Traxxas TRX-4 Blazer Crawler RTR 1/10 (Black)

The Traxxas TRX-4 Blazer Crawler is a 1/10 scale, ready-to-run trail truck built for serious trail use and scale looks. It ships with portal axles, a two-speed remote-shift transmission and waterproof electronics so you can tackle rocks, ruts and wet conditions right away. The detailed 1979 Chevrolet Blazer body and adjustable steel frame let you dial in stance and wheelbase for a wide range of trail setups.

Key Features

• Custom-painted 1979 Chevrolet Blazer body — faithful scale details including grille, chrome bumpers, side mirrors, door handles and wipers for authentic appearance.
• LED-ready headlight and tail light openings so you can add lighting later.
• Tinted windows and an authentic decal sheet for period-correct styling.
• Full nylon composite wheel wells and floor pans to resist trail wear and impacts.
• Trail-tuned XL-5 HV electronic speed control — fully waterproof design with multiple drive modes: Sport (forward/brake/reverse), Race (forward/brake/no reverse), Training (50% forward/100% brake/50% reverse), Trail (forward/brake/reverse with trail-tuned drag brake) and Crawl (forward/instant reverse with 100% hill-hold brake).
• EZ-Set one-button setup and a large heat sink for reliable operation under load.
• Wide voltage compatibility for common NiMH and LiPo pack sizes to match your battery choice.
• Titan 550 21T motor — reverse-rotation, high-torque brushed motor with internal cooling fan, preset gear mesh and independent motor retention for easy service.
• Portal axles — raise center ground clearance, reduce torque twist and improve axle geometry while using steel gears to withstand trail abuse.
• Drivetrain — full-time shaft-driven 4WD with 6 mm stub axles, steel front CV driveshafts and hardened steel rear axle shafts for long service life.
• Remote-locking steel gear differentials with cable actuation for on-trail locking control.
• Steel gear transfer case built for heavy use on technical terrain.
• TQi 2.4 GHz radio system — 4-channel transmitter with the 6533 5-channel micro receiver, fail-safe and telemetry ports; stores settings for up to 30 Traxxas Link enabled models and supports the optional Traxxas Link wireless module.
• Exclusive Cruise Control feature for relaxed trail driving and adjustable steering/throttle sensitivity and endpoints for precise control.
• Patented waterproof receiver box with easy-access plug keeps electronics safe in wet conditions.
• Rigid steel frame — 1.5 mm steel frame rails increase torsional rigidity and accept four wheelbase positions (300, 312, 324, 336 mm).
• Adjustable rear shock tower positions for short- or long-wheelbase setups, fore/aft bumper adjustment and width-adjustable rock rails with integrated wire routing clips.
• Innovative battery compartment — hinged battery strap for quick access with no pins to lose; accepts different battery heights, full-size long packs and, with optional straps, smaller 1/16 scale packs in the integrated compartments and front tray.
• Two-speed transmission — remote high/low shifting, dual horizontal shafts and twin friction-plate slipper clutch; designed to be removed easily for servicing.
• Steering — chassis-mounted 2075X metal-gear digital servo with direct steering for up to a 45° steering angle and corrected geometry to reduce bump steer.
• Suspension — front 3-link with panhard and rear triangulated 4-link; heavy-duty rod ends with steel hollow balls and 5 mm steel link rods with 4 mm threaded ends.
• Aluminum GTS shocks — oil-filled coilover units with silver-anodized, threaded bodies and collars to set ride height; O-ring cap seal and dual X-ring shaft seals for consistent damping.
• Wheels and tires — replica chrome Rally wheels with hub inserts and pre-mounted 1.9" Canyon Trail tires fitted with trail-tuned foam inserts using the S1 rubber compound and 12 mm steel hex hubs.
• Sealed ball bearings throughout the drivetrain and rust-resistant black oxide coated hex hardware for corrosion protection.
• Requires battery and charger (sold separately) — choose a battery and charger to match your preferred runtime and performance.
