Product Video



Traxxas uses technology and innovation to deliver a fun and exciting RC experience with more power, speed, and convenience than you ever thought possible.


Hoss 4X4 VXL uses Traxxas’ patented Self-Righting feature to keep the fun going, even when you get carried away with the wheelies or land upside down. Simply press a button on the TQi™ transmitter and, in most circumstances,* Hoss 4X4 VXL will be back on its wheels in just seconds and ready for more action! *3s LiPo battery required.


The Hoss 4X4 VXL’s rugged and innovative clipless body latching system delivers secure mounting and easy one-handed removal. Battery changes are fast and there are no body clips to keep up with. The internal body cage with integrated roof skid and tailgate protector strengthen the body for extra-long life.


A tough internal cage structure supports the body, and outer reinforcements enhance the aggressive look. Roof and tailgate skids protect against wear-through from skidding, while reinforcements at the mounts prevent tear-through.


Traxxas gives you the freedom to drive the Hoss on your terms, regardless of the weather. Thanks to Traxxas’ patented innovative waterproofing solutions, water, mud, and snow won’t slow down the Hoss 4X4. Drive where you want, when you want—the only limit is your imagination.


A wheelie bar is mandatory equipment to handle the Hoss’ wheel-standing torque. Ride practically never-ending wheelies on pavement and keep the wheels-up action under control under hard acceleration. The integrated wheelie bar has the perfect amount of flex to absorb impacts on less-than-perfect landings. It also features a convenient handle to transport your Hoss to the next adventure.


The fully featured Traxxas TQi™ 2.4GHz radio system delivers superior speed, precision, and control. It is Traxxas Link™ enabled so you can add the Traxxas Link Wireless Module (part #6511, sold separately) and connect wirelessly to the Traxxas Link app using your smart phone. The Traxxas Link app allows you to adjust your settings and view real-time telemetry with optional accessories.


The Torque-Biasing Center Drive absorbs shocks to improve driveline durability. The center drive also distributes power to all four wheels for mind-bending four-wheel drive acceleration without the side effects of a typical center differential. Center differentials allow tires in the air to balloon uncontrollably, while the Torque-Biasing Center Drive allows wheelies off the line with seamless power distributed to all four wheels.


Hoss 4X4 VXL’s massive Velineon 540XL brushless motor is 25% longer than the standard 3500kV Velineon brushless motor for nearly limitless wheel-standing torque at your command. The waterproof VXL-3s speed control delivers up to 11.1-volts of LiPo power through oversized 6.5 mm connectors. The ESC is fan-cooled and packed with innovative convenience and safety features, making the VXL-3s just as powerful as it is easy to use.


TSM works behind the scenes to help harness Hoss 4X4 VXL’s extreme brushless power for maximum acceleration and ultra-precise control. Adjust the amount of assistance from off to 100% right from your transmitter.


Hoss rides tall on large 5.3” Sledgehammer tires for that classic monster truck profile. With nearly 3 inches of center ground clearance, Hoss goes places other trucks can’t. The long 11.62” (295 mm) wheelbase increases high-speed stability. Short front and rear overhangs place bulk of Hoss’ weight between the wheels for sharp turn-in response and improved handling.

Sealed Ball Bearings

Hex hardware with Rust-Resistant Black Oxide Coating

Reinforced Front and Rear Bumpers

Tough reinforced bumpers protect the chassis against impacts. The specially designed front bumper provides a high approach angle that allows the Hoss to climb up and over obstacles with ease. The rear bumper mounts a perfectly positioned wheelie bar to help prevent the Hoss 4X4 VXL from back-flipping under its explosive power.

New ProGraphix Body

Hoss 4X4’s aggressive monster truck ProGraphix™ body comes trimmed and pre-painted with the decals already applied. Tough internal reinforcements maintain the body’s integrity while roof skids provide rollover protection to keep the body looking fresh.

Sledgehammer Tires and 2.8” Black Chrome Wheels

Large 5.3” Sledgehammer tires combine excellent ground clearance with true mud-slinging fun. The open-block tread design claws into gravel, dirt, and grass for sure-footed 4X4 traction on nearly any surface. The heavy-duty rubber compound is specially formulated to resist tearing and bonds exceptionally well to the aggressive black chrome wheels.

Secure Body Latch

Hoss’ clipless ProGraphix® body mounts on specially designed shock towers. The easy-to-use latch unlocks instantly with the quick swipe of a thumb and locks again with a noticeable detent to let you know it’s securely fastened.

Modular Chassis

The Hoss 4X4’s modular design creates a chassis that’s both strong and easy to maintain. The front and rear bulkheads remove easily with just a few screws. In less than a minute using a power screwdriver, you’ll have full access for easy service and adjustment

Heavy-Duty Composite Arms

Molded from our toughest composite material, Hoss’ heavy-duty suspension arms provide just the right amount of flex to resist breaking—even in cold weather! From skate parks to 10-foot ramps, these heavy-duty arms stand up to even the most punishing drivers for non-stop fun behind the wheel.

Ultra Shocks

Oil-filled Ultra Shocks utilize dual X-ring technology for a perfect seal and silky-smooth performance. The large oil capacity and rugged design soaks up big jumps and off-road abuse for smooth driving performance. They are easy to tune with a wide range of available oils, springs, and pistons.

5-Channel Receiver with Failsafe

The TQi 2.4GHz receiver stores up to thirty Traxxas Link™ enabled transmitters in memory. Integrated telemetry ports allow real-time data to transmit from your Traxxas model to the TQi transmitter. In the event of signal loss, the receiver automatically returns the throttle to neutral and holds the last steering position.

Waterproof Receiver Box

The Hoss incorporates a waterproof receiver box in the nose of the chassis to save weight and provide a clean, high-tech appearance. The antenna and servo wires route neatly through a patented watertight seal to protect the receiver from water. No matter what the weather, Hoss 4X4 VXL is ready for action!

Optimum-Geometry Steering with Integrated Servo Saver

A dual-bellcrank design pivots on rubber-sealed ball bearings for smooth action in the harshest conditions. The integrated cam-type servo saver protects the servo gears from crash impacts without sacrificing steering precision.

Digital High-Torque Waterproof Steering Servo

The Hoss’ extreme speed and tall Sledgehammer tires require a steering servo that’s both strong and durable. The waterproof 2075 digital high servo provides robust steering authority with ball bearings for precise control and quick reflexes.

VXL-3s ESC with Fan

The waterproof Velineon VXL-3s speed control is packed with technology to deliver maximum power. Large heat sink, integrated on/off switch, and three programmable drive profiles top the feature list. Two-stage low voltage detection allows full LiPo compatibility, including powerful 11.1-volt 3S packs!

Innovative Battery Hold-Down

A rugged battery hold-down secures the battery safely in the chassis without flimsy straps or clips to lose. A beefed up latch provides solid locking action to keep batteries safe no matter how wild the action gets.

Chassis Nerf Bars

Rugged side nerf bars protect the chassis from rocks and other impacts. Special channels in the nerf bars support the sides of the body for a tighter, more secure fit.

Velineon 540XL Motor

A sensorless Velineon 540XL 2400 kV motor delivers extreme performance with nearly zero maintenance. Ultra high-temperature Neodymium magnets, high-speed bearings, and a precision, 4-pole balanced rotor deliver smooth running and long life.

Fixed Gear Adapter

Fixed gear adapters take the guesswork out of setting your gear mesh. The fixed positioning keeps the gear mesh tight, even after the harshest landings. The innovative motor mount keeps the 540XL motor locked firmly in place with just a single screw for easy maintenance.

Heavy-Duty 4mm Turnbuckles

Hoss 4X4 uses the same heavy-duty steel 4mm turnbuckles developed for the Slash 4X4. Broad flat sections make toe and camber adjustments easy with the included wrench. The fully captured rod ends take a beating and won’t pop apart during rigorous off-road pounding.

Extreme Heavy-Duty Driveshafts

The Hoss’ extreme heavy-duty driveshafts are modeled after the legendary Slash 4X4, but are beefed up in critical areas for even more outrageous power handling. The larger diameter half shafts offer the same articulation and suspension travel, but are rated for even more tire-shredding torque.

Steel-Gear Differentials

Heavy-duty front and rear oil-filled differentials utilize steel-gear internals for maximum durability. Silicone gaskets and X-ring seals allow you to tune the amount of locking action by varying the viscosity of the fluid inside the differentials.

Extruded Aluminum Driveshaft

A one-piece extruded aluminum driveshaft is both strong and lightweight. Internal splines fit directly onto the input shafts of the front and rear drive assemblies. Altogether, this shaft runs straight and true for ultra-smooth driveline operation.

Heavy-Duty Steel Spur Gear

Designed from the start to handle big brushless horsepower, Hoss 4X4 VXL’s driveline uses a rugged steel spur gear with large 0.8 module/32-pitch teeth for reliability no matter how much power you pour on.

Rubber-Sealed Ball Bearings

Maximizing speed requires as little friction as possible. Hoss 4X4 rides on precision rubber-sealed bearings for super low-friction performance and maximum protection in dusty environments. They are used throughout the truck and are virtually maintenance free.
