Brushless Monster Truck Speed Meets Legendary Durability

The Traxxas® X-Maxx® X-Monster 8S 1/6 4WD Brushless RTR Monster Truck Chassis delivers extreme power, durability, and advanced engineering. Built for rugged terrain and maximum control, it combines premium electronics, a strong drivetrain, and a reinforced chassis system. With its advanced features, this chassis is the foundation of a true high-powered RC experience. This chassis does not include a body, giving you the freedom to choose between the Traxxas Chevrolet® GMT400 CK Truck Body, Bigfoot® No. 8 Body, or the Ford® F-150® Truck Body (TRA7697 or TRA7691-series - sold separately). If you already have a custom-painted X-Maxx body, the X-Maxx X-Monster Chassis offers full compatibility with existing X-Maxx clipless bodies, offering a wide range of options to match your style.

Advanced Electronics

The X-Maxx X-Monster features a VXL-8s™ Waterproof Electronic Speed Control paired with the powerful Velineon® 1200XL Brushless Motor, providing 8S LiPo compatibility and speeds of over 50mph with the optional pinion gear. Advanced cooling systems include dual motor fans, aluminum slip-on heat sinks, and integrated heat dissipation for sustained performance. Traxxas Stability Management® (TSM) ensures precise handling by automatically correcting for spinouts or loss of traction. The TQi™ 2.4 GHz High Output Radio System, with Traxxas Link™ integration, provides full telemetry, adjustable sensitivity, and seamless model memory for up to thirty Traxxas Link-enabled vehicles, while the high-output 2085XL metal-gear steering servo delivers immense torque and reliability.

Drivetrain & Suspension

The drivetrain is engineered for strength, featuring hardened steel gears, heavy-duty constant-velocity (CV) driveshafts, and splined aluminum center driveshafts for consistent power delivery. Torque-Biasing Center Drive™ technology helps absorb shock loads and distributes torque evenly to all four wheels. The suspension is built for durability and performance, using reinforced arms, heavy-duty steel pins, and C-hub geometry that maximizes steering angle. Aluminum GTX™ Shocks with oversized bores provide excellent damping with adjustable spring retainers, sealed cartridges, and rugged construction designed to handle even the roughest terrain.

Retention System & Durable Chassis

The heavy-duty modular composite chassis provides a rigid yet serviceable platform with interlocking bulkheads and an integrated sealed driveline. For protection, energy-absorbing rubber bumpers and reinforced skid plates shield against harsh impacts, while nerf bars guard the sides from collision damage. Wheels and tires feature dual-profile monster truck rims with huge 8.6-inch belted chevron-pattern tires, designed with soft rubber for grip and internal belting to prevent ballooning at high speeds. Additionally, the Snap-Lock Battery Retention System offers tool-free, clipless security with adjustable pivoting hold-downs, keeping batteries locked firmly in place for maximum reliability.
