TUNING ADJUSTMENTS

decreased by installing different rocker arm sets. The rockers are labeled 
Progressive 1 to Progressive 3. Progressive 1 rockers will provide a low 
progressive rate that maintains consistent damping force across the 
whole range of suspension travel. Progressive 2 rockers provide a larger 
degree of rate change, and Progressive 3 rockers have the greatest rate 
difference. Progressive 3 rockers will improve high-speed cornering on 
smooth surfaces by providing a firmer feel. Remember that Progressive 
1, 2, and 3 rockers all provide 90mm of travel, 30mm less than the 
Summit’s stock 120mm long-travel rockers. This may improve road 
handling, but will reduce suspension articulation in rough terrain.  Body 
roll, brake dive, and rear squat will also be reduced. Always change all 
four rockers as a complete set. Do not mix rates and travel. 

When using the Progressive 1, 2, or 3 rockers, Traxxas #5439 springs  
(3.8 rate gold) provide a good starting point for suspension tuning.

The chart below demonstrates the effect of the various rocker arms on 
wheel force as the suspension is compressed. On the progressive rate, 
wheel force is light at first and increases as the suspension is compressed.

SHOCK TUNING

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-
50W 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  

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 the shock body while tightening.

Shock Pistons

The shock pistons can be replaced with the available optional pistons to 
vary the amount of damping. Optional pistons with bypass holes that 
are larger or smaller (1, 2, or 3) than the factory-installed stock pistons 
can be used to decrease or increase damping respectively. Change the 
pistons if you only have one weight of shock oil available to you. From 
the factory, Summit is equipped with #2 pistons in the front and #2 
pistons in the rear.

Multi-tool Shock Functions

All of the toe links are installed 
on the truck so that the left-
hand thread indicators point 
to the same direction. This 
makes it easier to remember 
which way to turn the wrench 
to increase or decrease toe 
link length (the direction is the 
same at all four corners). Note 
that the groove in the hex 
indicates the side of the toe 
link with the left-hand threads. 

A camber gauge (available  
at your local hobby shop) 
can be a useful tool for 
alignment setting.
