The Traxxas X-Maxx is the biggest Traxxas truck Traxxas currently makes, and it can run at 50+ mph in stock form. It is built for huge size, serious 4×4 power, and rough terrain rather than just top speed alone.
Quick answer: the biggest Traxxas truck is the X-Maxx
The X-Maxx stands out because it combines monster-truck scale with a strong brushless setup. If you want a big Traxxas truck that still moves fast, this is the model to look at first. For readers comparing speed-focused rigs, the The 8 Fastest RC Trucks You Can Buy Today roundup is a useful place to compare it with smaller, faster options.
| Traxxas X-Maxx feature | What the source lists |
|---|---|
| Length | About 20 inches |
| Height | About 14 inches |
| Width | About 19 inches |
| Weight | About 19 lb |
| Top speed | 50+ mph |
| Power | 8S, 30+ volts |
How fast is the X-Maxx really?
In stock form, the X-Maxx is already quick enough to feel wild for a truck this large. Its 50+ mph top speed is impressive because of how much truck it has to move. That extra mass makes it feel different from lighter Traxxas models like the Traxxas Slash Top Speed: How Fast Is It? and the Traxxas Rustler Top Speed: How Fast Does It Go?, both of which are built around a smaller, lighter platform.
For most hobbyists, that means the X-Maxx is more about huge torque, strong acceleration, and control on rough ground than chasing pure speed numbers. Bigger tires, heavier weight, and aggressive suspension all change how fast the truck feels when you drive it.
What affects RC truck speed?
Speed is not just about the motor. Battery choice, gearing, tire size, weight, surface grip, and drivetrain losses all matter. A truck can have a strong motor and still feel slower if the gearing is conservative or the tires are too large for the setup.
- Battery power: Higher-voltage packs can increase wheel speed when the truck is designed for them.
- Gearing: Taller gearing can raise top speed, but it also increases heat.
- Weight: Bigger trucks usually need more power to feel quick.
- Tires: Large, tall tires can help off-road performance but can also affect acceleration.
- Surface: Grass, dirt, mud, and loose gravel slow a truck down compared with pavement.
Why the X-Maxx is so big
The X-Maxx is Traxxas’ monster truck flagship because it is designed to be huge, tough, and easy to work on. The modular chassis design helps keep the motor and gear drive together as a unit, which reduces chassis flex and makes maintenance easier.
Features that make the X-Maxx stand out
- VXL-8s speed control with advanced microprocessor control
- 1200XL Big Block motor
- Cush Drive system for shock absorption
- All-steel drivetrain gears
- Torque-biasing center drive
- Integrated wheelie bar
- TQi 2.4GHz radio system
- Traxxas Stability Management (TSM)
- GTX aluminum oil-filled shocks
- Waterproof components for mud, snow, and wet ground
Fast models and setups worth comparing
If your main goal is speed, it helps to compare the X-Maxx with other Traxxas trucks and with battery and gearing upgrades. A smaller truck like the Slash or Rustler may feel quicker in some situations because it weighs less and has a different chassis layout.

The X-Maxx is still one of the most exciting Traxxas trucks because it balances speed with size and durability. If you want a huge monster truck that can take abuse and still move at a strong pace, it is hard to beat.
How to go faster safely
If you want more speed from an RC truck, start with the basics and avoid jumping straight to extreme changes. A safe setup is usually better than a fast setup that overheats or breaks parts every run.
- Use the battery type the truck is designed to handle.
- Check motor and ESC temperatures after longer runs.
- Make small gearing changes instead of making a huge jump.
- Inspect tires, driveshafts, and differentials after hard bashing.
- Run on clean, open ground before trying speed upgrades.
That advice matters even more on a big truck like the X-Maxx, because extra weight and big tires put more stress on the drivetrain.
Is the Traxxas X-Maxx good for beginners?
Not usually. The X-Maxx is better suited to experienced hobbyists who can handle its size, power, and maintenance needs. It is durable, but it is still a large, powerful RC truck that can be a lot to manage if you are new to the hobby.
If you are just getting started, a smaller truck is often easier to learn on. Once you are comfortable with control, battery care, and basic maintenance, moving up to the X-Maxx makes a lot more sense.
Bottom line
The biggest Traxxas truck is the X-Maxx. It is massive, runs on 8S power, and can reach 50+ mph while still being built for rough terrain, heavy bashing, and serious durability.
If you want a truck that feels bigger than almost anything else in the Traxxas lineup, the X-Maxx is the clear answer.
