XRT Ultimate
Ultimate Durability

Ultimate Durability

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.

Included Wireless Module

Included Wireless Module

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.

Belted Tires

Belted Tires

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.
