Product Description

This is the Traxxas X-Maxx 4WD 8S Brushless Ready-to-Race Monster Truck with Prographix body.

The new 8S X-Maxx has been beefed up with new diff gears, driveshafts, motor cooling fan, and a wheelie bar to help keep the truck on its tires under extreme acceleration!

X-Maxx is an all-new, clean-sheet design, engineered from the start to take Traxxas Tough to a whole new level. Unrelenting 4X4 power, mammoth size, and ferocious determination makes this mighty monster a truly worthy successor to the Maxx legacy. At nearly 30-inches in length, this truck is a BEAST! The new 8S X-Maxx takes the 30-volts of power and turns the X-Maxx into the ultimate 50+MPH monster truck!

Size Wins

X-Maxx is enormous. Size wins by giving you the advantage to power over and through extreme landscapes. Mammoth 8-inch tall tires, long-arm suspension, and huge ground clearance dwarf the surroundings for virtually unstoppable Monster truck fun.

Extreme Power

Wildly over-powered, X-Maxx stays true to form with its Maxx DNA. 8s 30-volt dual-LiPo muscle and a Velineon 1200XL Big Block motor propel X-Maxx with brutal authority and an exacting quickness that completely defies its enormous size.

Exclusive Self-Righting

Before X-Maxx, monster trucks would sometimes roll over upside down, bringing the action to a screeching halt. Now, press a button and in most cases this exclusive patent-pending Traxxas innovation flips X-Maxx back over onto its wheels so that you can quickly get back to having fun.

Traxxas Stability Management

Traxxas Stability Management (TSM) allows you to experience all the extreme power, speed, and acceleration that was engineered into your Traxxas model by making it much easier to control the vehicle on common slippery surfaces such as loose dirt, smooth concrete, and even ice and snow. It can be dialed from completely off to 100%, and anywhere in between, right from the TQi transmitter!


Insightful engineering and precise integration of innovative solutions set X-Maxx in an all-new category of superior performance. It's as satisfying and rewarding to use as it is fun and exciting to drive.


The full X-Maxx experience of strength, power, and agility relies on all the carefully engineered details that begin to emerge when you peel back the layers. Old conventions were discarded as every system and dimension was examined and taken to a level worthy of the Maxx legacy.
