TRX-4 Technology and Innovation Now Available as a Kit!
The Traxxas TRX-4 Scale and Trail Crawler set the standard for off-road versatility with its radical design and rugged durability. The new TRX-4 chassis kit combines the same innovative features as the RTR vehicle with the fun and excitement of building your own kit. Build your own portal axles, high/low range transmission, and remotely locking differentials. All the parts are organized neatly in labelled bags with waterproof electronics and pre-assembled shocks and suspension links. A fully illustrated colour manual makes the kit as much fun to construct as it is to take off-road.
Easy to Follow Assembly Instructions
The TRX-4 Chassis Kit isn’t just for expert hobbyists. Traxxas goes the extra mile to make the full-colour instruction book easy to follow and fun to use. Each section corresponds to a labelled bag with step-by-step assembly instructions. True-to-scale part illustrations and ruler charts make it easy to differentiate between different screws, bearings, and gears. Helpful assembly tips and clear illustrations take the frustration out of the assembly process. Have fun on the workbench and on the trail with the new TRX-4 Chassis Kit.
Ultimate 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 centre 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 travelled 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 centre 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. 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.
45° Steering Angle
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
Hi/Low Range Transmission
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.
The TRX-4 Trail and Scale is being shown with the legendary Land Rover Defender body, complete with exciting scale details for an authentic 4-wheeling experience. We’ve included a functional spare wheel and tire, an off-road jack, and spare fuel canisters. Secure your trail gear in the included roof basket. There’s even a snorkel for taking the waterproof TRX-4 through creek crossings. The rugged bumpers provide clearance and protection and are equipped with recovery D-rings. The front bumper is designed to be compatible with many popular off-road accessories
The scale details did not stop with the body. We went underneath to install detailed inner fenders that integrate with the scale look of the floor pans and shock towers, keeping rocks, mud, and twigs out of the chassis. The inner fenders are also equipped with pockets to install our optional LED rock light kit (sold separately) to light up the night trail, casting light right where it’s needed. The rock lights make changing a “flat tire” on the trail a breeze! Integrated rock sliders help protect the body from damage.
