Traxxas 78097-4 Blue XRT® Ultimate Race Truck
XRT® revolutionized the 8s experience by combining X-Maxx strength with race truck handling. XRT Ultimate takes it over the top with a full complement of high-strength aluminum upgrades in key performance areas. Outfitted with all-new belted Gravix™ tires, no other truck combines XRT Ultimate’s brutal 8s power and handling precision in a package this fun. Quantities of this very special XRT are extremely limited.
XRT receives substantial aluminum upgrades in all key areas of performance: suspension, chassis, drivetrain, and steering to usher in a new era of X-Truck™ strength and durability. XRT’s aluminum upgrades improve high-speed stability and precision while creating the toughest truck ever to wear the Traxxas name.
A Traxxas Link™ Wireless Module comes standard on XRT 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.
XRT Ultimate’s belted Gravix™ tires deliver game-changing performance on the track or in the wild. The directional tread pattern provides excellent traction and runs quieter than typical off-road tires. Lightweight belting in the carcass maintains the tire's shape for a larger contact patch, more grip, and responsive handling at any speed.
