Optional extras are never added for you: Upgrades for the TRX-4 Crawler Kit
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.
