ADJUSTING YOUR MODEL

Important: 

The shocks are 

assembled at the factory 
with a center-to-center 
distance (between the rod 
end balls) of 90mm. Any time 
the shocks are removed and 
disassembled, this distance 
should be checked to ensure  
proper operation of the 
suspension.

90mm

Adjustment procedures for alignment, spring rate, damping, steering, 
and ride height are covered here. 

SUSPENSION TUNING

Springs

TRX-4’s front springs (0.30 rate, white stripe) and rear springs (0.54 rate, 
green stripe) have been carefully selected to provide full suspension 
articulation and support for the weight of the vehicle body. 
Using different bodies with lighter weight will allow you to use lower 
rate springs to increase traction and suspension articulation when 
traversing difficult terrain. Lighter springs can be used since the portal 
axles use gear reduction to reduce undesirable torque twist. 

Ride Height Adjustment

TRX-4’s ride height can be finely tuned by adjusting suspension sag 
via the preload adjusters on the shock bodies. Thread the preload 
adjuster down the shock body to raise TRX-4’s ride height, or thread 
the adjuster up the shock body to lower ride height. The front left 
preload adjuster will require more threading to compensate for 
the weight of the motor. If threading the preload adjusters to the 
maximum ride height position still allows more suspension sag than 
you prefer, stiffer springs should be installed. 

SHOCK TUNING

Shock Oil

The 4 oil-filled aluminum shocks (dampers) effectively control the 
suspension movement. 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 or when stiffer springs are installed. Damping 
should be decreased (with thinner viscosity oil) if the model is hopping 
over small bumps and feels unstable or when softer springs are installed. 
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 20W silicone oil. Only use 100% silicone oil in the shock.

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.

3.  Empty the used shock oil from the 

shock body.

4.  Compress the shock fully against 

the stop on the lower spring 
retainer (A).

5.  Fill the shock with new silicone 

shock oil up to the top of the shaft; 
then, add 2-3 drops of oil to reach 
the proper level (0.3mm above the 
top of the shaft) (B). 

6. Slowly move the piston up and 

down to remove excess air. Add  
oil if needed to maintain the  
proper level.

7.  Ensure the cavity in the upper shock 

cap (C) is dry and free of oil; screw 
the shock cap onto the shock body. 

8. Tighten the shock cap until snug. 

Shock disassembly

The shocks must be removed from the vehicle prior to disassembly. 
Use the shock exploded views included with the model to aid in the 
assembly process.
1.   Remove the spring and lower spring retainer from the shock. 
2.   Remove the shock cap and empty the shock body of shock oil. 
3.  Remove the lower cap, the X-rings, and spacer from the shock 

body. 

4.   Use needlenose pliers or side cutters to grip the shock shaft just 

above the rod end. Remove the rod end from the shock shaft. 

5.   Remove the shock shaft with piston from the shock body out 

through the top of the shock body.
