The legend is back. After 25 years, the Bronco has returned as Ford’s top-performing 4X4 and America’s most sought-after SUV. Traxxas has captured the eagerly-anticipated Bronco in exacting detail with all the capability and versatility of the award-winning TRX-4. The Traxxas Bronco combines Ford-approved realism and class-leading performance for exciting off-road adventure no matter where the trail takes you.
A thick 1.5mm 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.
A heavy-duty metal servo horn comes standard on the TRX-4 Bronco.
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 5000mAh 3-cell LiPo or 7600mAh 2-cell LiPo for extended run times. 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 secondary front-mounted battery tray accepts smaller 1/16 scale Traxxas batteries to position weight directly over the front axle for maximum climbing traction on technical climbs.
Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out 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 5mm 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.
The TRX-4 uses tough hex hardware throughout for improved strength and easy servicing.
Exclusive to TRX-series trucks, 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. 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.
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. 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 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 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-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 the TRX-4 to attack obstacles head on, reducing the risk of hitting the steering linkage on rocks.
With the front differential unlocked, the superior 45-degree steering angle negotiates around even the tightest bends with ease. This helps avoid awkward reversing maneuvers in tight spaces.
With a 52 degree out-of-box approach angle in the front, TRX-4 is ready to climb walls. An equally impressive 49 degree 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 (80mm), while raised suspension links and driveshafts clear the rocks underneath. Superior capability equals more fun no matter where your adventure takes you.
The 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.
The XL-5 HV is 3-cell LiPo compatible and features a Trail profile with a strong drag brake setting to improve control, and Crawl profile with hill hold and instant reverse for extremely technical courses. Both help you navigate any trail with ease.
Torque rules the trail! The 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.
Digital precision, waterproof construction, and high-strength metal gears with a ball-bearing output give TRX-4 the durability and steering authority to reliably power through tough challenges.
The Traxxas TQi radio system features exclusive 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 match your pace. The grip-mounted rocker switch selects high or low range gears to suit the terrain while a separate toggle switch engages or disengages the locking differentials, all on the fly. Best of all, the TQi is compatible with the #6511 Wireless Module so you can set up everything right from your smartphone.
Three fully-waterproof micro servos actuate the front and rear differentials as well as the transmission’s high/low range selection. Sleeved micro cables eliminate complicated linkages that would otherwise limit suspension articulation.

The Pro Scale LED system takes full advantage of the Bronco’s highly-detailed headlights and tail lights with working turn signals, reverse lights, high and low beams, and more. Learn more.
The 2021 Bronco brings replica realism to new heights. Rugged fender flares accentuate the Bronco’s muscular styling. The grille is deeply molded and equipped unique LED-ready lenses. The heavy-duty, winch-ready bumper is outfitted with a metallic fairlead. Authentic details abound, all the way to the functional spare tire.
Ford Bronco rolls out on 1.9” replicas of the gloss-black alloy wheels that outfit the premium Wildtrak Bronco. The bold six-spoke design is accented with beadlock detailing and six simulated lugs and, and proven Canyon Trail tires wrap the rims.
Tough inner fenders mount directly to the frame and shock towers to provide substantial look and feel to the TRX-4. The authentic realism adds to the fun while also helping to keep rocks, mud, and twigs out of the chassis.
Functional rock sliders help prevent damage and provide extra support for the body. The additional bracing adjusts for different widths.
Tough and functional, the Bronco’s rugged replica bumper features an aggressive, modular design complete with tow hooks, metallic-finish fairlead, and replica winch.
Precision molded features give the Bronco display-worthy detail and unbeatable realism. Authentic “Trail Sights,” wide fender flares and rugged replica bumpers are all included. There’s even a fully-functional spare tire.
To achieve total realism, the Bronco’s unique windshield cowl with integrated side mirrors and wiper blades are recreated as injection-molded parts. No effort was spared to deliver the most authentically-detailed and accurate model possible.
You won’t get a flat out on the trail in the TRX-4 Bronco, but it’s nice to know you’ve got a fully-functional spare riding on the back.
