TRX-4® Sport combines the unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon Trail™ tires, and a clipless lightweight pickup truck body for a leaner, performance-focused truck. 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.
New to TRX-4 Sport, clipless body mounting combines clean flowing lines with secure latching convenience. TRX-4 Sport’s hidden latches hold tight on the trail no matter how intense the action gets, but release in just seconds to access the chassis.
Outfitted with radically innovative technology, TRX-4 Sport minimizes weight to maximize performance.
Portal axles lift the truck at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles, your tires would have to be over an inch taller than the tires on TRX-4 Sport.
The portal axles use gear reduction at the wheels to virtually eliminate torque twist. The Titan 550 motor’s torque translates into straight, powerful, forward motion, rather than wasted energy twisting your rig right off the rocks.
When negotiating a slick rock face or powering through a mud bog, traction is king. TRX-4 Sport comes outfitted with differential spools in the front and rear for ultimate grip when you need it most.
Geared for raw torque, the single-speed transmission sheds valuable weight from the Sport’s chassis for better weight distribution. Steel gears provide Traxxas-Tough durability and virtually maintenance-free operation.
The TRX-4 Sport tramples the status quo with extreme versatility and off-road capability. Performance and technology combine in a revolutionary new chassis that looks as good as it performs.
A heavy-duty formed-steel ladder frame with molded cross members creates an extremely rigid backbone. You’ll feel the difference on trails when navigating technical terrain.
Oil-filled coil-over GTS shocks deliver silky-smooth damping performance and feature threaded aluminum shock bodies for easy ride height adjustments. The convincing scale realism looks great and they perform even better.
The XL-5™ HV electronic speed control brings 3s LiPo capability for strong efficient running. The powerful 21T Titan® motor provides torque to tackle the steepest climbs and all-out speed on flat terrain. This efficient system provides up to 2 hours of run time with a Traxxas 3s 5000 mAh LiPo battery pack!
Comfortable and precise, the easy-to-use TQ radio system features the reliability you expect from Traxxas. The TQ’s advanced programming provides long-range control with smooth, glitch-free performance.
TRX-4 is fully waterproof, 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.
Designed for ultimate all-terrain performance, TRX-4 Sport’s lightweight body keeps the CG low for improved stability when climbing and clipless mounting ensures the body stays secure. Low-profile bumpers increase the approach and departure angles while red differential covers and D-rings add off-road style.

A thick 1.5 mm steel ladder frame with molded 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 336 mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.
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.
TRX-4’s main battery tray accommodates a full-length 5000 mAh 3-cell LiPo or 7600 mAh 2-cell LiPo for extended run times or smaller 1/16 scale Traxxas batteries for reduced weight. 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.
Tough floor pans protect the electronics and enhance the scale appearance of the chassis.
Oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out even the roughest trails. These silver-anodized aluminum 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.
Thick 5 mm diameter steel links feature tough, fully-captured heavy-duty rod ends with steel hollow balls for exceptional strength and durability. This is one rig that won’t strand you on the trail with a broken suspension link.
TRX-4 uses tough hex hardware throughout for improved strength and easy servicing. For extreme environments, consider using the Stainless Steel Hardware Kit 8298.
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.
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. TRX-4’s portal axles 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.
Full-time locked front and rear differentials transform the motor’s torque into unstoppable climbing action. With no slippage possible, all four wheels claw with equal traction, powering the lightweight Sport over the toughest obstacles.
The single-speed transmission is geared low for the raw torque required to scale the steepest grades. Steel gears provide the Traxxas-Tough durability that keeps you on the trail.
Hardened steel U-joints on the front and rear driveshafts provide smooth, reliable power delivery for non-stop fun.
A twin friction plate slipper clutch provides some additional protection from motor stalls in extreme crawling conditions.
Black sealed ball bearings resist mud and dirt to keep your rig rolling smoothly.
TRX-4’s portal axles raise the driveshafts higher to improve axle geometry and reduce driveshaft angles. Higher driveshafts and suspension links pass over obstacles to avoid high-centering your truck and reduce overall grinding wear.
The steering link and drag link attach high on the portal axles, raising them away from possible damage. This allows TRX-4 to attack obstacles head on, reducing the risk of hitting the steering linkage on rocks.
The superior 45° steering angle negotiates around even the tightest bends with ease. This helps avoid awkward reversing maneuvers in tight spaces.
With a 58.82° out-of-box approach angle in the front, TRX-4 is ready to climb walls. An equally impressive 45.83° rear approach angle provides extreme capability, even in the deepest ruts.
Portal axles help raise the center ground clearance to an unparalleled 3.14 inches (80 mm), while raised suspension links and driveshafts clear the rocks underneath. Superior capability equals more fun no matter where your adventure takes you.
TRX-4’s large 550 size brushed 21-turn Titan motor provides smooth reliable power and loads of torque to climb the toughest obstacles. The front mounted orientation moves the weight bias forward to get you up and over obstacles with improved traction.
HV stands for compatibility with the high-voltage 3s LiPo battery packs for greater efficiency and power. In addition to the three standard profiles (Sport, Race, Training Mode™), the XL-5 HV features a Trail profile that serves up a little bit of drag brake for smooth intuitive driving for most of your adventures. The Crawl profile introduces hill hold and instant reverse for extremely technical courses. Either will help you navigate the trail with ease.
Torque rules the trail and TRX-4’s massive Titan 21T motor pumps out huge torque to get you up and over anything that gets in the way. An integrated cooling fan keeps temperatures down for extended run times.
A full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough challenges.
Switch on the power and drive! That’s all there is to it with the TQ™ 2.4 GHz radio system. Race multiple vehicles side by side without interference. The TQ’s advanced programming provides long-range control with smooth, glitch-free performance and it fits comfortably in the hand for extended use.
