Traxxas XRT 8S Brushless Electric X-Truck (Orange) 78086-4

The Traxxas XRT™ fuses race-inspired design and engineering with X-Maxx® power and strength. The result is an all-new platform with sharp reflexes and unprecedented stability that is capable of exploiting the upper range of extreme 8s power and speed.

BUILT FOR SPEED AND HANDLING

XRT was 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™ race tires are a revolutionary new hybrid design with densely packed biting edges and sipes. They deliver outstanding grip on hard-packed surfaces along with fast and quiet-running precision.

VXL-8S POWER SYSTEM

Already Traxxas’ most powerful speed control, XRT’s VXL-8s™ goes even further with 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.
