TRAXXAS TRX4 Trail Crawler 25T Aluminum Servo Horn by GPM TRX416025L  [TRX416025L]

TRX4 Aluminum 25T Servo Horn Kit

This 6pcs aluminium servo horn kit is an RC-scale replacement and tuning part designed for TRAXXAS TRX4 Trail Crawler chassis, supplied by GPM model TRX416025L. The set replaces the stock straight steering arm with a machined 25T aluminum horn and includes an adjustable tie rod link that lets you fine‑tune steering geometry without modifying the servo spline or chassis mounts.

Key fit and role: the straight arm layout improves steering responsiveness on crawler setups by shortening the linkage path and reducing flex at the horn, while the four-position hole pattern provides incremental changes to steering throw and centring bias. The kit deliberately targets scale crawler setups where precise steering feel and simple mechanical adjustment are preferred over electronic compensation.

Contents provided in the source listing are included with the kit and should be used to assemble the horn and tie rod on the servo and steering linkage as supplied.
