XRT 8S Ultimate Ready to Run (GreenX) (TRA78097-4-GRNX)

The Traxxas XRT Ultimate redefines large-scale performance by blending the raw power and durability of the X-Maxx platform with precise race-truck handling. Loaded with over $1,000 worth of premium upgrades, the 2025 edition takes it even further with enhanced graphics, stronger axles, and the most powerful steering servo ever offered in an XRT model. From the track to the trail, this is the ultimate expression of X-Truck engineering.

Built for uncompromising durability, the XRT Ultimate is outfitted with high-strength aluminum components across the suspension, chassis, drivetrain, and steering. These upgrades not only deliver superior toughness but also improve stability and precision at high speeds. Machined aluminum differential housings, steering blocks, motor mounts, and hub carriers ensure that every component is battle-ready for extreme performance.

Handling is elevated by belted Gravix tires featuring a directional tread and lightweight internal belting for exceptional grip, reduced road noise, and consistent shape under load. Combined with adjustable TUBES toe links and precision-machined bellcrank steering, the XRT Ultimate delivers confident control on any surface.

At the heart of its commanding steering is the High Torque Maxx Servo, delivering an incredible 650 oz-in of torque through steel gears and an aluminum center case. This high-output servo ensures authoritative steering response even under the demands of high-speed, off-road driving.

Performance is driven by the VXL-8s brushless power system, capable of propelling the truck past 60 mph with 8s LiPo power. Hardened steel pinion and spur gears, heavy-duty driveshafts, and an aluminum transmission cover keep everything in perfect alignment under extreme conditions. The aluminum GTX shocks with TiN-coated shafts and oversized oil volume handle the roughest terrain with ease and stability.

With the included TQi 2.4 GHz radio system and factory-installed Traxxas Link Wireless Module, drivers can access a wide range of tuning options and real-time telemetry through the free Traxxas Link app. View live data such as speed, RPM, temperature, and battery voltage from a customizable dashboard right on a mobile device.

The XRT Ultimate stands out visually as well, thanks to its exclusive ProGraphix body with reinforced structure and rigid internal frame for added protection. Anodized aluminum accents on parts like the wheelie bar wheels and transmission cover provide a high-performance aesthetic that matches the truck’s bold capabilities.

Factory-assembled and Ready-To-Race, the Traxxas XRT Ultimate includes the TQi radio system, VXL-8s electronic speed control, and high-quality maintenance tools. To complete the setup, users will need two 4-cell 6700 mAh LiPo batteries, a 4s LiPo charger, and four AA batteries for the transmitter.
