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.
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?

Heavy Duty Steel Frame Rails
A thick 1.5mm steel ladder frame with moulded cross members provides exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid backbone 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.
The innovative shock towers allow four separate "bolt-on" wheelbase positions: 300, 312, 324, and 336mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.
Moulded Wire Retainers
The finer details matter so we incorporated wire retainers into the frame rails, which provide a clean look and keep the wiring more secure from off-road hazards.
Dual-Fit Battery Tray
TRX-4's dual-fit battery tray offers extreme flexibility when choosing batteries. For extended run times, the large upper tray accommodates a full-length 5000 mAh 3-cell LiPo or 7600 mAh 2-cell LiPo. A hinged battery strap provides quick and secure battery mounting without pins to lose in the field. The innovative strap flips over to adjust for different height batteries. A smaller integrated tray accepts smaller Traxxas batteries (that fit our 1/16 scale models) for increased forward weight bias.
Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of the chassis.
Aluminium Scale Shocks
All new oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out even the roughest trails. These silver-anodized aluminium shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.
Exclusive to the TRX-4, portal axles lift the differential pumpkin to provide incredible ground clearance. This radical design also improves axle geometry and reduces strain on the driveshafts. Steel gears ensure trouble-free performance, no matter how technical the climb.
Torque Twist Eliminated
On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. The TRX-4's radical portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis. Total axle gear reduction is over twice non-portal designs so Titan motor torque delivers smooth forward motion, not frame twist.
T-Lock Remote Locking Diffs
Conventional crawlers equipped with axle spools sacrifice turning radius for traction. Traxxas gives you the freedom and versatility to lock and unlock both the front and rear differentials to suit your driving needs, all controlled remotely 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 differential, for superior pull and 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.
Why carry your crawler down the trail when you can drive? The TRX-4 features a high speed gear to get you to your next crawling challenge quickly. When you get there, flip the rocker switch on your transmitter to engage low range and conquer tough terrain with exceptional torque.
Hardened Steel U-Joints
Hardened steel U-joints on the front and rear driveshafts provide smooth, reliable power delivery for non-stop fun.
Twin Friction Plate Slipper Clutch
The TRX-4's twin friction plate slipper clutch provides some additional protection from motor stalls in extreme crawling conditions.
Raised Centre Driveshaft and Suspension Links
TRX-4's radical portal axle design raises the driveshafts higher to improve axle geometry and reduce driveshaft angles. Higher driveshafts and suspension links pass over obstacles to avoid high-centreing your truck and reduce overall grinding wear.
