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
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
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.
Maximum Steering Authority
With a staggering 650 ounce-inches of torque and full steel gears, the High Torque Maxx Servo gives XRT Ultimate complete steering authority, even with wide Gravix tires. The case features an anodized aluminum center section with cooling fins and ball bearings for increased precision.
Features
TQi Transmitter with Wireless Module
With 60+ mph of 8s power on tap, XRT Ultimate needs maximum precision and control. XRT Ultimate's factory-installed Wireless Module adds powerful TQi tuning and telemetry tools on your mobile device. Use the free Traxxas Link; app to control steering and throttle sensitivity; steering percentage; braking strength; and throttle trim by simply touching and dragging the sliders on the high-definition graphic interface.
Aluminum GTX Shocks
XRT Ultimate adds ultra-smooth TiN-coated shafts, color-matched aluminum shock caps, and threaded adjustment rings to its proven GTX shocks. GTX shocks soak up massive bumps to smooth out the roughest terrain. Their large oil volume dissipates heat for all-day shredding while an integrated wiper seal keeps the shafts clean.
Aluminum Differential Housings
Front and rear machined aluminum housings eliminate flex to keep XRT's huge differentials in perfect alignment jump after bone-crushing jump. The housings are milled from high-grade 6061-T6 aluminum for maximum strength and protected by a brilliant anodized finish.
Aluminum Caster and Steering Blocks
XRT Ultimate's caster and steering blocks combine the brute strength of 6061-T6 aluminum with carefully engineered steering and suspension geometry. The brilliant anodized finish adds high-tech style with laser-etched logos to show off your genuine Traxxas performance parts.
TUBES Toe Links
Adjustable TUBES toe links make it easy to dial-in the perfect settings for greater precision and control. TUBES are lighter than steel and stronger than titanium with a unique hollow tube design which maximizes rigidity while reducing weight. Made from ultra-high-grade 7075-T6 aluminum, TUBES feature a brilliant, anodized finish for extra style.
Precision Steering
Machined from tough 6061-T6 aluminum, XRT Ultimate's ultra-rigid bellcrank assembly drastically enhances steering precision and strength. Tight tolerances and a special servo saver bushing allow the bellcranks to pivot smoothly on sealed ball bearings with a heavy-duty servo saver spring for added protection.
High-Torque Metal Gear Servo
XRT Ultimate features Traxxas' most powerful servo to turn its wide Gravix tires with maximum authority. With 650 oz-in of torque on tap and large metal gears, the 2085RL steering servo has extra power on tap for extreme driving on any surface. An aluminum double-shear servo horn eliminates flex for fast, responsive steering at high speeds.
Aluminum Motor Mounts
High-strength aluminum motor mounts and washers lock the massive 1200XL Big Block firmly into place to keep the gears perfectly aligned even on the biggest jumps. The mounts utilize the standard truck's keyed gear mesh system for easy and precise adjustments.
Machined Pinion and Spur Gears
XRT Ultimate features pinion and spur gears machined from hardened steel for maximum power handling and durability.
Aluminum Transmission Cover
The aluminum transmission cover is color-matched to the truck with a laser-etched logo for extra style. Carefully milled from 6061-T6 aluminum, the cover locks into the chassis tightly to keep the transmission gears in perfect alignment. It also works perfectly with the 7866 high-speed overdrive gear set for extreme speed runs.
Ultra-Heavy-Duty Driveshafts
Developed for the two-wheel-drive Sand Car, these driveshafts are the toughest ever fitted to a Traxxas vehicle. New beefed-up differential output yokes are the largest in the X-Truck lineup. Power feeds to 17 mm splined aluminum axles through steel CV driveshafts to maximize suspension travel and durability.
Aluminum Hub Carriers
6061-T6 aluminum stub axle carriers add both strength and beauty to XRT Ultimate without compromising its carefully tuned suspension geometry.
Aluminum Wheelie Bar Wheels
Aluminum wheelie bar wheels add brilliant eye-catching style to the already outrageous XRT Ultimate. Outfitted with aluminum axles and sealed ball-bearings, the wheels feature durable soft-compound tires to help harness XRT’s brutal horsepower.
