Overview
The Traxxas Servo Horn (Metal) TRX9740 is an essential upgrade component designed specifically for TRX-4M scale RC crawlers and trail trucks. Whether you own a 1/18 Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150, this metal servo horn replacement is engineered to deliver the precision steering control that serious RC enthusiasts demand. As a UK RC hobby retailer, we recognise that steering performance is critical for trail driving, rock crawling, and technical off-road courses, making this upgrade one of the most effective tuning modifications you can make to your TRX-4M platform.
The standard plastic servo horn on Traxxas TRX-4M models can flex under load, particularly when navigating challenging terrain or executing tight steering inputs during competitive trail events. This flex translates to imprecise steering response and inconsistent handling characteristics, which can cost you valuable seconds on the course or compromise your control during technical climbs. The metal servo horn TRX9740 directly addresses this weakness by replacing the flexible plastic component with a rigid metal construction that maintains steering precision in all conditions. For anyone serious about getting the best performance from their ready to run RC trail truck or crawler, this is a worthwhile investment.
Installing the metal servo horn is straightforward and requires no special tools or advanced mechanical knowledge. This makes it an ideal upgrade for both experienced RC tuners and enthusiasts looking to improve their setup without extensive modification work. Available now at RC Model Shop, the Traxxas TRX9740 fits seamlessly into your existing TRX-4M platform and works with all current versions of this popular 1/18 scale crawler family.
Key Features
- Metal Construction — The servo horn is manufactured from precision metal rather than plastic, providing superior rigidity and eliminating flex that occurs when steering load is applied during cornering, climbing, or technical manoeuvres. This rigid construction ensures that steering input is transferred directly to your steering linkage without any play or delay, resulting in more responsive and predictable vehicle behaviour.
- Eliminates Flex — The primary engineering benefit of upgrading to metal is the complete elimination of steering flex, which is a common issue with standard plastic horns. By removing flex from the steering system, you gain immediate improvements in steering precision and consistency, whether you are driving on rocks, sand, or mud.
- Increases Steering Precision — With flex eliminated, every steering input from your radio transmitter is executed with accuracy. This enhanced precision is particularly valuable during competition driving, tight technical sections, and rock crawling where millimetre-level steering accuracy can make the difference between clearing an obstacle cleanly or getting stuck.
- Direct Compatibility — This metal servo horn is specifically designed for the TRX-4M platform and is compatible with all TRX-4M variants including the Ford Bronco in multiple colours (blue, red, orange, black, white, Area 51), Land Rover Defender in multiple colours (green, light blue, pink, silver, tan, black), Chevrolet K10 High Trail Truck (blue, red, black), Ford F-150 High Trail Truck (black, brown, blue), and TRX-4MT Monster Truck variants (K10 and F150 in red and black).
- OEM Traxxas Quality — As an official Traxxas replacement part, this servo horn meets the manufacturer's strict quality standards and engineering specifications, ensuring perfect fitment and reliable long-term performance in your TRX-4M crawler.
Technical Performance
The Traxxas Servo Horn (Metal) TRX9740 represents a focused engineering solution to a specific performance limitation in the TRX-4M chassis design. The original plastic servo horn, whilst adequate for casual driving, exhibits deflection under steering load, particularly during aggressive cornering, rock crawling, and high-speed trail runs. This flex introduces a delay between steering input and vehicle response, reducing precision and making the vehicle feel less responsive than its capabilities should allow. The metal construction of the TRX9740 eliminates this deflection entirely, maintaining a rigid connection between the servo and the steering linkage under all driving conditions. The precision-engineered metal design is compatible with standard TRX-4M servo installations and integrates seamlessly into your existing setup without requiring modifications to other steering components. The metal material also provides superior durability compared to plastic, reducing the risk of component failure during aggressive driving or high-impact terrain interactions. For serious RC trail enthusiasts using ready to run RC vehicles in the UK, this upgrade delivers measurable improvements in steering feel, responsiveness, and overall vehicle control. The engineering principle is straightforward: eliminate flex, gain precision. This is exactly what the TRX9740 achieves through its metal construction approach.

Frequently Asked Questions
- Will the metal servo horn improve steering performance on my TRX-4M? — Yes. The metal construction eliminates flex present in the standard plastic servo horn, resulting in more precise steering response and better control during trail driving and rock crawling. You will notice improved steering accuracy immediately after installation, particularly during technical sections and aggressive cornering.
- Which TRX-4M models is this servo horn compatible with? — The Traxxas TRX9740 metal servo horn is compatible with all TRX-4M variants, including the 1/18 Ford Bronco (all colours), 1/18 Land Rover Defender (all colours), 1/18 Chevrolet K10 High Trail Truck, 1/18 Ford F-150 High Trail Truck, and TRX-4MT Monster Truck variants. If you own any TRX-4M scale ready to run RC crawler or trail truck, this part will fit your vehicle.
- Is installation difficult? — No. The metal servo horn replaces the existing plastic servo horn using the same mounting point and connection method. Installation requires only basic hand tools and takes just a few minutes. No modifications to your chassis or servo are necessary, making this one of the easiest upgrades to install on your TRX-4M.
- What is the difference between the metal and plastic servo horns? — The key difference is material rigidity. The plastic servo horn flexes under steering load, introducing delay and reducing precision. The metal servo horn in the TRX9740 eliminates this flex entirely, providing immediate improvements in steering response and control. The metal construction also offers superior durability and resistance to impact damage during rock crawling and technical driving.
- Will this upgrade help me in RC competitions? — Yes. Steering precision is critical in competitive RC trail driving and rock crawling events. By eliminating flex and improving steering response, the TRX9740 metal servo horn can help you navigate technical sections more cleanly and consistently, potentially improving your lap times and competition results.
- Is this part genuine Traxxas? — Yes. The TRX9740 is an official Traxxas replacement part manufactured to the company's quality standards. When you purchase from RC Model Shop, you are receiving a genuine product backed by Traxxas manufacturing quality.
