TRX-4 1/10 Scale And Trail Crawler

Trail trucks are fast and nimble, but lack the off-road credentials to tackle a technical course. Dedicated crawlers power over obstacles, but their locked differentials and slow speeds make them boring on the trail. The all-new groundbreaking Traxxas TRX-4 Scale and Trail Crawler obliterates the line between trail rig and crawler.

Built the Traxxas way, the TRX-4 is rugged, powerful, and ready for fun on the trail or the crawling course. Remotely locking differentials, steep approach angles, and industry-first portal axles provide bona fide crawling credentials. Revolutionary Cruise Control and remotely operated high/low transmission make it a blast to drive on the trail. Why compromise when the TRX-4 Scale and Trail crawler lets you have it all?

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 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 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.

Improved Geometry

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. 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.

Metal Gear Digital Servo

A new full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through  tough situations.

Waterproof 

Traxxas was the first to bring you fully waterproof RC vehicles years ago with our 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.

Scale Detail 

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-wheelin’ 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.

Inner Fenders 

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.

Cruise Control 

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 new XL-5 HV electronic speed control brings 3S LiPo capability for stronger, more efficient running. New speed control profiles have been added for smooth and precise control. A new Trail profile facilitates smooth driving for most of your adventures, while a new 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!

Canyon Trail 1.9 Tires 

The 1.9 Canyon Trail tires and tuned foam inserts are super-soft and grippy to deliver superior bite on rocky surfaces with convincing scale realism. The 12mm steel hex drive makes the TRX-4 chassis compatible with popular 1.9 wheel and tire combinations.

Traxxas Tough 

Leave the tools in the bag! The Traxxas TRX-4 chassis is built to handle the rigors of remote locations and all-day driving fun. The foundation begins with a pair of 1.5mm thick steel frame rails. Large diameter steel links and heavy-duty, extra-wide rod ends keep the suspension firmly mounted. Hardened steel CV-style half-shaft joints are ultra reliable, while the brushless-ready steel portal axle and transfer case gears are smooth and quiet. Traxxas’ composite materials have been refined over three decades for the ultimate in strength and durability.

Aluminum GTS Shocks 

All new oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis. These silver-anodized aluminum units deliver silky-smooth damping performance and feature threaded shock bodies for easy ride height adjustments. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.

Extreme Capability 

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.
