The Traxxas TRX-4 Scale and Trail Crawler is an all-new Traxxas design that is loaded with innovation that instantly obsoletes the status quo with exciting new features, versatility, and capability. In other words, we built it the Traxxas way, rugged, powerful, and ready for fun!
Underneath the authentic scale look is a machine built for extreme off-road capability that takes you to new places and new adventures. Exclusive portal axles deliver maximum ground clearance that dramatically turns “no way” into “no problem.” Whether you are enjoying outdoor trails or getting technical on the rocks, the remote-locking front and rear differentials and high/low range transmission provide unmatched driving versatility.

Product VideosUltimate Ground Clearance:
The TRX-4 Scale and Trail Crawler is equipped right out of the box with Traxxas' game-changing portal axle set. Portal axles lift the truck at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles (and not get stuck), your tires would have to be over an inch taller than the TRX-4's tires. Straddling boulders with ease, the TRX-4 chassis definitely takes the path less traveled and simply leaves all the others behind.
Torque Twist Eliminated:
The portal axles use gear reduction right at the wheels that dramatically reduces undesirable torque twist. Total axle gear reduction is over twice non-portal designs. The Titan 550 motor torque is translated into straight, powerful, forward motion, rather than wasted energy twisting your rig right off the rocks.
Portal axle geometry raises the axle link mounts and center driveshaft, greatly reducing critical driveshaft and suspension link angles. This means less strain on the driveshafts, and the higher suspension links provide greater clearance with less scraping and dragging across the rocks. The steering drag link and tie rod are also raised up and out of harm's way.
Rigid Steel Frame:
A heavy-duty formed-steel ladder frame with molded cross members creates an extremely rigid backbone that 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.
Remote Locking Differentials:
Traxxas gives you the versatility to lock and unlock the front and rear differentials to suit your driving needs directly 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, for superior grip over extreme terrain. This patented design has been proven rugged and capable in the Traxxas Summit. Sleeved micro cables control the differential action for scale appearance, without limiting the huge suspension articulation.
Traxxas was the first to bring you fully waterproof RC vehicles years ago with their innovative designs. The TRX-4 Scale and Trail Crawler is fully waterproof for how you like to really play, 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.
The Traxxas TQi radio system is equipped with 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 precisely match the pace of your caravan of trail explorers. Cruise control makes it easy and comfortable for the TRX-4 Scale and Trail Crawler to be your companion for hours of driving fun and exploration.
3S Power System:
The XL-5 HV electronic speed control brings 3S LiPo capability for stronger, more efficient running. Updated speed control profiles have been added for smooth and precise control. A Trail profile facilitates smooth driving for most of your adventures, while a Crawl profile introduces hill hold and instant reverse for extremely technical courses. Either will help you navigate obstacles with ease, right from the start. Long run times, up to 2 hours, are possible with a Traxxas 3S 5000mAh iD LiPo battery pack!
Steep approach angles front and rear allow the TRX-4 Scale and Trail Crawler to tackle big obstacles head on. The front motor design biases weight forward for superior climbing ability compared to other designs.
