Traxxas X-Maxx Monster Truck RTR 8S (Red)

Traxxas X-Maxx Monster Truck delivers full-size monster truck performance in a ready-to-run package — huge ground clearance, mammoth 8-inch tires, and 8S-capable power for jaw-dropping acceleration and top speeds. This rig is aimed at drivers who want unstoppable bashing ability and durable, serviceable components.

Key Features

• 8S-capable speed control — Waterproof VXL-class ESC supports extreme battery setups, has a built-in cooling fan, machined heat sinks, 10-gauge silicone wiring, integrated protection circuits, LED status indicators, and telemetry via Traxxas Link.
• Big Block brushless motor — High-torque Velineon motor with a 5mm output shaft, aluminum slip-on heat sink and dual cooling fans for sustained power and fast acceleration.
• High top speed potential — Capable of 50+ mph with the recommended dual-battery setup and the included optional spur gear for pace that matches the truck’s size.
• Traxxas Stability Management — Adjustable stability control that reduces spinouts and loss of control; set assistance from off to full from the transmitter for track or freestyle driving.
• TQi radio system — High-output 2.4GHz transmitter with Traxxas Link support, a telemetry-ready 5-channel micro receiver, dual channel-1 inputs, and adjustable rates and sensitivity for fine tuning steering and throttle response.
• Quick-install body mount — New pivoting rear latch removes body posts and clips for single-handed installation and reinforced protection during hard landings.
• Full-time shaft drive 4x4 — All-metal gears and CVDs transfer power reliably through the drivetrain; splined outdrives and a splined aluminum center driveshaft resist shock loads.
• Torque-Biasing Center Drive — Absorbs driveline shock and routes torque to load-bearing ring and pinion gears inside large, sealed differentials for greater durability.
• Heavy-duty gearing — Steel spur gear, large module ring and pinion gears, and fully machined aluminum stub axles for long-lived drivetrain strength.
• Secure wheel mounting — 24mm splined wheel hexes retained with clips and 17mm hex on the wheel outside for positive wheel retention.
• Preset motor mounting — New motor mount system with factory gear mesh settings; motor retention is separate from mesh so you don’t need manual adjustments.
• Modular composite chassis — Rigid, interlocking chassis and bulkhead design with the driveline sealed inside to keep out dirt and make servicing easier.
• Improved battery retention — No body clips or hook-and-loop straps; pivoting hold-downs adjust to battery size and integrate into the chassis top brace for added stiffness.
• Upgraded steering system — New steering bell cranks, a high-output servo wired into the receiver box, and a double-shear, bearing-supported servo horn for precise control under load.
• Purpose-built suspension — Long-arm geometry with double-shear strength at critical points, fixed camber and toe links, steel tie bars, C-hub geometry for maximum steering angle, and adjustable roll center.
• GTX shocks — Machined aluminum threaded shock bodies, extra-large bore and capacity, 5.2mm damper shafts, integrated lower wiper seals, adjustable upper spring retainers, and bolted lower spring perches for repeatable damping.
• Durable bumpers and skids — Energy-absorbing rubber front bumper, lower front and rear skids, and integrated nerf bars for side-impact protection.
• Massive wheels and tires — 8 x 4 x 4-inch all-terrain tires on dual-diameter wheels with a two-piece foam insert and a compound formulated for high-power 8S use; high-strength glue and bead design hold everything together.
