This is the Traxxas TRX-4 Sport 4WD RTR Rock Crawler Trail Truck. The TRX-4 Sport combines the
unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon Trail tires,
and a lightweight pickup truck body for a leaner, performance-focused new TRX-4. The Sport?s unique
bumpers, wheels, and body were designed for increased climbing versatility. Whether it?s a fun trail
run or a hardcore technical crawl, the TRX-4 Sport?s capability and performance-built approach takes
your outdoor adventure to a new level. Just add a battery and charger to be ready to take on the world!


Outfitted with radically innovative technology, the TRX-4 Sport minimizes weight to maximize

The Power of Portals

Portal axles lift the truck at the wheels for huge center pumpkin ground clearance. In order to achieve
the same clearance with straight axles, your tires would have to be over an inch taller than the tires on
the TRX-4 Sport.

Heavy Duty Steel Frame Rails: A thick 1.5mm steel ladder frame with molded cross members provides
exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid
backbone lets the suspension do the work it was designed to do. You?ll feel the difference on trails
where the elimination of chassis flex allows for precise wheel placement when navigating technical

Adjustable Wheelbase

The innovative shock towers allow four separate ?bolt-on? wheelbase positions: 300, 312, 324, and
336mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and
adjustable shock position.

Molded Wire Retainers

The finer details matter so we incorporated wire retainers into the frame rails, which provide a clean look
and keep the wiring more secure from off-road hazards.

Dual-Fit Battery Tray

Tactical Unit?s dual-fit battery tray offers extreme flexibility when choosing batteries. For extended run
times, the large upper tray accommodates a full-length 5000 mAh 3-cell LiPo or 7600 mAh 2-cell LiPo.
A hinged battery strap provides quick and secure battery mounting without pins to lose in the field. The
innovative strap flips over to adjust for different height batteries. A smaller integrated tray accepts
smaller Traxxas batteries (that fit our 1/16 scale models) for increased forward weight bias.

Floor Pans

Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of
the chassis.

Aluminum Scale Shocks

All new oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out
even the roughest trails. These silver-anodized aluminum shocks deliver silky-smooth damping and
feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and
they perform even better with an O-ring cap seal and dual X-ring shaft seals.

Heavy Duty Steel Links

Thick 5mm diameter steel links feature tough, fully-captured heavy-duty rod ends with steel hollow balls
for exceptional strength and durability. This is one rig that won?t strand you on the trail with a broken
suspension link.

Precision Hex Hardware

The Tactical Unit uses tough hex hardware throughout for improved strength and easy servicing.
