Traxxas TRX-4 Blazer Crawler RTR 1/10 Trail Truck (Red)

Traxxas TRX-4 Blazer Crawler is a ready-to-run 1/10 trail truck built for realistic trails and scale looks. It pairs a custom-painted 1979 Chevrolet Blazer body with portal axles, a two-speed transmission and rugged drivetrain so you can tackle rock gardens, roots and rough trails right away.

Key Features

• Custom-painted 1979 Chevrolet Blazer body — accurate grille, chrome-style bumpers, side mirrors, door handles and windshield wipers for authentic scale presence.
• LED-ready headlights and tail lights so you can add lighting for night runs or low-light trails.
• Tinted windows and an authentic decal sheet that finish the factory-correct look.
• Full nylon composite wheel wells and floor pans for impact resistance and lighter weight.
• Trail-tuned XL-5 HV waterproof electronic speed control — fully sealed for wet and muddy conditions and built with a large heat sink for reliable cooling.
• Multiple drive profiles on the XL-5: Sport (forward/brake/reverse), Race (forward/brake/no reverse), Training (50% forward/100% brake/50% reverse), Trail (forward/brake/reverse with drag brake) and Crawl (forward/instant reverse with 100% hill-holding brake).
• Traxxas EZ-Set one-button setup and two-stage low-voltage protection for simple, safe operation.
• Titan 550 21T reverse rotation motor — high-torque brushed motor with internal cooling fan, preset gear mesh and independent motor retention for easier service.
• Portal axles — raise center ground clearance, reduce torque twist and improve axle geometry while lowering strain on driveshafts; gears are steel for long life.
• Drivetrain — full-time shaft-driven 4-wheel drive with tough 6 mm stub axles, steel front CV driveshafts and hardened rear axle shafts for durable power delivery.
• Remote-locking, steel-gear differentials with cable actuation for on-the-fly traction control in varied terrain.
• Steel gear transfer case to handle torque and shifting loads.
• TQi 2.4 GHz radio system — 4-channel transmitter and 5-channel micro receiver (6533) with fail-safe and integrated telemetry ports.
• Radio stores settings for up to 30 Traxxas Link-enabled models and is compatible with the optional Traxxas Link Wireless Module for full app control (module sold separately).
• Exclusive cruise control for long trail runs and adjustable steering/throttle sensitivity plus endpoint adjustments to fine-tune handling.
• Patented waterproof receiver box with easy-access plug protects electronics when conditions turn wet.
• Rigid steel frame — 1.5 mm thick frame rails for torsional rigidity and four selectable wheelbase positions (300 mm, 312 mm, 324 mm, 336 mm).
• Adjustable rear shock tower positions for short- or long-wheelbase setups, bumpers that shift fore and aft, and rock rails that adjust for width.
• Integrated wire-routing clips in the frame rails keep wiring tidy and protected on the trail.
• Innovative battery compartment — hinged strap for fast battery access with no pins to lose, fits full-size long packs and accepts smaller 1/16 scale packs with optional straps; includes a secondary front tray for small packs.
• Transmission — two-speed high/low with remote shifting, dual horizontal shafts and a twin friction-plate slipper clutch for driveline protection and tunable feel.
• Transmission assembly is designed for easy removal and servicing.
• Steering — chassis-mounted 2075X metal-gear digital servo with a wide 45° steering angle, direct-steer setup (no servo saver) and geometry tuned to minimize bump steer.
• Suspension — front 3-link with Panhard bar and rear triangulated 4-link, using heavy rod ends with steel hollow balls and 5 mm link rods with 4 mm threaded ends for precise geometry and durability.
• Aluminum GTS shocks — oil-filled coilover design exclusive to TRX-4, silver-anodized threaded bodies with collars to adjust ride height, O-ring cap seal and dual X-ring shaft seals for smooth damping on technical lines.
• Wheels & tires — replica chrome Rally wheels with hub inserts and pre-mounted 1.9" Canyon Trail tires fitted with trail-tuned foam inserts and S1 compound for consistent traction.
• 12 mm steel hex hubs for secure wheel attachment and long life.
• Sealed ball bearings throughout reduce friction and simplify maintenance.
• Hex hardware finished with a rust-resistant black oxide coating for corrosion resistance after wet runs.
• Requires battery and charger (sold separately) — the RTR truck does not include a battery or charger.
