TRAXXAS TRX4 Steering Servo Horn 7075 Aluminum 25T TRX4025TC by GPM  [TRX4025TC]

7075 aluminium 25T steering arm

This aftermarket servo horn suits TRAXXAS TRX4 Trail Crawler setups and is listed as model TRX4025TC from GPM. The straight-arm design is machined from 7075 aluminum to offer greater stiffness than stock plastic horns while matching the common 25-tooth servo spline used in many scale crawlers.

It installs as a direct steering replacement and features two tie-rod holes so you can alter leverage and steering arc during tuning. The part is intended for hobby RC use only and is not suitable for real vehicle steering systems.

To fit, remove the original horn, confirm the servo spline count and spline orientation, mount the aluminium horn to the servo spline, and secure with the provided screws. Check clearance and steering travel before full operation and recheck fasteners after first runs.
