Traxxas X-Maxx Monster Truck RTR 8S (Rock n Roll)

The Traxxas X-Maxx Monster Truck is a Maxx-scale, 8s-capable RTR built for top-end speed and heavy-impact handling. With Traxxas Link telemetry and the included TQi radio, you get real-time data and on-the-fly adjustments while the shaft-driven 4WD and Velineon powertrain handle the power. This rig suits experienced drivers who want a tuneable, high-performance monster truck for bashing and big jumps.

Key Features

• 8s capable powertrain — designed to accept high-voltage setups for maximum speed and torque.
• 50+ MPH potential when run with two high-capacity batteries and the optional spur/pinion gear for top-end tuning.
• 5 mm motor output shaft for reliable torque transfer to the drivetrain.
• Aluminum slip-on heat sink to help shed heat from the motor under heavy loads.
• Dual motor cooling fans that keep temps down during extended high-speed runs.
• Traction control assist that reduces spinouts and helps maintain stability at speed, adjustable from off to full via the transmitter.
• Traxxas Link enabled for telemetry, data logging and model memory across multiple vehicles.
• TQi radio and TSM receiver — a 2.4 GHz transmitter/receiver combo with fail-safe and telemetry ports for real-time feedback.
• Model memory automatically stores settings for up to 30 Traxxas Link-enabled models so you can switch rigs without reprogramming.
• Multi-function knob and adjustable dual rates for steering and throttle let you tailor control feel instantly.
• Built-in cooling fan on the electronics for extra temperature management.
• Adjustable exponential settings for steering and throttle provide smoother low-speed control or aggressive response at the sticks.
• BEC voltage and motor temperature sensor installed for accurate telemetry data.
• Quick one-hand body installation using a pivoting rear latch for fast access to the chassis.
• Real-time telemetry via Traxxas Link shows motor temp, battery voltage and more while you drive.
• Precision heat sinks and machined cooling surfaces to improve thermal performance.
• 10-gauge silicone wiring for high-current paths and long-term reliability.
• Integrated protection circuits and LED status lights to help diagnose issues quickly.
• Big Block brushless motor — 4-pole, 1275 kV configuration for strong acceleration.
• Heavy-duty modular composite chassis constructed to absorb impacts and simplify repairs.
• No body posts or clips — the body mounts are eliminated for a clean look and faster swaps.
• Full-time shaft-driven 4WD that delivers consistent traction to all four wheels.
• All-metal gears and CVDs for drivetrain strength under high torque.
• Torque-Biasing Center Drive that soaks up impacts and balances power delivery front-to-rear.
• 24 mm splined wheel hexes retained with clips and featuring 17 mm hex on the wheel exterior for secure mounting.
• Sealed silicone fluid-filled differentials with large-module ring and pinion gears for controlled slip and durability.
• Splined outdrives with thru-bolt attachment for a positive, serviceable connection.
• Cush Drive with steel spur gear to smooth shock loads and protect the drivetrain.
• Fully machined aluminum stub axles and a splined aluminum center driveshaft for precise power transfer.
• Preset gear mesh eliminates the need for manual adjustments while motor retention is independent of gear mesh.
• Interlocking front and rear bulkheads and motor mounting to the rear bulkhead reduce flex and gear crunching.
• Service-friendly layout — components are easy to access for maintenance and repairs.
• Sealed driveline keeps dirt and grit out of critical moving parts.
• Pivoting battery hold-downs that adjust for battery size and lock securely without straps or clips.
• Chassis top brace integration improves battery tray support and overall stiffness.
• Front energy-absorbing rubber bumper and lower skids front/rear for abrasion and impact resistance.
• High-strength bead and glue tire construction plus integrated nerf bars to protect against side impacts.
• High-output steering servo mounted inside the RX box with a new support system and a double-shear, bearing-supported servo horn for durability.
• Wiring concealed in the RX box for a tidy chassis and better protection.
• Suspension engineered for travel and steering with double-shear critical points and high-strength steel suspension pins whose retainers resist backing out.
• 4 mm pivot balls and C-hub/steering-block geometry that maximize steering angle and handling.
• Adjustable roll center and fixed camber/toe links with steel upper and lower tie bars for consistent alignment.
• Full-contact sealed bearings used where durability matters most.
• Precision aluminum-threaded shock bodies with extra-large bore, 5.2 mm damper shafts and lower seal cartridges that include wiper seals for long life.
• Adjustable upper spring retainer, plastic shock caps with pivot balls, fixed shock locations and bolted lower spring perches for repeatable suspension setup.
• 8 x 4 x 4 inch all-terrain tires on large dual-diameter wheels formulated specifically for high-voltage 8s running, with a 2-piece foam insert for consistent performance.
