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. The new TRX-4
chassis kit combines the same innovative features as the RTR vehicle
with the fun and excitement of building your own kit. 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.
Easy to Follow Assembly Instructions
The
TRX-4 Chassis Kit isn’t just for expert hobbyists. Traxxas goes the
extra mile to make the full-color instruction book easy to follow and
fun to use. Each section corresponds to a labeled bag with step-by-step
assembly instructions. True-to-scale part illustrations and ruler charts
make it easy to differentiate between different screws, bearings, and
gears. Helpful assembly tips and clear illustrations take the
frustration out of the assembly process. Have fun on the workbench and
on the trail with the new TRX-4 Chassis Kit.
