1/10 TRX-4 2021 Ford Bronco, 4WD, RTD (Requires battery & charger): Silver

Chassis Details

Heavy-Duty Steel Frame Rails
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.

Metal Servo Horn
A heavy-duty metal servo horn comes standard on the TRX-4 Bronco.

Molded 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 Battery Tray
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.

Floor Pans
Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of the chassis.

Aluminum Scale Shocks
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.

Heavy-Duty Steel Links
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.

Precision Hex Hardware
The TRX-4 uses tough hex hardware throughout for improved strength and easy servicing.

Driveline Details

Portal Axles
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.

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 Differentials
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.

High/Low Transmission
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
A twin friction plate slipper clutch provides some additional protection from motor stalls in extreme crawling conditions.

Sealed Ball Bearings
Black sealed ball bearings resist mud and dirt to keep your rig rolling smoothly.

Geometry Details

Raised Center Driveshafts 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-centering your truck and reduce overall grinding wear.

High Steering and Drag Links
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.

45-Degree Steering Angle
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.

Extreme Approach Angles
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.

High Ground Clearance
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.

Front Motor Design
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.

Electronics Details

XL-5 HV Speed Control
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.

Titan 21T 550 Motor
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.

Metal-Gear High-Torque Waterproof Steering Servo
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.

TQi 4-Channel Radio System
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.

Waterproof Micro Servos with Sleeved Cables
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.

Available Pro Scale' Lighting (ComingSoon)
Elevate your 2021 Bronco to the next level of lighting performance with the Traxxas Pro Scale Advanced Lighting Control System (sold separately). 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.
