Traxxas XRT Ultimate Monster Truck RTR VXL-8s (Green)

The Traxxas XRT Ultimate Monster Truck is a purpose-built, high-speed monster truck that combines metal drivetrain hardware, big-bore aluminum race shocks, and Velineon brushless power for aggressive on- and off-road performance. Designed for experienced hobbyists (Skill Level 5), it hits 60+ mph when fitted with two high-capacity batteries (sold separately) and delivers the strength and control you need for bashing and racing.

Key Features

• Comprehensive 6061-T6 aluminum upgrades — C-hubs, steering blocks, rear hub carriers, differential housings, and motor mounts replace plastic parts for longer service life and better heat transfer.
• VXL-8s waterproof electronic speed control — tuned for extra punch at any RPM, with an integrated cooling fan, 3-LED status indicators, machined heat sink, powered accessory ports, 10-gauge silicone power wiring, and built-in protection circuits.
• Velineon 1200XL brushless motor — 4-pole, 1275 Kv sensorless design with a 5 mm output shaft, oversize aluminum heatsink and dual cooling fans to keep temperatures in check during hard runs.
• High top speed capability — designed to reach 60+ mph with two compatible high-capacity batteries and optional gearing (batteries sold separately).
• Traxxas Stability Management (TSM) — improves straight-line acceleration and braking on low-traction surfaces without dulling throttle response; adjustable from off to 100% from the transmitter.
• TQi 2.4 GHz 2-channel radio with factory wireless module — includes factory-installed telemetry sensors and a 5-channel micro receiver (6533) with fail-safe and integrated telemetry ports; housed in a patented waterproof receiver box with an easy-access plug.
• X-Truck Spec 8S driveline — machined, hardened steel pinion and spur gears; full-time shaft-driven 4WD; heavy-duty steel CV driveshafts with laser etching; beefed-up steel differential output cups; splined aluminum center driveshaft; and machined aluminum stub axles.
• Transmission — Mod-1 pinion and spur gear set with torque-biasing center drive for predictable power transfer.
• Maxx-Spec differentials — sealed, hardened steel bevel limited-slip design with large-scale steel ring and pinion gears; splined outdrives secured by external thru-bolts; new bulkheads and covers for increased bearing support.
• Rock-solid motor mounting — rigid aluminum motor mounts with preset gear mesh adjustment, four keyed pins to lock the motor, and motor retention separated from gear mesh for reliability.
• GTX aluminum race shocks — machined threaded bodies with extra-large bore and capacity, TiN-coated 5.2 mm damper shafts for smooth action, integrated lower wiper seal cartridge, aluminum upper spring retainers, machined shock caps with pivot balls, and bolted lower spring perches.
• WideMaxx suspension — extra-wide suspension arms molded from a cold-weather material for toughness, double-shear connections, high-strength steel suspension pins with retainers, 4 mm machined pivot balls, 7075-T6 aluminum front toe links, and oversized wheel bearings.
• Precision steering — 6061-T6 aluminum steering bellcranks paired with a 2085RL high-output metal-gear waterproof steering servo (650 oz-in torque at 6.0 V; 0.13 sec/60° at 6.0 V), a double-shear aluminum servo horn, heavy-duty servo saver spring, and dirt evacuation channels to keep components moving freely.
• Ultra-low center-of-gravity chassis — modular chassis with interlocking bulkheads and a flat-bottom layout for improved handling, heavy-duty interlocking skid plates, and reinforced shock tower buttressing.
• Dual snap-lock battery compartments — protect batteries from side impacts and accept secondary clip security for safe mounting during aggressive driving.
• ProGraphix clipless body — snaps into place in seconds with secure latches, rigid internal frame, dual high-capacity cooling ducts, molded reinforcements to resist tears, protective top skids, and a high-downforce rear wing.
• Heavy-duty bumpers and supports — reinforced front bumper, rear wing support, nerf bars for side-impact protection, and a heavy-duty wheelie bar with integrated carry handle.
• Wheels and Gravix tires — 7.4" Gravix belted race tires reduce ballooning at speed and give low sidewalls for sharp turn-in; mounted on 3.8" matte black XRT race wheels with high-strength glue/bead construction and massive 24 mm splined wheel hubs.
• Sealed ball bearings — installed throughout the drivetrain for smooth operation and reduced maintenance.
• Hex hardware with rust-resistant black oxide coating — corrosion-resistant fasteners for long-term durability outdoors.
