TRX4M Servos

Shop steering servos and separate servo horns for Traxxas TRX4M 1/18 crawlers. A horn is a steering linkage component; it is not a complete servo.

Choose a TRX4M steering servo

  • INJORA INJS2065 7 kg digital servo: listed as waterproof and supplied with its mounting bracket. Check voltage, dimensions and spline compatibility.
  • MEUS MEX-8 / MEX-12 micro servos: choose the MEX-8 coreless or MEX-12 brushless option. Listed torque reaches 8.5 kg or 12.5 kg respectively, depending on voltage. These servos use a 25T spline; check the product's power and mounting requirements.

Need a servo horn rather than a servo?

The INJORA 4M-12 CNC aluminum 25T horn and MEUS 25T metal horn are separate components. Confirm your servo's spline, horn length and steering geometry before ordering. Do not assume every stock or aftermarket servo uses 25T.
