TRX-4 set the standard for off-road versatility with its radical design and rugged durability. The 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 remote-locking differentials. All the parts are organized neatly in labeled bags along 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. The TRX-4 Chassis Kit includes a full-color instruction book that’s 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. The TRX-4 Chassis Kit arrives ready to assemble with a full-color instruction guide, TQi 4-channel 2.4 GHz radio system, and complete waterproof electronics including servos, XL-5 HV ESC, and Titan 21T motor. Key parts like shocks and suspension links come pre-assembled to make building easy and fun. Clipless body mounting makes it easy to customize your TRX-4 kit with any accessory Traxxas 312 mm wheelbase body (sold separately). The hidden latching system provides clean, flowing lines for maximum scale realism. On the trail the clipless body holds tight when you need it, but releases in just seconds to access the chassis.
