Innovation
Radically innovative technology combines with precision engineering to create a breed of Scale and Trail® Crawler…Only from Traxxas.
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 TRX-4.
Torque Twist Eliminated
The portal axles use gear reduction at the wheels to virtually eliminate torque twist. The Titan® 550 motor’s torque translates into straight, powerful, forward motion, rather than wasted energy twisting your rig right off the rocks.
All-New Chassis Design
TRX-4 instantly obsoletes the status quo with greatly expanded features, versatility, and capability. Performance and technology combine in a revolutionary new chassis that looks as good as it performs.
Rigid Steel Frame
A heavy-duty formed-steel ladder frame with molded cross members creates an extremely rigid backbone. You’ll feel the difference on trails when navigating technical terrain.
Scale Details
TRX-4 features a fully licensed and highly detailed Land Rover Defender body. Scale details abound from the detailed front grille and bumper to the functional spare tire in the back. Realistic lighting details, side mirrors, bumpers and even the included jack all add to the rugged and authentic appearance.
Remote Locking Differentials
Traxxas allows you to lock and unlock both the front and rear differentials remotely from your transmitter. New sleeved micro cables control the differential action for scale appearance, without limiting suspension articulation.
GTS Aluminum Shocks
Oil-filled coil-over GTS shocks deliver silky-smooth damping performance and feature threaded aluminum shock bodies for easy ride height adjustments. The convincing scale realism looks great and they perform even better.
High/Low Range Transmission
When the going gets tough, shift into low range for incredible 4WD pulling torque. Shift into high range for blasting down the trail. The TRX-4 Scale and Trail Crawler adapts to any situation or driving style.
3S Power System
The new XL-5™ HV electronic speed control brings 3s LiPo capability for stronger, more efficient running. The powerful 21T Titan® motor provides torque to tackle the steepest climbs and all-out speed on flat terrain. This efficient system provides up to 2 hours of run time with a Traxxas 3s 5000 mAh LiPo battery pack!
TQi Radio System with Cruise Control
The Traxxas TQi™ features our exclusive cruise control for long-distance treks. Set your speed using the transmitter and then use the multi-function knob to fine-tune it faster or slower to match precisely the pace of your caravan of trail explorers.
Accessory Light Kits
Optional light kits illuminate the trail ahead and provide an authentic appearance. A separate regulated power supply ensures powerful lighting with consistent brightness.
(All light kits and light kit accessories are sold separately.)Waterproof Electronics
TRX-4 is fully waterproof, not “splash resistant.” There is a big difference. Traxxas’ patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water in your electronics.

Portal Axles
TRX-4's portal axles lift the differential pumpkin to provide incredible ground clearance. This radical design also improves axle geometry and reduces strain on the driveshafts. Steel gears ensure trouble-free performance, no matter how technical the climb.
×
Torque Twist Eliminated
On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. TRX-4’s radical portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis. Total axle gear reduction is over twice non-portal designs so Titan motor torque delivers smooth forward motion, not frame twist.
×
T-Lock Remote Locking Differentials
TRX-4 gives you the freedom and versatility to lock and unlock both the front and rear differentials to suit your driving needs, all controlled remotely from your transmitter. Leave the differentials unlocked for relaxed driving on the trail with smooth, tight turning and better handling at high speeds. When the trail gets technical, lock the front and rear differentials, or just the front differential, for superior pull and grip over extreme terrain.
×
High/Low Transmission
Why carry your crawler down the trail when you can drive? TRX-4 features a high speed gear to get you to your next crawling challenge quickly. When you get there, flip the rocker switch on your transmitter to engage low range and conquer tough terrain with exceptional torque.
×
Hardened Steel U-Joints

Heavy Duty Steel Frame Rails
A thick 1.5 mm 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 terrain.
×
Adjustable Wheelbase
The innovative shock towers allow four separate “bolt-on” wheelbase positions: 300, 312, 324, and 336 mm 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
TRX-4’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
Oil-filled coil-over GTS shocks smooth out even the roughest trails. These silver-anodized aluminum shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment.
