Unrelenting 4X4 power, mammoth size, and award-winning innovation make X-Maxx the ultimate monster truck. With 30+ volts of extreme 8s power, X-Maxx defies physics, unleashing jaw-dropping acceleration and 50+ mph speed. Belted Sledgehammer® tires conquer the most extreme terrain while providing unrivaled high-speed stability. Built to take brutal punishment in stride, X-Maxx is the definition of Traxxas Tough(TM).
 
Size Wins
At the end of the day, size always wins. X-Maxx plows over obstacles and muscles through extreme terrain that leaves lesser trucks stranded. Mammoth 8-inch-tall tires, long-arm suspension, and huge ground clearance dwarf the surroundings for virtually unstoppable monster truck fun.
 
Extreme Power
At Traxxas, too much power is never enough! The durability of the VXL-8s&trade is matched only by the sheer ferocity of its 8s 30+ volt LiPo muscle. The speed-tuned 1200XL Big Block motor propels X-Maxx with brutal authority and exacting quickness that warps your senses. No matter what you have driven in the past, nothing will prepare you for X-Maxx.
 
All-Metal Drivetrain
X-Maxx puts its massive power to the ground through an all-metal 8s driveline backed by the revolutionary Cush Drive® system, high-strength extruded aluminum center shaft, and our strongest steel driveshafts ever. The Torque-Biasing Center Drive improves driveline durability and drives huge steel 4-gear differentials.
 
Belted Tires
X-Maxx’s belted Sledgehammer tires deliver game-changing stability and control whether you’re slinging mud or setting speed records. The wide, open-block tread design won’t clog up with dirt or debris and the lightweight belting maintains the tire’s shape for a larger contact patch, more grip, and responsive handling at any speed.
 
Traxxas-Tough Engineering
Trazzas-Tough engineering makes X-Maxx the world's strongest, hardest charging, Ready-To-Drive monster truck. The modular design makes maintenance a breeze and adds strength where it's needed most. X-Maxx gets you off the workbench and out having fun because that's what it's all about.
 
Superior Driveline Protection
X-Maxx's rugged and direct driveline reduces rotational mass and delivers superior durability. The driveline lies completely shielded inside the chassis for worry-free running, safe from rocks and other debris.
 
Self-Righting
Pioneered by X-Maxx, this revolutionary Traxxas innovation flips X-Maxx back onto its wheels after a roll over. In most situations, the fun does not have to stop just to rescue an upside-down truck.
