New High-Torque Waterproof Metal Gear Servos

Traxxas new High-Torque servos combine maximum steering authority with a long list of high performance features. Both servos utilize full metal gears, dual ball bearings, and an aluminum center section for added heat dissipation. Traxxas High-Torque servos are fully waterproof, not just “water resistant” with a perfect factory fit in nearly all 1/10 scale Traxxas vehicles. High-Torque servos are fully compatible with Traxxas Stability Management (TSM) and provide noticeably faster steering response than stock servos.


The High-Torque Blue 330 features a powerful coreless motor for 330 ounce-inches of torque. The High-Torque Red 400 utilizes cutting-edge brushless motor technology for even faster transit speeds and a massive 400+ ounce-inches of torque for the most demanding applications. A single High-Torque Red 400 servo provides nearly double the power of the stock E-Revo servos combined and saves valuable weight. Both servos provide massive power for high-demand applications like the Traxxas Unlimited Desert Racer.

Waterproof Not "Water Resistant"

There is a major difference between “water resistant” and waterproof. Traxxas High-Torque servos are completely waterproof to give you the freedom to run when you want, where you want. Power through streams and bogs without fear while trucks with “water resistant” servos are stuck on the sidelines.


For TRX-4 Installation

Traxxas 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.
