Key Features
- Milled from high-grade 6061-T6 aluminium — This aerospace-grade aluminium alloy is renowned for its excellent strength-to-weight ratio, corrosion resistance and durability, ensuring your servo horn will withstand the demanding conditions of off-road RC driving without flexing or breaking under load.
- Perfect upgrade for high-power servos — Designed specifically to handle the increased torque and force generated by modern high-power brushless servos, this servo horn provides a robust connection that won't strip or fail when you demand maximum steering response from your RC vehicle.
- Brilliant anodised finish — The grey anodised coating not only protects the aluminium from corrosion and wear, but also provides a distinctive professional appearance that looks premium on your RC car UK setup and resists fading and scuffing through regular use.
- Double-shear design — The double-shear construction provides superior strength and load distribution across the servo horn, reducing the risk of failure during aggressive steering inputs and ensuring reliable performance lap after lap.
- Premium quality construction with factory fit and finish — Every aspect of this servo horn is manufactured to strict tolerances ensuring it fits perfectly with your existing Traxxas components right out of the box, with a finish quality that matches factory-original parts.
- Compatible with 7746 and 7843 aluminium bellcranks — This servo horn integrates seamlessly with Traxxas's upgraded aluminium bellcrank options, allowing you to build a complete high-performance steering system that works in perfect harmony.

Technical Performance
This servo horn represents the pinnacle of Traxxas engineering for steering systems on their largest and most powerful RC vehicles. Machined from premium 6061-T6 aluminium alloy, the material selection ensures the component delivers exceptional rigidity while remaining lightweight — critical for maintaining responsive steering feel in high-speed off-road situations. The grey anodised finish is applied through an electrochemical process that creates a protective oxide layer, extending the component's lifespan and maintaining its appearance through countless hours of bashful RC driving. The double-shear design distributes forces more effectively than single-shear alternatives, making it ideal for the extreme steering angles and forces generated by high-power upgraded servos. The servo horn's geometry has been precisely engineered to integrate perfectly with Traxxas's 7746 and 7843 aluminium bellcranks, creating a harmonious steering linkage system that maximises precision and minimises binding. Whether you're upgrading from stock plastic components or simply want the best performance available, this servo horn delivers the precision and durability expected from a genuine Traxxas upgrade component for X-Maxx and XRT vehicles.

Frequently Asked Questions
- Is the Traxxas TRX7747-GRAY servo horn compatible with my X-Maxx or XRT? — Yes, this servo horn is specifically designed for and compatible with X-Maxx Ultimate, X-Maxx Belted 4WD, XRT Ultimate and XRT VXL-8S models. It also works with the X-Monster chassis and Funco Motorsports Pro Scale vehicles. Always check your specific model number to ensure compatibility before purchasing.
- What is the benefit of upgrading to this aluminium servo horn? — The 6061-T6 aluminium construction provides significantly greater strength and durability compared to plastic servo horns, making it ideal if you've upgraded to a high-power brushless servo. The double-shear design prevents flexing and ensures consistent steering precision, which is particularly important for high-speed driving and competitive racing where steering response is critical.
- Does this servo horn come with all installation hardware? — The servo horn itself is included in the package. You'll need to ensure you have compatible bellcranks (7746 or 7843 models recommended) and a compatible servo to complete your steering system. Standard Traxxas servo horns use industry-standard spline connections, so installation is straightforward for anyone familiar with RC vehicle maintenance.
- Why should I choose the grey anodised finish? — The anodised finish provides excellent corrosion resistance and durability, protecting the aluminium from the elements and keeping your RC car UK looking professional. The grey colour offers a distinctive appearance while being more practical than lighter finishes for hiding dust and dirt from off-road driving.
- Is this servo horn suitable for beginners? — While this is a premium upgrade component, it's suitable for anyone with basic RC maintenance knowledge. If you're new to upgrading RC vehicles, we recommend having an experienced friend help with installation or consulting Traxxas's detailed assembly guides. The component itself is robust and forgiving to work with.
- What's the difference between this servo horn and stock plastic alternatives? — Stock plastic servo horns flex under load, which can result in imprecise steering and potential failure under the demands of high-power servos and aggressive driving. This 6061-T6 aluminium horn eliminates flex, maintains consistent geometry under load, and provides superior longevity — making it the preferred choice for anyone serious about RC performance.
