Traxxas TRX-4 Sport High Trail Edition RTR 1/10 Crawler (Gray)

The Traxxas TRX-4 Sport High Trail Edition is a ready-to-run 1/10 crawler tuned for serious trail work. It pairs portal axles and a factory long-arm lift kit for maximum clearance, while the waterproof XL-5 HV speed control and Titan 550 motor keep power predictable on steep lines. Ideal for beginners (skill level 1) and experienced trail drivers who want a capable rig out of the box.

Key Features

• Tough, lightweight pickup body — High-angle bumpers increase clearance while the molded grille and tailgate keep a realistic look.
• LED-ready lighting — Headlight and taillight openings accept LED upgrades for night runs.
• Full nylon composite protection — Wheel wells and floor pans use composite materials to resist abrasion and impacts.
• Scale accessories — Rugged expedition rack with detailed accessories plus injection-molded snorkel and side mirrors add realistic utility.
• Clipless body mounting — Clipless design gives a smooth body appearance and lets the scale details attach directly to the internal frame.
• Trail-tuned XL-5 HV waterproof ESC — Fully sealed electronics with Traxxas EZ-Set one-button setup and a large heat sink for steady thermal performance.
• Five drive profiles — Sport, Race (no reverse), Training (reduced throttle/reverse), Trail (includes drag brake in neutral), and Crawl (instant reverse with max hill-hold brake).
• Two-stage low-voltage protection — Built-in LVD helps protect your battery under heavy load.
• Titan 550 21T reverse-rotation motor — High-torque brushed motor with internal cooling fan and preset gear mesh for reliable power delivery.
• Motor retention design — Motor is retained separately from gear mesh for easier service and consistent mesh settings.
• Portal axles — Raise ground clearance, reduce torque twist, use steel gears, and improve axle geometry to lower driveshaft strain.
• Shaft-driven 4WD — Full-time shaft drivetrain with tough 6 mm stub axles and steel front CV driveshafts for consistent traction.
• Hardened steel rear shafts & spool-locked diffs — Spool-locked front and rear differentials with a steel gear transfer case improve durability on heavy trails.
• Factory long-arm lift kit — Adds over 1 inch of clearance while keeping steering geometry precise and allowing 2.2" oversized wheels and tires.
• TQ 2.4 GHz transmitter — Ergonomic radio with internal antenna and Traxxas 6519 3-channel micro receiver with fail-safe security inside an O-ring sealed watertight box.
• Reinforced steel ladder frame — Full-length 1.5 mm steel frame rails with adjustable bumpers, width-adjustable rock rails, and integrated wire routing clips.
• Innovative battery compartment — Hinged battery strap for fast access, no removable pins, accepts different height packs and full-size long batteries; also accepts smaller 1/16 scale packs with an optional strap.
• Single-speed transmission — Steel gears, dual horizontal shafts, twin friction-plate slipper clutch, and easy removal for servicing.
• Chassis-mounted metal gear steering — 2075X digital metal-gear servo mounted to the chassis, delivers a 45° steering angle with direct steering and bump-steer-corrected geometry.
• Proven suspension layout — Front 3-link with Panhard bar and rear triangulated 4-link, using heavy-duty rod ends with steel hollow balls and 5 mm steel link rods with 4 mm threaded ends.
• Extended aluminum GTS shocks — Oil-filled coilover shocks with extra-long silver-anodized bodies, threaded collars for ride-height adjustment, O-ring cap seal and dual X-ring shaft seals for smooth damping and long service life.
• Oversize wheels & tires — 2.2" five-spoke wheels with replica beadlock rings fitted with pre-mounted 2.2" Canyon Trail tires, trail-tuned foam inserts and S1 rubber compound on 12 mm steel hex hubs.
• Sealed ball bearings — Bearing support throughout the drivetrain for reduced friction and longer life.
• Hex hardware with black oxide coating — Rust-resistant finish on hardware helps prevent corrosion from trail use.
• Requires battery and charger — Battery and charger are sold separately so you can choose the pack that fits your run time and weight preference.
