About this part

Race Inspired Big Scale Monster Truck - 8S Capable!

The Traxxas XRT stands out as a remarkable monster truck, combining race-inspired design and engineering with the raw power and strength characteristic of the X-Maxx platform. Its low center of gravity, wide stance, and streamlined body contribute to unparalleled stability and control, enabling the XRT to reach impressive speeds of 60+MPH. The emphasis on speed and handling is evident in its performance-focused chassis design, carefully configured to lower the center of gravity for superior stability. The chassis also accommodates dual 6700 4S batteries (sold separately) and a steering servo strategically positioned to keep the weight as low as possible, enhancing overall performance.

About the XRT 8S

Design

Durability is a cornerstone of the XRT's design, featuring an all-metal 8s driveline that includes steel 4-gear differentials, steel driveshafts, and a high-strength extruded aluminum center shaft. This proven monster-truck tough drivetrain has its roots in the reliable X-Maxx platform, ensuring the XRT can withstand the rigors of extreme bashing. The inclusion of Gravix race tires further contributes to its durability, featuring a revolutionary hybrid design with densely packed biting edges and sipes for exceptional grip on hard-packed surfaces.

Electronics

What sets the XRT apart is its VXL-8S power system, already Traxxas' most potent speed control. The aggressive tune maximizes power output across the entire RPM range, delivering mid-range punch that results in rolling wheelies on demand. The responsiveness of the XRT is instant, with effortless acceleration at any speed. Using the 1275kV motor, the XRT is ready to blast to speeds over 50mph!

Clipless Body Mounts

The clipless body mounting system adds to its user-friendly design, allowing for easy removal and installation in just seconds while ensuring a secure and strong lock in place. The body itself is reinforced with a cage to minimize flex and external skids to strategically protect it during intense bashing sessions. Due to its fusion of race-inspired design, exceptional durability, and powerful performance. Whether you're pushing the limits of speed or navigating challenging terrains, the XRT delivers confidence and control, making it a top choice for enthusiasts seeking an adrenaline-pumping RC monster truck experience and one of the best big-scale bashers on the market!

Trucks motor fried after third run. This truck for the price shouldn't be frying motors after three runs.

Rough, tough, powerful, and elegant. I would buy another one. I recommend this to anyone that can respect the power it has and has the space to use it. Amain delivered it fast. Top notch service. Thank you

Clifton MelerineVerified owneron Traxxas XRT 8S Extreme 4WD Brushless RTR Race Monster Truck (Black)

Best rc car I ever had this xrt is so nice and fast shipping! I might need another one.

Jake WoldVerified owneron Traxxas XRT 8S Extreme 4WD Brushless RTR Race Monster Truck (Black)

If your debating get the x Maxx instead. It's okay but it's not as fast as I thought, does handle well. Maybe if you upgrade to x. Maxx shocks and tires itll be more jumperable.

What reviewers say

Reviewers generally praise the Traxxas XRT 8S Extreme's power, handling and fast shipping, and several rate it five stars, with customer service also highlighted. Criticism is more mixed. One owner reported the body arrived scratched with chipped paint despite an undamaged package, and another reported a motor failing after three runs, which they felt was poor value at this price. A fourth reviewer found the truck less fast than expected and suggested upgrades to shocks and tires for jumping. Several reviews are brief, and a few mention shipping or delivery rather than the truck itself, so the evidence on durability is limited.

  • + Strong power
  • + Handles well
  • + Fast shipping
  • + Good customer service
  • − Body arrived scratched and chipped
  • − Motor failed after three runs
