TUNING ADJUSTMENTS
acceleration by reducing engine rpm loss when shifting from 1st gear to
2nd gear. The wide ratio gear set is designed for wide open areas and will
increase top speed, but reduce acceleration due to greater rpm loss when
shifting gears.
BRAKE SETUP & ADJUSTMENT
T-Maxx 3.3 is equipped with a disc brake that rides on the yoke of the
transmission's front output shaft. The brake is preset at the factory
and should not require attention. As the brake material wears, future
adjustments may be necessary.
Brake Shoulder Screw Adjustment
The two shoulder bolts that are used to secure the brake pads to the
transmission housing may need to be adjusted periodically as the brake
material wears down. They should be tightened so a 0.50mm (.020") gap
exists between the disc and the brake pad (on the transmission side).
Adjust in one of the following ways:
1. Use a .50mm feeler gauge between
the brake pad insert and brake disc.
2. Push the outer brake pad firmly
against the inner pad with your
finger, sandwiching the brake disc
between the brake calipers. Tighten
the brake shoulder bolts until they just barely touch the brake pads. Do
not over tighten these fasteners or you could damage the brake calipers.
Loosen each of the shoulder bolts by 1 turn.
Brake Pad Wear and Replacement
During normal use the brake pads should wear at a relatively slow rate.
However, if the brake pads wear down close to the metal pad holders, they
should be replaced. Any more wear than this could cause damage to the
brake parts and improper operation of the brake system.

Position 4 (no wheelies)
The top position on
cross bars. Offers the
flattest launches with
little or no wheelie.
This is the factory
installed position
to reduce wheelies
during break-in.
Position 3

Position 1 (big wheelies)
Bottom position on
cross bars. Allows
the truck to tip back
the furthest during
a wheelie for longer,
high-speed wheelies.
Wheelie Bar Installation
The Maxx Wheelie Bar can be used on any Maxx truck with the
stock rear skid plate, rear bumper, and rear bumper mounts.
It is also compatible with the Traxxas accessory aluminum rear
bumper (part #4935X). The wheelie bar is intended for use on hard,
high-traction surfaces, such as pavement, where controlling wheelies
can be difficult. It is easily removed for off-road racing or jumping.
1. Slowly bend the end of the skid plate downward, and then key the
skid plate into the slot of the wheelie bar.
2. Slide the wheelie bar down to the bottom of the skid plate,
and then snap the clip over the lower bumper tube.
3. Removal is opposite of installation. Snap the wheelie bar off of the
bumper, and then slide the wheelie bar off of the skid plate.
Wheelie Bar Setup Instructions
Changing the position of the wheelie
bar height setting is easier when
the wheelie bar is installed on the
truck. Snap the upper arms off of the
wheelie position cross bars. Move the
upper arms to the desired wheelie
position cross bar and then snap them
in place.
Each setting can offer different results based on the individual ride
height and droop settings for a particular truck. Try to avoid riding on
the wheelie bar wheels during normal driving (this can happen in the
lowest setting with lower than stock ride heights).
Remove the wheelie bar when the T-Maxx will be jumped or driven in
harsh off-road conditions.
