hop around. The shock
springs included with the X-Terminator 2e are suitable for most general off-road applications.

q Remove the shock, then carefully unscrew the shock cap. Pull the shock piston down
completely, then empty the shock oil from the shock. Fill the shock body with shock
oil until the oil level is just below the top of the shock body, then pump the shock
piston up and down several times to dissipate any air bubbles from the shock oil.
Top off the shock oil level if necessary, before reinstalling the shock cap. For more
information, see page 42.
Changing the shock oil will change the damping characteristics of the shocks. Typically, if you are running on smooth surfaces, use a
heavier weight shock oil. If you are running on rough surfaces, use a lighter weight shock oil.

Adjusting Shock Damping - Front and Rear
Use only 100% silicone oil in the shocks. Do not use motor oil.

We recommend using the 30 weight shock oil that the shocks are already lled with. For racing, you may want to consider using
35 ~ 40 weight shock oil.
q Remove the 3mm lock nut that holds the top of the shock in place, the pull the top
of the shock (and the bushing) off the shock mount.
q Unscrew the shock mount, then reinstall it into the new desired position, making sure
to tighten the cap screw rmly.
q Reinstall the bushing and shock. Firmly tighten the 3mm lock nut, then loosen it 1/2 a
turn to ensure the shock doesn't bind. Make sure to adjust the right and left sides equally.
The X-Terminator 2e shock towers feature a number of different mounting positions for the shocks. By changing the location of the upper
shock mounts you can make the shock feel stiffer or softer as the X-Terminator 2e rolls from side-to-side. In general, moving the shocks
toward the outside will make the shock stiffer and moving the shock toward the inside will make the shock softer.
You will need to experiment with these settings to nd something that suits both your track and driving style. A good starting point is
to adjust the rear shocks. Moving the rear shocks toward the outside will give more 'bite' (traction) in the turns. However, depending on
how you drive, you might want to move the shocks toward the middle. This will give a more 'plush' suspension.

We recommend initially leaving the shock mounting positions in the factory locations.
