The ride height of the model
can be changed by mounting
the push rod in a different hole
in the lower suspension arm.
From the factory, the push rod
comes installed in the center
hole of the lower suspension
arm’s push rod mount. If the
push rod is mounted in the inner hole, the ride height of the vehicle
increases. If mounted in the outer hole, the ride height decreases.

The ride height can be finely tuned by adjusting the sag of the
suspension. 

Do not attempt to make large changes to the ride height

by adjusting the spring pre-load on the shock bodies.

If suspension sag

is severe and requires a large increase of the spring pre-load to
compensate, then a firmer spring should be used. The lowest ride height
can be achieved by installing the optional adjustable push rod in the
outermost hole of the lower suspension arm’s push rod mount. Turn the
rod ends all the way in until they stop (shortening the length).

The optional Long Travel rocker arms are designed to be used only with
the standard non-adjustable push rods installed in the hole labeled “LT”
(the middle hole of the lower suspension arm’s push rod mount). Any
minor adjustments to the ride height are accomplished by adjusting the
spring pre-load.

Adjusting the Pivot Ball Caps

The pivot ball caps should be
adjusted so that the pivot balls
operate freely in the axle carriers with
no excess play. Use the provided four-
way suspension multi-tool to tighten
or loosen the pivot ball cap.

Shock Oil

The 4 oil-filled aluminum 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.

For shock piston tuning see Advanced Tuning Adjustments on page 44.

Replacing Shock Oil

The shocks have to 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 the
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.
