Traxxas TRX-4 Sport Crawler RTR Trail Truck 1/10 (Tan)

The Traxxas TRX-4 Sport Crawler is a ready-to-run 1/10 trail truck that puts trail-capable features into an easy-to-drive package. It combines a rigid steel frame, portal axles for added ground clearance, and aluminum GTS coilover shocks to handle rough lines and technical rock sections. Whether you're learning to crawl or pushing a trail setup, the TRX-4 Sport delivers dependable performance and straightforward setup.

Key Features

• Tough, lightweight pickup truck body — low-profile bumpers increase clearance while red differential covers and D-rings add utility and style.
• Trail-tuned waterproof speed control — EZ-Set one-button setup with a large, efficient heat sink and wide battery compatibility for NiMH and LiPo packs; includes two-stage low voltage protection.
• Drive modes built for trails — 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-holding brake).
• Titan 21T reverse-rotation motor — high-torque brushed motor with internal cooling fan, preset gear mesh, and motor retention separate from gear mesh for easier maintenance.
• TQ radio system — ergonomic transmitter with internal antenna paired to a 6519 micro receiver that includes fail-safe security.
• Watertight receiver box — patented O-ring seal keeps the micro receiver dry on wet runs.
• Rigid steel frame — 1.5 mm thick steel rails increase torsional rigidity and allow four wheelbase positions: 300 mm, 312 mm, 324 mm, and 336 mm; rear shock tower positions adjust for SWB or LWB setups; bumpers and rock rails are adjustable for fit and clearance; wire-routing clips are integrated into the rails.
• Innovative battery compartment — hinged strap for quick access with no pins to lose, accepts different battery heights and full-size long packs, and includes an integrated compartment for smaller 1/16 scale batteries with an optional strap.
• Portal axles — increase center ground clearance, remove torque twist, use steel axle gears, and improve axle geometry to reduce driveshaft strain.
• Drivetrain — full-time shaft-driven 4WD with tough 6 mm stub axles, steel front CV driveshafts, hardened steel rear axle shafts, and spool-locked front and rear differentials for predictable traction.
• Steel gear transfer case — durable transfer case construction for long-term reliability.
• Transmission — single-speed transmission with steel gears, dual horizontal shafts, and a twin friction-plate slipper clutch that’s easy to remove for servicing.
• Steering — chassis-mounted 2075X metal-gear digital high-torque waterproof servo with a 45° steering angle, direct steering (no servo saver), and geometry tuned to reduce bump steer.
• Suspension — front 3-link with panhard bar and rear triangulated 4-link setup using 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 shocks exclusive to the TRX-4 chassis with silver-anodized threaded bodies and collars for easy ride-height adjustment, o-ring cap seals, and dual X-ring shaft seals for smooth damping on the toughest trails.
• Wheels and tires — rugged black 5-spoke wheels mounted with 1.9" Canyon Trail tires, trail-tuned foam inserts, S1 rubber compound for traction, and 12 mm steel hex hubs.
• Sealed ball bearings — smooth, low-friction performance throughout the drivetrain and hubs.
• Hex hardware with black oxide coating — rust-resistant fasteners for long-term durability outdoors.
• Requires battery and charger — battery and charger are sold separately so you can choose the pack that fits your driving style.
