• 3x14mm Ball Cup Screw Connection — The servo horn uses a 3x14mm BCS fitting, which is the standard connection type for Traxxas TRX-4 steering systems, ensuring perfect compatibility and a secure, repeatable fit that won't slip or wear prematurely during extended use.
• Single Piece Design — This is a complete, ready-to-install servo horn unit (1pc), meaning no assembly is required and you can mount it directly onto your servo to restore or upgrade your steering system without additional components or preparation.
• Genuine Traxxas Component — Manufactured by Traxxas, this part meets the same quality standards as original equipment, ensuring that your steering performance matches the precision engineering of your TRX-4 crawler platform.

Technical Performance

The Traxxas servo horn represents a critical component in the TRX-4 steering assembly, connecting your servo motor to the steering linkage and translating servo rotation into directional control inputs. Metal construction provides significant advantages over standard plastic alternatives in durability and longevity, particularly when operating in rocky terrain or during aggressive trail sessions where plastic horns can flex, strip, or crack under load. The 3x14mm ball cup screw connection offers a robust mechanical interface that resists wear and maintains precise alignment through countless steering cycles. UK RC enthusiasts will appreciate that this metal steering horn can handle the demands of serious TRX-4 operations, from casual weekend trail runs to competitive crawling events. The horn's geometry is engineered specifically for the TRX-4 steering geometry, ensuring that servo input translates to optimal steering response without binding or unusual leverage characteristics. When paired with quality servos such as the high-torque models commonly used in TRX-4 builds, this horn enables smooth, accurate steering control that directly translates to better vehicle handling and driver feedback.

If you own a TRX-4 platform, this servo horn is almost certainly compatible with your specific model.
• Why should I upgrade to a metal servo horn? — Metal servo horns offer superior durability compared to plastic alternatives, resisting bending, stripping, and cracking during heavy off-road use. Plastic horns can flex under load, compromising steering precision and eventually failing. Metal construction ensures your steering linkage remains rigid and responsive, delivering consistent directional control whether you're crawling rocks, bashing trails, or running competitive events. The investment in a metal horn pays dividends in reliability and vehicle performance.
• What servo should I use with this horn? — The TRX8247X servo horn is designed for standard TRX-4 servos with 3x14mm BCS connections. Users report successfully fitting this horn to high-torque servos such as the Power HD 23kg servo, which is popular in TRX-4 builds. When selecting a servo for your setup, ensure it has compatible connections and sufficient torque to deliver responsive steering without binding or stalling during tight articulation manoeuvres.
• Is installation difficult? — Installation is straightforward for anyone with basic RC maintenance experience. The servo horn simply mounts onto your servo spline using the 3x14mm ball cup screw connection. User reviews confirm that the horn fits perfectly and requires no special tools or modifications. If you're unfamiliar with steering linkage assembly, consult your TRX-4 manual or watch instructional videos to ensure proper connection and adjustment of steering throw.
• Will this improve my TRX-4's steering performance? — If you're replacing a worn or damaged plastic servo horn, upgrading to this metal version will restore precise steering response and improve overall vehicle control. The metal construction eliminates flex that can develop in plastic components over time, resulting in more direct and predictable steering. For new builds or preventative upgrades, a metal servo horn from the outset ensures you benefit from maximum steering rigidity and responsiveness from the first run.
