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 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.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 travelled and simply leaves all the others behind. 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.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.
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. Our patented design has been proven rugged and capable in the Traxxas Summit. New sleeved micro cables control the differential action for scale appearance, without limiting the huge suspension articulation.Traditional crawlers sacrifice turning radius for traction. The TRX-4’s remote locking differentials disengage to take full advantage of its superior 45 degree steering angle. Once you clear the obstacle, re-engage the differentials for ultimate traction.
When the going gets tough, use your transmitter to shift into low range for incredible 4-wheel drive pulling torque. Shift into high range for blasting down the trail. The plush suspension design absorbs rough terrain with ease and delivers outstanding scale appearance. Unmatched versatility makes the TRX-4 Scale and Trail Crawler adaptable to just about any situation or driving style.
