Precision 25T Servo Horn for TRX4 Steering

This 25T aluminium servo horn is supplied as model TRX4025TA/3H for TRAXXAS TRX4 applications. Engineered for durability, the machined aluminium arm houses a spring element that reduces shock transmission to the servo during trail impacts, and three accurately spaced holes permit precise tie-rod geometry adjustments for different link layouts.

Technical installation notes: the integrated spring increases the horn thickness relative to stock plastic arms, which can necessitate reversing the support tie rod angle when mounted in the original TRX-4 servo location to achieve correct clearance. The component is designed to maintain the front reverse steering gear placement when installed correctly; confirm tie-rod alignment and measure link lengths before final assembly.

Package contents from the manufacturer include the 25T aluminium horn, stainless steel round head screws, an aluminium collar, and a 3mm metal washer suitable for a single-arm steering conversion or upgrade.

What spline and fit checks should I perform before fitting?

Verify the servo uses a 25T spline and inspect the horn flats for correct seating; ensure the servo output shaft fully engages the horn and that no lateral play exists prior to torqueing fasteners.

How does the integrated spring affect impact loads?

The spring absorbs peak forces from trail impacts, reducing shock transmitted to the servo gears and electronics; this improves component longevity but may alter transient steering feel, so re-tune link geometry as needed.

Are replacement fasteners available?

The kit includes stainless steel round head screws, an aluminium collar, and a 3mm washer; replacements or additional sets can be sourced through authorised parts channels if required.
