Traxxas TRX-4 Bronco Crawler 1/10 RTR (Sunset)

The Traxxas TRX-4 Bronco Crawler brings a fully licensed 1979 Ford Bronco body to a proven TRX-4 trail platform, delivering scale looks and real trail capability right out of the box. This RTR is set up for slow, controlled crawling and tougher off-road lines thanks to portal axles, shaft-driven 4WD, and waterproof electronics.

Key Features

• Licensed 1979 Ford Bronco body with scale grille, chrome bumpers, side mirrors, chrome side trim and wipers for an authentic appearance.
• Clear front and side windows plus an authentic decal sheet to finish the stock look.
• Full nylon composite wheel wells and floor pans for lightweight protection; additional scale accessories available separately.
• Trail-tuned XL-5 HV waterproof ESC with a fully sealed design so you can run in wet conditions without worry.
• ESC drive modes include 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 hill-hold brake).
• Traxxas EZ-Set one-button setup, two-stage low-voltage protection, and a large heat sink for reliable performance under load.
• Titan 21T reverse-rotation motor with internal cooling fan for sustained torque and preset gear mesh for proper drivetrain alignment.
• Motor retention designed separately from gear mesh to simplify motor service and adjustments.
• Portal axles raise ground clearance and reduce torque twist while using hardened gear sets for strength.
• Portal axle geometry improves axle alignment and lowers stress on driveshafts for smoother drivetrain operation.
• TQi 2.4 GHz radio system with a 4-channel transmitter and a 5-channel micro receiver (6533) that provides fail-safe and integrated telemetry ports.
• Radio stores settings for up to 30 Traxxas Link enabled models and supports the optional Traxxas Link wireless module for app features (module sold separately).
• Exclusive Cruise Control for long trail runs and adjustable steering and throttle sensitivity and endpoints for precise control.
• Patented waterproof receiver box with an easy-access plug keeps electronics protected on the trail.
• Rigid steel frame with 1.5 mm thick frame rails for better torsional stiffness and four selectable wheelbase positions (300 mm, 312 mm, 324 mm, 336 mm).
• Adjustable rear shock tower positions for short-wheelbase and long-wheelbase setups, fore/aft bumper adjustment, and width-adjustable rock rails with integrated wire routing clips.
• Innovative battery compartment with a hinged strap for fast access, no loose pins to worry about, and room for different battery heights including full-size long packs; an integrated compartment accepts smaller 1/16 scale batteries with an optional strap.
• Secondary front battery tray accepts smaller 1/16 scale batteries with the optional strap for compact power options.
• Drivetrain is full-time shaft driven 4WD with 6 mm stub axles, front CV driveshafts, hardened rear axle shafts, remote-locking differentials actuated by cable, and a strong gear transfer case.
• Transmission features two-speed high/low range with remote shifting, dual horizontal shafts, and a twin friction-plate slipper clutch that is easy to remove for service.
• Steering uses a chassis-mounted 2075X metal-gear digital servo, delivers a 45° steering angle, uses direct steering (no servo saver), and corrects geometry to reduce bump steer.
• Suspension with a front 3-link plus panhard and a rear triangulated 4-link layout, heavy-duty rod ends with hollow balls, and 5 mm diameter link rods with 4 mm threaded ends for reliable articulation.
• Aluminum GTS shocks are oil-filled coilovers exclusive to the TRX-4 chassis, with silver-anodized, threaded bodies and collars to adjust ride height, O-ring cap seal and dual X-ring shaft seals for consistent damping.
• Pre-mounted replica chrome wheels with hub inserts and 1.9" Canyon Trail tires using trail-tuned foam inserts and S1 rubber compound for predictable traction; 12 mm hex hubs provide secure wheel mounting.
• Sealed ball bearings throughout and hex hardware finished with rust-resistant black oxide coating for long-term serviceability.
• Requires battery and charger (sold separately)—this RTR does not include the pack or charger.
