A thick 1.5mm steel ladder frame with moulded 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.

Conventional crawlers equipped with axle spools sacrifice turning radius for traction. Traxxas 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.

The TRX-4's main battery tray accommodates the full-length Traxxas 5000mAh 3-cell LiPo or 7600mAh 2-cell LiPo for extended run times. Securely mount full-size LiPo batteries for extended runtimes, or opt for smaller 1/16 scale Traxxas batteries for reduced weight and improved agility. The innovative hinged battery strap eliminates the need for pins, ensuring quick and secure battery changes in the field. The strap even flips to adjust for batteries of different heights.

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. The 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.

Dominate any obstacle with the TRX-4's massive Titan 21T motor. This powerhouse delivers unmatched torque to power through challenging terrain. An integrated cooling fan ensures extended runtimes and peak performance, even under heavy loads.

The TRX-4's innovative shock towers unlock a world of customisation with four selectable wheelbase positions: 300, 312, 324, and 336 mm. This versatility ensures a perfect fit for your chosen body, enhancing both performance and aesthetics. Take customisation even further with adjustable shock positions and axle links for the ultimate personalised setup.

The TRX-4's design extends to the finer details. Wire retainers integrated into the frame rails keep wiring organised, protected, and out of harm's way during off-road adventures. Enjoy a clean, clutter-free look and peace of mind knowing your electronics are safe.

The TRX-4's oil-filled coil-over GTS shocks deliver unparalleled performance on any terrain. These anodised aluminium shocks provide silky-smooth damping and feature threaded bodies for easy ride height adjustments. O-ring cap seals and dual X-ring shaft seals ensure long-lasting, leak-free performance, while the scale realism adds to the TRX-4's impressive looks.

The TRX-4's suspension links are built to last. Thick 5 mm steel links with fully-captured heavy-duty rod ends featuring steel hollow balls deliver unmatched strength and durability. Conquer the toughest trails with confidence, knowing your suspension won't let you down.

The TRX-4's tough floor pans provide an extra layer of protection for your valuable electronics, safeguarding them from the harsh elements of off-road driving. These detailed floor pans also enhance the scale appearance of the chassis, adding a touch of realism to your RC experience.

The TRX-4 utilises tough hex hardware for enhanced strength and hassle-free maintenance. For those tackling the most extreme environments, consider upgrading to the Stainless Steel Hardware Kit (#8298) for ultimate durability.

The Traxxas TQi radio system enhances your driving experience with exclusive cruise control for effortless long-distance treks. Fine-tune your speed with the multi-function control, and seamlessly switch between high and low range gears using the grip-mounted rocker switch. Engage or disengage locking differentials with a separate toggle switch, all without interrupting your adventure. For ultimate convenience, the TQi is compatible with the Traxxas Link Wireless Bluetooth Module (#6511), allowing you to customise settings directly from your smartphone.

The TRX-4's full-metal geared digital servo provides the durability and precise steering control you need to tackle any terrain. Confidently navigate challenging obstacles and maintain control even in the toughest conditions.

The TRX-4 features and patented clipless body mounting system that not only allows quick and easy access to the chassis but also allows for an uninterrupted scale look on the shell.
