Race-Inspired Engineering
The Traxxas XRT® ®
BUILT FOR SPEED AND HANDLING
XRT is engineered with a focus on speed, handling, and performance. XRT’s low center of gravity, ultra-wide stance and low-profile body deliver confidence and control as XRT accelerates across the wide-open spaces to an all-out speed of 60+ mph.
PROVEN TOUGH ALL-METAL DRIVELINE
XRT performance and durability begins with its all-metal 8S driveline. Steel 4-gear differentials and steel driveshafts are joined by a high-strength extruded aluminum center shaft. It’s a precision-engineered recipe that has been proven monster-truck tough in the X-Maxx.
RACE-INSPIRED LOW-CG CHASSIS
XRT’s performance-focused chassis design is configured to lower the center of gravity for superior handling and stability. The dual 6700 4S batteries and the steering servo are positioned to place the weight as low as possible in the chassis and provide protection for these critical components.
PATENT-PENDING CLIPLESS BODY
XRT’s patent-pending clipless body easily removes and installs in just seconds and yet it locks in place with incredible strength and security. The system uses a cage inside the body to minimize flex while external skids are strategically placed to protect the body.
GRAVIX RACE TIRES
XRT’s Gravix®
VXL-8S POWER SYSTEM
XRT’s VXL-8s™ speed control uses an aggressive tune that maximizes power output across the entire RPM range. More power under the curve delivers mid-range punch that hits hard for rolling wheelies on demand. Bury the throttle at any speed and XRT responds instantly with effortless acceleration.
X-Truck Companions
Each X-Truck offers its own unique driving experience. X-Maxx reigns as the king of monster trucks with its big tires, big ground clearance, and big attitude. XRT is the companion to X-Maxx, engineered for a race-inspired driving experience with its sharp handling and unmatched speed.
Precision Engineering
Traxxas engineers spent countless hours designing every joint, angle, and touch point for maximum strength and convenience. The race-inspired triangulated structure transfers and dissipates impact energy through the chassis to minimize the possibility bending or breaking a support.
High-Strength Axle Carriers
High-strength front and rear axle carriers are stronger than ever with more material for improved strength. They house huge sealed ball bearings for reduced friction and added durability.
WideMaxx Suspension
Race trucks are built low and wide for maximum stability. XRT’s WideMaxx®
The Ultimate 8s Power System
XRT’s VXL-8s™ goes farther with a new aggressive tune that maximizes power output across the entire RPM range. The additional mid-range punch hits hard for rolling wheelies on demand. The Velineon®
All Metal Driveline
X-Maxx pioneered 8S toughness with an engineered all-metal driveline. XRT uses the same Traxxas-Tough™ driveline with sealed 4-gear differentials and extreme-duty diff covers to increase bearing support and eliminate flex.
Race-Inspired Handling
Low center of gravity, race-tuned aluminum shocks and an ultra-wide stance give XRT razor-sharp reflexes and flat cornering response that feels track ready. Off the track XRT is equally at home ripping full-throttle 8s powerslides with massive roost and a never-lift attitude.
Integrated Cold-Air Intakes
Innovative cold air intakes direct cooling air over the motor and speed control for increased efficiency and run time. The hood mounted intake integrates with the shock tower to deliver air to the VXL-8s™ Speed control. The roof vent channels cooling air directly to the dual motor fans.
Waterproof Electronics
There’s a difference between waterproof and water-resistant. XRT continues the Traxxas legacy of giving you patented, best-in-class waterproofing solutions and the freedom to drive where you want, regardless of the elements.
Patent-Pending Clipless Body
XRT wears the toughest clipless body yet with a full internal frame and wide attachment points that virtually eliminate tear-through damage. A thick roof skid plate forms an integral part of the frame with front and rear buttressing for superior rigidity.
Smooth Chassis Design
XRT’s interlocking skid plates integrate precisely with the chassis to create a smooth under tray to absorb ground impacts uniformly for predictable, snag-free performance.
Secure Battery Storage
XRT protects your battery investment by positioning the batteries deep in the chassis with full side protection for battery packs. Rugged snap-lock battery retainers keep a firm grip on the batteries no matter how intense the action gets.
Traxxas Stability Management
Traxxas Stability Management®
Details
High-Downforce Wing
XRT’s rear wing provides added stability for 60+ mph speed runs and integrates neatly with the clipless body for a sophisticated look. The wing mount soaks up even the hardest landings without transferring shock energy to the chassis.
XRT Race Wheels
XRT’s large 3.8" race wheels feature a matte black finish for a high-tech look. A huge 24 mm splined hub maximizes surface area with 17 mm aluminum lock nuts to secure them in place.
Integrated Wheelie Bar
XRT’s wheelie bar helps prevent backflips under full-throttle acceleration and flexes to absorb impacts on less-than-perfect landings. The integrated wheelie bar also functions as a convenient handle to transport XRT to your next adventure.
Rugged Top Skids
XRT’s rugged top skids protect the clipless body from damage. Internal reinforcements maintain the body’s integrity.
Gravix Race Tires
XRT’s revolutionary Gravix®
Integrated Cold-Air Intakes
Cold-air intakes are fully integrated into XRT’s clipless body frame for maximum strength and tear prevention. The lower intake even features an internal grille to keep rocks and other debris out of the chassis and away from the steering components.
GTX Race Shocks
GTX™ aluminum race shocks are built for ultra-smooth, long-lasting performance. The heavy-duty springs and shock bodies are tuned for high-performance handling that complements XRT’s low and lean stance.
Integrated Shock Tower Design
XRT’s shock towers are an integral part of the frame with massive buttresses to dissipate shock loads throughout the chassis. Heavy-duty receivers secure the clipless body latches directly to the towers for maximum strength.
Modular Chassis
XRT’s chassis relies on modules that key into each other at precise angles to add strength and support where it’s needed most. This high-strength design also makes maintenance a breeze.
Aluminum Heatsink with Dual Fans
XRT’s aluminum heatsink wraps around nearly 75% of the motor’s exposed surface to pull out more heat. Dual electric fan shrouds draw cooling air from the body vents through the oversized fins for more effective cooling performance and longer run times.
Rock Solid Motor Mount
A rock-solid motor mount cradles the motor and locks it in place so it can’t flex or slip out of position. Four keyed pins set the gear mesh, eliminating the need for complicated adjustments.
Snap-Lock Battery Retainers
Hook and loop battery hold down straps are messy, frustrating, and steal time away from your driving fun. Traxxas engineering solves this with our proven snap-lock solution that securely holds and protects batteries. You can even insert body clips for maximum battery security.
