X-Maxx Ultimate

Total Performance


How do you improve the toughest truck ever to wear the Traxxas name? You add aluminum—lots of aluminum! X-Maxx receives substantial aluminum upgrades in all key areas of performance: suspension, chassis, drivetrain, and steering to usher in a new era of strength and durability.

Ultimate Durability


A Traxxas Link Wireless Module comes standard on X-Maxx Ultimate to take full advantage of its on-board telemetry. The free Traxxas Link app allows you to make micro-adjustments to the transmitter and view real-time telemetry data like speed, RPM, and battery voltage on your mobile device.

Included Wireless Module


X-Maxx Ultimate’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.


TQi Transmitter with Wireless Module
