Changing the shock oil (the oil inside the shocks) will change the damping characteristics of the shocks. Typically, if you are running on
smooth surfaces, use a heavier weight oil. If you are running on rough surfaces, use a lighter weight oil.
# 400 (40 weight) shock oil is stock. This is good for all-around use. For racing, you may want to consider using # 250~# 500
(25~50 weight) shock oil.
The front upper hinge pins can be moved up or down to adjust bump steer. Generally, if you move the hinge pins into a lower position,
this will increase bump steer, which can be helpful on tight tracks. For a larger track, you may want to move the hinge pins to a higher
position to decrease bump steer.
l
We recommend initially leaving the front upper hinge pins in the factory locations.
q Adjust
bump steer by removing the upper hinge pins and reinstalling them, along with
the upper suspension arms, in a hole either further up or lower down in the upper
suspension plate.
RECOMMENDED INITIAL SETTINGS
IMPORTANT: When tightening the hex nuts on the back of the hinge pins, be careful not to overtighten them or the suspension
arms may not pivot freely. When adjusting the hinge pin positions, make sure to adjust the right and left sides equally.
The XST 4WD Truggy RTR 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 XST 4WD Truggy RTR 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.
l
We recommend using the # 400 shock oil that the shocks are already lled with.
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, gently pump the shock
piston up and down to dissipate any air bubbles from the shock oil. Top off the shock
oil level if necessary, before reinstalling the shock cap and diaphragm.
RECOMMENDED INITIAL SETTINGS
l
We recommend initially leaving the shock mounting positions in their factory locations.
q Change the shock mounting positions by rst removing the top of the shock from the
shock mount, then by removing the shock mount from the shock tower. Reinstall the
shock mount, then the top of the shock into the desired position on the shock tower.
Make sure to adjust the right and left sides equally.
RECOMMENDED INITIAL SETTINGS
IMPORTANT: Use only 100% silicone oil in the shocks. Do not use motor oil.
