Traxxas new High-Torque servos represent a huge power upgrade for the TRX-4. When installing either servo, it is required that you use the High-Voltage BEC kit (#2262) and a steel servo horn (#8247X) is recommended. Installing the BEC is easy with plug and play simplicity. The kit includes a larger receiver box cover to maintain total waterproof integrity and a Y harness for vehicles with LED light kits.
