TRX-4 Technology and Innovation-Now Available as a Kit!

The Traxxas TRX-4 Scale and Trail Crawler set the standard for off-road versatility with its radical design and rugged durability.

Build your own portal axles, high/low range transmission, and remotely locking differentials. All the parts are organized neatly in labeled bags with waterproof electronics and 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.
