Optional extras are never added for you: Upgrades for the X-Maxx Ultimate
X-Maxx® is the truck that redefined Traxxas Tough. X-Maxx Ultimate combines that legendary toughness with almost $900 in aluminum upgrades and performance parts for maximum strength and precision. The 2025 X-Maxx Ultimate goes even further with new bold graphics, upgraded axles, and our most powerful steering servo. Don't miss your chance to own the Ultimate monster truck!
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.
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.
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.
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.
