Ultimate Durability
How do you improve the toughest truck ever to wear the Traxxas name? You add aluminum—lots of aluminum! X-Maxx Ultimate 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.
Included Wireless Module
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.
Belted Tires
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.
Maximum Steering Authority
With a staggering 650 oz-in of torque and full steel gears, the High Torque Maxx Servo gives X-Maxx Ultimate complete steering authority on even the largest Sledgehammer® tires. The case features an anodized aluminum center section with cooling fins and ball bearings for increased precision.
