Blue CNC Aluminum Servo Motor Arm Horn 25T AL Alloy for 1/8 1/10 RC Car Torque Metal Pro EMAX Servo Compatible with MG995 MG946R MG996R MG945 S3003 High-Strength Steering Servo Upgrade Part

Upgrade the steering reliability and response of your remote-controlled vehicle with the Blue CNC Aluminum Servo Motor Arm Horn 25T. Designed specifically for hobbyists and competitive racers operating 1/8 and 1/10 scale RC platforms, this high-performance servo horn eliminates the flex and stripping common with factory plastic steering arms. Whether you are tackling rough off-road terrain with a rock crawler or hitting high speeds on a touring car track, this metal servo arm ensures your steering inputs translate instantly and accurately to your wheels.

Engineered from high-grade billet aluminum, this servo horn undergoes a precision Computer Numerical Control (CNC) machining process to achieve tight tolerances and flawless structural integrity. The 25-tooth spline interface is broached to exact industry standards, engaging securely with the output shaft of popular standard-size servos such as the MG995, MG996R, MG945, MG946R, and Futaba S3003. Anodized in a striking blue hue, the surface layer penetrates the aluminum substrate to prevent oxidation, scratching, and wear from dust, dirt, and moisture. The arm features dual threaded linkage attachment holes, giving users the ability to micro-adjust the leverage ratio and steering throw distance without needing extra hardware modifications.

This servo arm features a standard 25-tooth internal spline configuration designed for universal compatibility with major servo brands. The overall length is optimized to provide sufficient mechanical advantage while clearing standard servo saver assemblies and chassis bulkheads. Threaded mounting holes accommodate standard hardware used in 1/8 and 1/10 scale steering linkages. The material composition is high-tensile aluminum alloy, selected specifically for its high strength-to-weight ratio.

This CNC aluminum servo horn is ideally suited for a wide variety of hobby and engineering applications. It is widely used in 1/10 scale buggies, short course trucks, monster trucks, and rock crawlers like the Axial SCX10, Traxxas models, and Tamiya kits. Additionally, it serves as an excellent mechanical linkage component in DIY robotics, pan-tilt camera mounts, and automated mechanism prototypes utilizing standard high-torque servo motors.

Before installation, ensure your servo output shaft is clean and free of debris. Align the 25T splines carefully with the servo shaft to avoid cross-threading or stripping the internal teeth. Use a drop of removable threadlocker (blue threadlocker) on the securing center screw to prevent vibrational loosening during heavy operation. Adjust your radio transmitter's end-point adjustments (EPA) carefully to prevent the servo from stalling against mechanical limits, which can cause internal gear damage despite the heavy-duty horn.
