X-Maxx Size Comparison

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.

X-Maxx Power

Extreme Power

At Traxxas, too much power is never enough! The durability of the VXL-8s is matched only by the sheer ferocity of its 8s 30+ volt dual 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.

X-Maxx Drivetrain

Maxx-Duty Drivetrain

X-Maxx puts the power to the ground through tough all-steel drivetrain gears, the revolutionary Cush Drive system, and our strongest driveshafts ever. The Torque-Biasing Center Drive improves driveline durability and drives larger module ring and pinion gears on the toughest differentials we have ever produced.
