Traxxas TRX-4 Chevrolet K5 Blazer RTR 1/10 (Blue)

Traxxas TRX-4 K5 Blazer is a ready-to-run 1/10 scale trail crawler that pairs authentic Chevrolet K5 Blazer styling with purpose-built off-road hardware. It comes trail-ready with portal axles, long-arm lift geometry and waterproof electronics — ideal for beginners and experienced drivers who want scale looks and capable trail performance.

Key Features

• Officially licensed 1979 Chevrolet K5 Blazer body — deep-inset front grille, chrome bumpers, side mirrors, door handles, side trim and windshield wipers deliver realistic scale presence on the trail.
• LED-ready lighting — headlights, tail lights and side markers are set up for LED upgrades to brighten night runs.
• Authentic decal sheet — scale graphics included to match the classic Blazer look.
• Full nylon composite wheel wells and floor pans — molded components that protect internals and keep the scale appearance clean.
• Clipless body mounting — smooth exterior lines thanks to clipless fasteners, with an internal body cage that adds rigidity and lets body details mount directly to the frame.
• Trail-tuned XL-5 HV waterproof speed control — fully waterproof electronics with Traxxas EZ-Set one-button setup, large heat sink and broad battery compatibility for reliable trail use.
• Five selectable drive profiles — Sport (forward/brake/reverse), Race (forward/brake/no reverse), Training (50% forward/100% brake/50% reverse), Trail (forward/brake/reverse with drag brake in neutral) and Crawl (forward/instant reverse with 100% hill-holding brake) let you adapt performance to terrain and skill level.
• Two-stage low-voltage protection — helps preserve battery life and prevents over-discharge during long runs.
• Titan 550 21T reverse-rotation motor — high-torque brushed motor with internal cooling fan, preset gear mesh and motor retention designed separately from the gear mesh for straightforward service.
• Portal axle design — raises ground clearance, reduces driveline twist and improves axle geometry while relying on hardened gears to handle torque.
• Full-time shaft-driven 4WD driveline — includes tough 6 mm stub axles, front CV driveshafts and hardened rear axle shafts for reliable power transfer.
• Remote locking differentials — steel-gear remote-locking diffs with cable actuation and a steel-gear transfer case let you lock and unlock traction on the fly.
• Factory-installed long arm lift kit — raises center clearance by over 1 inch, keeps steering geometry precise and makes room for oversize 2.2" wheels and tires.
• TQi 2.4 GHz radio system — 4-channel transmitter with 6533 5-channel micro receiver that adds fail-safe security, telemetry ports and automatic storage for up to 30 Traxxas Link enabled models.
• Traxxas Link compatible — accepts the optional wireless module for app access to settings, plus an exclusive Cruise Control feature and adjustable steering/throttle sensitivity and endpoints.
• Patented waterproof receiver box — easy-access plug and sealed protection for electronics when trails get wet.
• Reinforced steel ladder frame — full-length 1.5 mm thick frame rails with adjustable bumpers, width-adjustable rock rails and integrated wire-routing clips.
• Innovative battery compartment — hinged strap for fast access, no loose pins, fits different battery heights and accepts full-size long packs; also includes an integrated and a secondary front tray for smaller 1/16 scale packs with optional straps.
• Two-speed transmission with remote shifting — high/low range, dual horizontal shafts and a twin friction-plate slipper clutch that’s easy to remove for service.
• Chassis-mounted 2075X steering servo — metal-gear digital servo delivers a 45° steering angle, direct-steer setup (no servo saver) and bump-steer corrected geometry.
• Proven link suspension — front 3-link with panhard and rear triangulated 4-link, heavy rod ends with hollow steel balls and 5 mm diameter link rods with 4 mm threaded ends for durable articulation.
• Extended aluminum GTS shocks — oil-filled coilover shocks exclusive to TRX-4 with extra-long silver-anodized bodies, threaded collars to fine-tune ride height, O-ring cap seals and dual X-ring shaft seals for smooth damping.
• Oversize 2.2" wheels and tires — chrome mag-style 2.2" wheels with hub inserts, pre-mounted 2.2" Canyon Trail tires on trail-tuned foam inserts and S1 rubber compound for grip on rocks and dirt; fitted to a 12 mm steel hex.
• Sealed ball bearings — reduce friction and simplify maintenance on the drivetrain and wheel hubs.
• Hex hardware with rust-resistant black oxide coating — corrosion-resistant fasteners for trail conditions.
• Requires battery and charger (sold separately) — choose a properly sized pack to match your run time and weight preferences.
