Key Features
- Portal Axles — The TRX-4 is equipped with Traxxas' game-changing portal axle system, which lifts the truck at the wheels to provide massive centre pumpkin ground clearance equivalent to tyres over an inch taller than standard designs. This engineering breakthrough allows you to straddle boulders and navigate extreme terrain that would stop other crawlers, whilst the portal gear reduction dramatically reduces undesirable torque twist, translating motor torque into straight, powerful forward motion rather than wasting energy twisting your rig sideways.
- Remote Locking Differentials — Traxxas gives you the versatility to lock and unlock the front and rear differentials directly from your transmitter to suit your driving needs. Leave the differentials unlocked for relaxed trail driving with smooth, tight turning and better handling at speed, or lock the front and rear differentials—or just the front—when the trail gets technical for superior grip over extreme terrain. Sleeved micro cables control the differential action whilst maintaining scale appearance without limiting the chassis's huge suspension articulation.
- Hi/Low Range Transmission — A two-speed transmission with remote shifting capability lets you shift into low range from your transmitter for incredible 4-wheel drive pulling torque when tackling steep climbs and technical obstacles, or shift into high range for blasting down the trail at speed. This unmatched versatility makes the TRX-4 adaptable to just about any driving situation or style.
- Fully Waterproof Electronics — Traxxas pioneered fully waterproof RC vehicles years ago with innovative designs, and the TRX-4 Scale and Trail Crawler is genuinely fully waterproof—not merely splash resistant. This patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water damage to your electronics, making it a true all-weather platform.
- Heavy-Duty Steel Frame — A rigid formed-steel ladder frame with moulded cross members creates an extremely tough backbone that lets the suspension do the work it was designed to do. The elimination of chassis flex allows for precise wheel placement when navigating technical terrain, and the 1.5mm thick steel frame rails combined with large diameter steel links and heavy-duty, extra-wide rod ends ensure the suspension remains firmly mounted through the most demanding trails.
- Clipless Body Mounting System — The Bronco introduces a new level of realism and convenience with an integrated quick-release system that secures the body invisibly. Traditional posts and body clips are gone, replaced by a hidden mechanism that holds tight on the trail yet releases in just seconds to access the chassis for maintenance.
- Aluminium GTS Shocks — Oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis, featuring silver-anodised aluminium construction. These deliver silky-smooth damping performance with threaded shock bodies for easy ride height adjustments, plus O-ring cap seals and dual X-ring shaft seals for durability and scale realism.
- XL-5 HV Electronic Speed Control — The speed control brings genuine 3S LiPo capability for stronger, more efficient running with updated profiles designed for smooth and precise control. A Trail profile facilitates smooth driving for most adventures, whilst a Crawl profile introduces hill hold and instant reverse for extremely technical courses. Long run times of up to 2 hours are possible with a Traxxas 3S 5000mAh iD LiPo battery.
- Titan 21T Brushed Motor — A reliable 21-tooth brushed motor delivers strong torque and consistent power for trail driving, paired with the XL-5 HV ESC for smooth, controlled performance across varying terrain and battery configurations.
- TQi 4-Channel Radio System — The Traxxas TQi 2.4 GHz transmitter features cruise control for long-distance treks, allowing you to set your speed and then use the multi-function knob to fine-tune it faster or slower for precise pace matching during hours of driving fun. The system is customisable and puts full control of your crawler directly in your hands.
- Scale Detail and Realism — Injection-moulded door handles, mirrors, and fender flares plus a functional spare tyre deliver incredible realism. The legendary Ford Bronco Ranger XLT body features rugged chrome bumpers with recovery D-rings, an LED-ready grille, and a front bumper designed to be compatible with many popular off-road accessories for customisation and personalisation.
- Metal Gear Digital Servo — A full-metal gear digital servo gives you the durability and steering authority needed to confidently and reliably power through tough situations with precision steering control.
- Canyon Trail 1.9 Tyres — The 1.9 Canyon Trail tyres and tuned foam inserts are super-soft and grippy, delivering 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 tyre combinations for upgrading if desired.
- Traxxas Tough Construction — Built to handle the rigours of remote locations and all-day driving fun, the chassis features hardened steel CV-style half-shaft joints that are ultra reliable, whilst brushless-ready steel portal axle and transfer case gears are smooth and quiet. Traxxas' composite materials have been refined over three decades for ultimate strength and durability.
Technical Performance
The Traxxas TRX-4 2021 Ford Bronco is engineered from the ground up as a serious trail platform that balances scale authenticity with genuine off-road performance. The chassis measures 584mm overall length with a 549mm wheelbase, standing 239mm tall with an impressive 80mm ground clearance thanks to the portal axle system. At 2.91kg fully assembled, it's substantial enough to feel like a quality piece of engineering without being unwieldy. The approach angle of 52°, departure angle of 49°, and breakover angle of 58° demonstrate the vehicle's designed capability for navigating rocks, hills, and technical terrain. The rigid steel frame construction combined with the portal axles ensures minimal flex during suspension articulation, meaning your wheel placement remains precise when picking your line through obstacles. The XL-5 HV electronic speed control is specifically tuned for 3S LiPo compatibility, delivering smooth, efficient power with selectable driving profiles—the Trail mode for relaxed exploration and Crawl mode with hill-hold and instant reverse for technical climbing. The Titan 21T brushed motor provides robust torque delivery, and with a quality 3S 5000mAh LiPo battery you can expect up to 2 hours of continuous running. The two-speed transmission with 32-pitch gears offers genuine low-range torque multiplication for extreme climbs, whilst high range provides highway-style speed. All electronics are fully sealed and waterproof, using Traxxas' patented waterproofing system rather than merely splash-resistant construction, so winter running, muddy trails, and water crossings are all within reach. The combination of oil-filled aluminium shocks, locking differentials, and portal axles creates a vehicle that can adapt from smooth trail cruising to genuine rock-crawling without modification—a versatility unmatched in the 1/10 ready-to-run RC crawler category.

Frequently Asked Questions
- Is the Traxxas TRX-4 Bronco suitable for beginners? — The TRX-4 is rated as Skill Level 3, which indicates it's best suited to intermediate to experienced RC enthusiasts rather than absolute beginners. However, the intuitive controls, excellent handling, and forgiving suspension make it approachable for anyone willing to learn. The two-speed transmission and locking differentials require understanding how to use them effectively for best results. If you're new to RC crawlers, you may benefit from assistance or guidance from experienced RC drivers when learning the vehicle's full capabilities.
- What battery does the TRX-4 Bronco need? — The XL-5 HV speed control supports 2S and 3S LiPo batteries, as well as NiMH stick packs. For maximum performance and runtime, a Traxxas 3S 5000mAh iD LiPo battery is recommended, which can deliver up to 2 hours of continuous running. You'll also need a suitable charger—the EZ-Peak Plus 3S 4Amp is a popular choice for fast charging LiPo batteries. The transmitter requires four AA alkaline batteries.
- How waterproof is the TRX-4 Bronco? — The TRX-4 features fully waterproof electronics using Traxxas' patented waterproofing system. This is genuine waterproofing, not splash resistance, which means you can confidently drive through creeks, mud, snow, and wet conditions without fear of water damage. The sealing design protects the motor, ESC, servo, and receiver from water ingress whilst maintaining the vehicle's performance and reliability.
- What makes the portal axles special on the TRX-4? — Portal axles lift the truck at the wheels to create massive ground clearance equivalent to tyres over an inch taller than conventional designs. This allows the TRX-4 to clear obstacles that would trap other crawlers. Additionally, the portal gear reduction dramatically reduces torque twist—the unwanted rolling motion that occurs when powerful torque is applied through side-mounted axles. The total axle gear reduction is over twice that of non-portal designs, meaning your motor's power is translated into straight forward motion rather than being wasted twisting the chassis.
- Can I upgrade the motor and ESC? — The TRX-4 is described as brushless-ready, meaning it's compatible with brushless motor and ESC upgrades. The chassis can accept brushless upgrades for increased power and efficiency if desired as you progress with the hobby. The steel portal axles, transfer case gears, and drivetrain are all designed to handle brushless power levels.
- How do the locking differentials work? — The front and rear differentials can be locked independently using buttons on your TQi transmitter, allowing you to change differential behaviour whilst driving. Unlocked differentials provide smooth, tight turning for general trail driving at speed. Locking the differentials (or just the front) engages all wheels on that axle to spin at the same speed, distributing power evenly for superior traction on technical, slippery terrain. The system uses sleeved micro cables that maintain scale appearance whilst allowing full suspension articulation.
- What is the two-speed transmission and how does it work? — The TRX-4 features a 2-speed hi-low range transmission controlled by your transmitter. High range provides speed for cruising and open terrain, whilst low range multiplies torque for climbing steep hills and negotiating extreme technical obstacles. You can shift between ranges on the fly, adapting to changing terrain without stopping. This gives the TRX-4 genuine 4-wheel drive versatility from a single motor.
- What is the difference between the TRX-4 Bronco and other Traxxas crawlers? — The TRX-4 Bronco combines the proven TRX-4 platform with iconic 2021 Ford Bronco styling. The chassis architecture—including portal axles, locking differentials, two-speed transmission, and waterproof electronics—is shared with other TRX-4 variants, but each model features unique body styling and scale details. The Bronco variant offers exceptional display-quality detail with injection-moulded components, functional spare tyre, LED-ready grille, and scale bumpers with recovery D-rings. If you prefer a different vehicle design, Traxxas offers the TRX-4 with other popular bodies, but the Bronco is particularly valued for its authentic appearance and nostalgic appeal.
