Traxxas TRX-4 Crawler 1979 Ford Bronco RTR (Red)

The Traxxas TRX-4 Crawler is a ready-to-run 1/10 trail truck built around an officially licensed 1979 Ford Bronco body and a purpose-designed TRX-4 chassis. It combines portal axles and a rigid steel frame for extra ground clearance and chassis strength, while waterproof electronics and the TQi radio system make it a dependable choice for both casual bashers and experienced trail drivers.

Key Features

• Official 1979 Ford Bronco body with scale grille, chrome bumpers, side mirrors, chrome side trim and windshield wipers for accurate on-trail appearance.
• Clear front and side windows and an authentic decal sheet for realistic detailing and easy customization.
• Full nylon composite wheel wells and floor pans that protect internals and keep body weight low.
• Trail-tuned XL-5 HV waterproof ESC 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 drag brake), and Crawl (forward/instant reverse with 100% hill-hold brake).
• EZ-Set one-button setup for quick ESC programming and a large heat sink for reliable thermal performance.
• Wide voltage range that supports common battery choices and two-stage low-voltage protection to help preserve pack life.
• Titan 550 21T reverse-rotation motor with internal cooling fan, preset precision gear mesh, and motor retention that’s separate from gear mesh for easier service.
• Portal axles to increase ground clearance, reduce torque twist, and use steel gears for strength.
• Axle geometry improvements that lower driveshaft strain and improve drivetrain durability.
• TQi 2.4 GHz radio system with a 4-channel transmitter and a 5-channel micro receiver (6533) offering fail-safe and integrated telemetry ports.
• Traxxas Link compatibility (optional wireless module sold separately) and automatic storage for up to 30 Traxxas Link-enabled models.
• Cruise Control feature for extended trail driving and adjustable steering/throttle sensitivity and endpoints for fine-tuned control.
• Patented waterproof receiver box with an easy-access plug to protect electronics from water and mud.
• Rigid 1.5 mm steel frame rails that increase torsional rigidity and allow four wheelbase positions (300 mm, 312 mm, 324 mm, 336 mm).
• Adjustable chassis layout with rear shock tower positions for short- and long-wheelbase setups, fore/aft bumper adjustment, and width-adjustable rock rails.
• Integrated wire routing clips in the frame rails to keep wiring tidy and secure on rough trails.
• Innovative battery compartment with a hinged strap for fast battery access, no pins to lose, accommodation for different battery heights, and room for full-length long packs.
• Secondary front battery tray accepts smaller 1/16 scale batteries (optional strap required) for compact power options or backup power.
• Full-time shaft-driven 4WD drivetrain with rugged 6 mm stub axles, steel front CV driveshafts and hardened steel rear axle shafts.
• Remote-locking steel-gear differentials with cable actuation and a steel gear transfer case for dependable torque distribution on technical terrain.
• Two-speed transmission with remote high/low shifting, dual horizontal shafts and a twin friction-plate slipper clutch that’s easy to remove for servicing.
• Chassis-mounted 2075X metal-gear digital steering servo delivering a 45° steering angle, direct steering (no servo saver), and bump-steer corrected geometry.
• 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 for strong, predictable articulation.
• Aluminum GTS oil-filled coilover shocks exclusive to the TRX-4 chassis with silver-anodized bodies, threaded collars for ride-height adjustment, smooth damping, O-ring cap seals and dual X-ring shaft seals.
• Wheels and tires: replica chrome wheels with hub inserts, pre-mounted 1.9" Canyon Trail tires on trail-tuned foam inserts using S1 rubber compound and 12 mm steel hex hubs for secure fitment.
• Sealed ball bearings throughout to reduce friction and wear under trail conditions.
• Hex hardware finished with rust-resistant black oxide for long-lasting fastener reliability.
• Requires battery and charger sold separately so you can choose the battery that fits your driving style and runtime needs.
