The TRX-4 Sport combines the unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon Trail tires, and a lightweight pickup truck body for a leaner, performance-focused new TRX-4. The Sport’s unique bumpers, wheels, and body were designed for increased climbing versatility. Whether it’s a fun trail run or a hardcore technical crawl, the TRX-4 Sport’s capability and performance-built approach takes your outdoor adventure to a new level!
The TRX-4 Sport differs from the TRX-4 Defender, Bronco and Tactical unit. Instead of remote locking differentials and two speed transmission, the TRX-4 Sport features full-time locked differentials and a single speed transmission. Other differences include a TQ-2 2-channel radio system instead of the TQ-i radio system included with the TRX-4 Defender, Bronco and Tactical unit.
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.
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.
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.
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.
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.
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.
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.
