Traxxas TRX-4 Sport 1/10 4WD Electric Rock Crawler Assembly Kit

The Traxxas TRX-4 Sport is purpose built for trail-conquering RC fun with innovative technical features and rugged durability. The new TRX-4 Sport Unassembled Kit combines all the technical capability of the RTR truck, with the excitement of building your own kit. The TRX-4 Sport Kit assembles to form a roller chassis without electronics, battery, or charger. From mild to wild, enjoy ultimate build-it-yourself freedom to add your own motor, electronic speed control (ESC), servo, and radio system to the highly competent chassis. All the parts are organized neatly in labeled bags with pre-assembled shocks and suspension links. A fully illustrated color manual makes the kit as much fun to construct as it is to take off-road.

The Power of Portals:
Build your own game-changing TRX-4 portal axles with the TRX-4 Sport Kit. These innovative axles lift the chassis at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles (and not get stuck) your tires would need to be over an inch taller than the TRX-4’s. Straddling boulders with ease, the TRX-4 chassis takes the path less traveled and leaves everything else behind.

Torque Twist Eliminated:
Total axle gear reduction with portals is over twice non-portal designs, virtually eliminating torque twist. Portal axles transform the motor's power into straight, powerful, forward motion without twisting you off the rocks.

Canyon Trail 1.9 Tires:
The 1.9 Canyon Trail tires and tuned foam inserts are super-soft and grippy to deliver superior bite on rocky surfaces with convincing scale realism. A 12mm steel hex drives the wheels.

Pre-Cut Clear Body:

The TRX-4 Sport’s clear body comes pre-cut and ready to mount. The included window masking makes it easy to customize the body with your own polycarbonate paint. The detailed injection-molded grill and tail gate are LED-ready with clear (front) and colored (rear) lenses.:

Expedition Rack and Scale Accessories:
The TRX-4 Sport Kit includes rugged high-clearance front and rear bumpers with red D-rings and matching differential covers. The included Expedition Rack includes a full complement of replica accessories including a jack, gas cans, shovel, axe, snorkel, fire extinguisher, spare tire mount, and traction boards.

Extreme Capability:
Steep approach angles front and rear allow the TRX-4 Sport to tackle big obstacles head on. The front motor design biases weight forward for superior climbing ability.

Waterproof:
The TRX-4 Sport Kit includes a fully waterproof receiver box for your receiver (sold separately). Only Traxxas’ patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water in your electronics.
