Upper Shock Mounting Positions
The upper shock mounting positions will
have suspension effects opposite from the
lower shock mounting positions. Spring
rate (at the wheel) increases as the upper
shock mounting position is moved from
position (A) to position (C). Ride height is
not affected by changes in the upper shock
mounting position. Use the chart below to
see the effect of the various shock
mounting positions. The horizontal length
of the lines indicates the amount of suspension travel. The angle or slope
of the lines indicates the spring rate (at the wheel).
Shock Oil
The 4 oil-filled composite shocks (dampers) effectively control the
suspension movement by preventing the wheels and tires from
continuing to “bounce” after rebounding from a bump. Changing the oil
in the shocks can vary the suspension damping effect. Changing the oil
to a higher viscosity oil will increase damping. Lowering the viscosity of
the oil will cause the suspension damping to be reduced. Damping
should be increased (with higher viscosity oil) if the model is bottoming
easily over jumps. Damping should be decreased (with thinner viscosity
oil) if the model is hopping over small bumps and feels unstable. The
viscosity of shock oil is affected by extremes in operating temperature;
an oil of certain viscosity will become less viscous at higher temperatures
and more viscous at lower temperatures. Operating in regions with cold
temperatures may require lower viscosity oil. From the factory, the
shocks are filled with SAE-30W silicone oil. Only use 100% silicone oil in
the shock.
Replacing Shock Oil
For easier service, the shocks should be removed from the vehicle
and disassembled to change the oil.
1. Remove the lower spring
retainer and shock spring.
2. Remove the upper shock cap
using the shock wrench and
suspension multi tool.
3. Empty the used shock oil from
the shock body.
4. Fill the shock with new silicone
shock oil up to the top of the shock body.
5. Slowly move the piston up and down (always keeping it submerged in
oil) to release the air bubbles. Let the shock sit for a few minutes to
allow any remaining air bubbles to surface.
6. Slowly thread the upper cap with the installed shock bladder onto the
shock body with the suspension multi tool. The excess oil will bleed
out of the small hole in the shock cap.
7. Tighten the shock cap until snug. Use the included steel shock wrench
to hold onto shock body while tightening.

Basic Tuning Adjustments
Important: The shocks are
assembled at the factory
with a center-to-center
distance (between the
rod end balls) of 87mm.
Any time the shocks are
removed and disassembled,
this distance should be
checked to ensure
proper operation of
the suspension.
