Traxxas TRX-4 Blazer Crawler RTR Trail Truck (Orange)

The Traxxas TRX-4 Blazer Crawler RTR is a scale 1/10 trail truck built for real off-road lines and easy setup. It ships with waterproof speed control and a complete TQi radio system, so you can focus on driving tight lines and technical moves on day one. The detailed 1979 Chevrolet Blazer body and portal axle geometry give real clearance and scale looks without sacrificing drivetrain strength.

Key Features

• Custom-painted 1979 Chevrolet Blazer body — scale grille, chrome bumpers, side mirrors, door handles and wipers for authentic presence on the trail.
• LED-ready headlight and taillight openings let you add lighting for night runs or display.
• Tinted windows and an authentic decal sheet complete the scale appearance.
• Full nylon composite wheel wells and floor pans for corrosion resistance and light weight.

• One-button Traxxas EZ-Set setup and a large heatsink for consistent performance under load.
• Wide battery support — accepts a range of NiMH and LiPo packs to suit your run-time and power needs.
• Titan 550 21T reverse-rotation motor — built-in cooling fan, preset gear mesh and separate motor retention for reliable service and cooling.
• Portal axles raise center clearance, reduce torque twist and use hardened internal gears for strength.
• Drivetrain — full-time shaft-driven 4WD with tough 6 mm stub axles, front CV driveshafts and hardened rear axle shafts for long life.
• Remote-locking, cable-actuated 4-gear differentials for on-the-fly locker control while crawling.

• TQi 2.4 GHz radio system — 4-channel transmitter and 5-channel micro receiver (6533) with fail-safe and telemetry ports, plus Cruise Control and adjustable endpoints and sensitivity.
• Sealed receiver box with easy-access plug keeps the electronics protected from water and debris.
• Rigid steel frame — 1.5 mm frame rails that increase torsional stiffness and offer four wheelbase positions (300, 312, 324, 336 mm).
• Adjustable rear shock tower positions for short and long wheelbase setups; bumpers and rock rails are adjustable for stance and width.
• Innovative battery compartment — hinged strap for quick access, no loose pins, supports different height batteries and full-size long packs, plus an integrated and secondary front tray for smaller 1/16 packs (optional strap required).
• Two-speed transmission with remote shifting, dual horizontal shafts and twin friction-plate slipper clutch for smooth power delivery.
• Transmission designed for easy removal and servicing.
• Steering — chassis-mounted 2075X metal-gear digital servo, direct-steer design with a 45° steering angle and bump-steer corrected geometry.
• Suspension — front 3-link with panhard and rear triangulated 4-link, using heavy rod ends with steel hollow balls and 5 mm steel link rods with 4 mm threaded ends.
• Aluminum GTS shocks — oil-filled coilovers with silver-anodized, threaded bodies and collars for quick ride-height tuning; O-ring cap and dual X-ring shaft seals for long service life.
• Wheels & tires — replica chrome Rally wheels with hub inserts and pre-mounted 1.9" Canyon Trail tires on trail-tuned foam inserts using S1 rubber compound and 12 mm hex hubs.
• Sealed ball bearings throughout for smooth drivetrain operation.
• Hex hardware finished with a rust-resistant black oxide coating.
• Requires battery and charger (sold separately) — choose packs and a charger to match your desired run-time and power.
