Key Features
- Milled from high-grade 6061-T6 aluminium — The servo horn is machined from aerospace-quality aluminium alloy that offers an exceptional strength-to-weight ratio, ensuring your steering system remains responsive whilst withstanding the intense forces generated by high-power servo upgrades and aggressive driving styles.
- Double-shear aluminium construction — This engineering approach provides superior rigidity and load distribution across the servo mounting points, meaning your steering inputs translate more directly into vehicle response without flex or deflection that could compromise precision.
- 46mm assembled steering linkage with pivot balls — The steering linkage arrives fully assembled with quality pivot balls already installed, eliminating the need for time-consuming assembly and reducing the risk of installation errors, getting you back on the track or trail faster.
- Brilliant anodised finish — Beyond the striking visual appearance that adds colourful style to your RC build, the anodised coating provides essential protection against corrosion, oxidation and wear, ensuring your servo horn maintains its performance and appearance through extended use.
- Perfect upgrade for high-power servos — Purpose-engineered to work optimally with upgraded servo platforms, this horn allows you to safely extract maximum performance from high-torque servo installations without risking component failure or steering system degradation.
- Compatible with 7746 and 7843 aluminium bellcranks — The servo horn integrates perfectly with Traxxas' upgraded bellcrank range, allowing you to create a completely optimised steering system where every component works in harmony for maximum precision and durability.
- Genuine Traxxas factory fit and finish — Manufactured by Traxxas for Traxxas vehicles, every servo horn is engineered to OEM specifications, guaranteeing perfect compatibility, no fitment issues, and the confidence that your upgrade will perform exactly as intended.
- Fits X-Maxx and XRT platforms — Whether you're running the legendary X-Maxx monster truck, the hardcore XRT rock racer, or their various Ultimate and specialist variants, this servo horn delivers the upgrade precision these vehicles demand.
Technical Performance
The Traxxas TRX7747 servo horn represents the pinnacle of precision steering component engineering for high-performance RC vehicles. Machined from 6061-T6 aluminium, this material choice reflects decades of aerospace and motorsport engineering expertise, delivering the ideal balance between weight reduction and structural rigidity. The double-shear construction methodology distributes lateral loads across a larger contact area, preventing the bending or flexing that can occur with single-shear designs or plastic components. This is particularly important when you're running high-torque servo upgrades that generate significant forces during rapid steering inputs or when navigating challenging terrain. The pre-assembled 46mm steering linkage with integrated pivot balls arrives ready to install, incorporating quality bearing surfaces that minimise friction whilst maintaining precise alignment tolerance. The brilliant anodised finish isn't merely cosmetic; it represents a hardened oxide layer that provides genuine corrosion resistance and durability in challenging environments, from dusty desert trails to wet UK weather conditions. The servo horn integrates seamlessly with Traxxas' evolved steering architectures, particularly when paired with upgraded 7746 and 7843 bellcranks, allowing you to create a completely optimised steering package where precision and response are maximised across all driving scenarios from casual backyard bashing to competitive racing applications.

Frequently Asked Questions
- What vehicles is the Traxxas TRX7747 servo horn compatible with? — The TRX7747 is designed for X-Maxx and XRT platforms, including the X-Maxx Ultimate, X-Maxx brushless models, XRT VXL-8S variants, XRT Ultimate editions, and compatible with specialist models including Funco Motorsports Pro Scale and X-Monster chassis derivatives. Always verify your specific vehicle model before ordering to ensure compatibility.
- Why should I upgrade from the stock plastic servo horn to this aluminium component? — The stock servo horn on most vehicles is plastic and designed for general use, but when you install a high-power servo upgrade, the increased torque and force loads can cause plastic horns to flex, break, or strip under pressure. The 6061-T6 aluminium construction of the TRX7747 is significantly more rigid, eliminating flex, providing more direct steering response, and capable of handling the extreme forces from upgraded servos without degradation or failure. Additionally, the machined aluminium offers a more professional appearance and superior corrosion resistance.
- Is the steering linkage pre-assembled, or do I need to assemble it myself? — The 46mm steering linkage comes fully assembled with pivot balls already installed and ready to use. This saves considerable assembly time and reduces the risk of incorrect installation, meaning you can upgrade your steering system quickly with confidence that everything is properly configured from the factory.
- What bellcranks does this servo horn work with? — The TRX7747 servo horn integrates perfectly with Traxxas upgraded 7746 and 7843 aluminium bellcranks. If you're planning a comprehensive steering upgrade, pairing this servo horn with these compatible bellcranks creates a completely optimised system where all components work in harmony for maximum precision, responsiveness and durability.
- Will this servo horn improve my vehicle's handling? — Yes, the rigid 6061-T6 aluminium construction eliminates the flex present in plastic horns, meaning your steering inputs translate more directly into vehicle response. This results in more precise handling, better feedback through the radio system, quicker directional changes, and more predictable cornering characteristics, particularly noticeable when driving at high speeds or in competitive environments.
- Is this suitable for beginners? — Whilst this is a genuine Traxxas upgrade component that any RC enthusiast can install, it's primarily designed as an upgrade for vehicles already running high-power servos. Beginners with stock vehicles and standard servos don't necessarily need this upgrade, but if you're planning to upgrade your servo as part of an enhanced build, this is the ideal matching component to ensure your steering system can handle the increased performance demands.
- What is the difference between this servo horn and aftermarket alternatives? — This is a genuine Traxxas factory component engineered by Traxxas specifically for Traxxas vehicles. It guarantees perfect fit, finish and compatibility without any modifications or adjustments. Many aftermarket alternatives require fitment work, aren't designed with the same precision tolerances, or lack the engineering rigour of genuine components. By choosing the TRX7747, you're choosing a component designed and validated by the manufacturer of your vehicle.
- Can I use this servo horn with servos other than Traxxas servos? — Yes, the servo horn's standard servo spline means it's compatible with most quality digital and analogue servos from various manufacturers. However, it's specifically engineered to work optimally with Traxxas servo platforms and their electrical characteristics. Always verify that your servo's spline and mounting configuration match the TRX7747 before installation.
