TUNING ADJUSTMENTS

To achieve a good starting 
point for the slipper clutch, 
tighten the slipper clutch 
adjusting nut clockwise until 
the slipper clutch adjusting 
spring fully collapses (do not 
over tighten), and then turn 
the slipper clutch nut counter-
clockwise ¼ to ½ turn.

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 same 
at all four corners). Note that 
the groove in the hex indicates 
the side of the toe link with the 
left-hand threads. 

ALIGNMENT SETTINGS

Adjusting the Toe-in

Your E-Maxx comes from the factory with 

zero degrees of toe-in in the front, and 
one degree of toe-in in the rear. You can 
adjust the toe-in on the front and rear of 
the truck. Set the steering trim on your 
transmitter to neutral. Next, adjust your 
steering turnbuckles so that both front 
wheels are pointing straight ahead and 
are parallel to each other (0 degrees toe-
in). This will ensure the same amount of 
steering in both directions. Adjust the 
rear toe control links so that the rear 
wheels have 1˚ of toe-in.

Static Camber Adjustment

The wheels can be set to have either  
positive or negative camber (see 
illustration below). The camber angle changes 
as the wheel moves up and down through its 
range of travel. Static camber is the camber 
angle at the wheel when the vehicle is set at 
its normal, stationary ride height. 
The suspension pivot balls located in the axle 
carriers adjust the static camber. The pivot 
balls are protected by blue dust plugs. To 
adjust your static camber, insert the supplied 
2.5mm hex wrench through the slit in the 
dust plug and engage the end of the pivot ball (compressing the 
suspension until the arms are parallel to the ground will allow for 
easier hex wrench engagement). The upper pivot ball is normally 
screwed all the way in. Negative camber is achieved by screwing 
the pivot ball of the lower control arm out. 

Note:

 When camber is 

changed, the toe angle of the wheel has to be reset.

TRANSMISSION TUNING

Adjusting the Slipper Clutch

The E-Maxx is 

equipped with an 
adjustable Torque 
Control slipper 
clutch which is built 
into the large spur 
gear. The purpose 
of the slipper clutch 
is to regulate the amount of power sent 
to the rear wheels to prevent tire spin. When 
it slips, the slipper clutch makes a high-pitch, 
whining noise.  

To adjust the slipper clutch, remove the rubber 

slipper clutch plug on the transmission cover. The slipper clutch is 
integrated into the main spur gear on the transmission. The slipper 
clutch is adjusted using the spring-loaded locknut on the slipper 
shaft. Use the supplied universal wrench. To tighten or loosen the 
slipper nut, insert the 2.0mm hex wrench into the hole in the end 
of the slipper shaft. This locks the shaft for adjustments. Turn the 
adjustment nut clockwise to tighten (less slippage) and counter-
clockwise to loosen (more slippage). 

WHEELS AND TIRES

Many types of aftermarket tires and wheels can be adapted for 
use on your model. Most will affect the overall width and the 
suspension geometry of the model. The offsets and dimensions 
designed into the model’s wheels are intentional; therefore, 
Traxxas cannot recommend the use of other non-Traxxas wheels 
with different specifications. The diameter of the wheels is an 
innovative design, and there is a variety of different tires available 
for you to experiment with in addition to the included tires on the 
model (listed in your parts list). Experimentation with different 
types of tires is recommended to see which ones work the best on 
the terrain where the model is run. When selecting tires, consider 
the overall diameter and the rubber compound (hard or soft). If 
the overall diameter of the tire is significantly increased, you will 
need to use a smaller pinion gear to compensate for the larger tire. 
Soft compound tires with many short spikes generally work better 
on hard, dry surfaces. In loose dirt, a tire with large spikes should 
perform better. See your parts list for accessory wheels and tires.
