Traxxas Servo, digital high-torque 400 brushless, metal gear (ball bearing), waterproof TRX2255

Overview

The Traxxas High-Torque 400 Red servo is a premium digital brushless servo designed for RC enthusiasts who demand maximum performance and reliability from their RC car UK setups. This high-torque servo combines cutting-edge brushless motor technology with robust metal construction to deliver exceptional steering authority and control. Whether you're running a Traxxas ready to run RC truck, trail crawler, or high-performance basher, the TRX2255 offers the power and precision needed to tackle extreme applications with confidence. This is not just another servo upgrade—it's a complete performance transformation for your RC vehicle.

With over three times more torque than the standard #2075 servo, the High-Torque 400 servo is the perfect choice for demanding applications including the Unlimited Desert Racer, Slash, Stampede, and virtually any 1/10 Traxxas vehicle requiring extreme performance. The servo provides noticeably faster turning speed and works exceptionally well with Traxxas Stability Management (TSM) equipped vehicles. For those looking to replace the E-Revo's dual servos, this single #2255 unit delivers lighter weight, more torque, and lightning-quick steering response in one compact package.

What truly sets the Traxxas High-Torque 400 servo apart is its complete waterproof construction—not merely water resistant, but fully waterproof. This gives you the freedom to run your RC car UK anywhere, anytime, without fear of water damage. Power through streams and bogs with confidence whilst trucks equipped with water resistant servos are left on the sidelines. The servo drops into most 1/10 Traxxas vehicles with factory fit precision, making installation straightforward and seamless.

• Factory Fit Drop-In Installation — Engineered for seamless compatibility with most 1/10 Traxxas models, the servo features the correct mounting footprint and connectors for straightforward installation without modification or adaptation.
• TSM Compatibility — Works perfectly with Traxxas Stability Management equipped vehicles, enhancing the effectiveness of the electronic stability control system and improving overall vehicle handling and safety.
• Rapid Response Time — With a speed rating of 0.15 seconds per 60 degrees at 6.0V, this servo delivers lightning-fast steering response, critical for maintaining control during high-speed manoeuvres and precise technical driving.

Technical Performance

The Traxxas High-Torque 400 servo represents a significant engineering achievement in servo design for high-performance RC applications. The servo operates across a voltage range of 6.0 to 7.4V DC, allowing flexibility in power delivery depending on your vehicle's electrical system configuration. At 6.0V, the servo delivers 400 ounce-inches of torque whilst maintaining a response time of 0.15 seconds per 60 degrees of movement—performance metrics that place it at the forefront of high-torque servo offerings. The brushless motor technology eliminates the brush commutation losses found in traditional brushed motors, resulting in more efficient power conversion and better heat management during extended use. The servo weighs just 64 grams, making it an efficient power upgrade that doesn't add significant weight to your RC vehicle. The metal construction throughout the servo, combined with the anodised aluminium centre case, provides superior structural integrity and thermal management compared to plastic-cased alternatives. The 25-tooth output spline is the industry standard for Traxxas vehicles, ensuring compatibility with a vast array of servo horns and linkage systems. The plastic top and bottom sections are paired with the anodised aluminium centre, creating a hybrid construction that balances lightweight design with durability and heat dissipation. For those looking to install this servo in a TRX-4, Traxxas recommends using the High-Voltage BEC kit #2262 and a steel servo horn #8247X to ensure the vehicle can deliver sufficient power and the mechanical linkages can withstand the servo's substantial torque output. This servo is compatible with most Traxxas 1/10 scale electric models and can be used in Traxxas nitro models with rechargeable 5-cell battery packs, though it is not recommended for the X-Maxx due to that model's extreme power requirements.

Frequently Asked Questions

• Is the Traxxas High-Torque 400 servo fully waterproof for water crossings and wet weather RC driving? — Yes, the servo is completely waterproof, not just water resistant. Traxxas distinguishes between the two specifications, and this servo is fully sealed to prevent water ingress. You can confidently power through streams, bogs, and rainy conditions without fear of water damage to the servo's internal electronics and mechanical components.
• What voltage does this servo require and what battery should I use? — The servo operates across a range of 6.0 to 7.4V DC. This means it can work with standard 2S LiPo batteries (7.4V nominal) or 5-cell NiMH battery packs (6.0V nominal). For TRX-4 installations, you should use the High-Voltage BEC Kit #2262 to ensure adequate power delivery.
• How much faster and more powerful is this servo compared to standard Traxxas servos? — The High-Torque 400 provides over three times more torque than the standard #2075 servo, delivering noticeably faster turning speed and steering authority. The 400 ounce-inches of torque output makes it suitable for extreme performance applications where standard servos would struggle to maintain responsive control.
• Can I install this servo in a TRX-4 trail crawler? — Yes, the High-Torque 400 is compatible with TRX-4 models, and it represents a huge power upgrade for that vehicle.
