25T Aluminum Steering Horn with Spring for TRX-4 Trail Crawlers TRX4025TA/2H by GPM  [TRX4025TA/2H]

Aluminium 25T steering horn for TRX-4 crawlers

This 25T aluminium servo horn is aimed at Trail Crawler setups based on TRX4 platforms, providing a tougher alternative to OEM plastic arms. The integrated spring cushions impacts passed through the steering linkage, reducing the chance of servo gear damage while maintaining the original spline interface for accurate steering control.

The kit includes the metal horn and the matching mounting hardware: the aluminium 25T spline horn, two stainless 3x12 round head screws, an aluminium collar and one 3mm metal washer. These components are intended for hobby-grade installs on servos with the correct spline and shaft sizes; verify compatibility before torqueing down fasteners.

Fitment note for TRX-4 installations: the added spring increases the horn body thickness versus standard arms. In the stock servo position you should reverse the support tie-rod orientation to ensure the horn clears nearby chassis parts. Doing so does not alter the front reverse steering gearbox location but prevents contact in certain stock arrangements.
