TRAXXAS TRX4 Trail Crawler Aluminum 25T Servo Horn (4-Hole) by GPM TRX4025TL  [TRX4025TL]

Aluminum 25T servo horn for TRX4

This aluminum servo horn is an RC-scale replacement part produced by GPM for use with TRAXXAS TRX4 Trail Crawler steering systems. It uses 25T splines and a straight-arm form to increase rigidity compared with OEM plastic arms, making it suitable for trail crawling where repeated steering inputs and low-speed torque are common.

Key mechanical role: the horn provides a direct linkage between the servo output spline and the tie rod, and the four positioning holes allow incremental tie-rod length and steering ratio adjustments without swapping parts. The part is intended for tuning steering response and centering behavior on scale crawlers.

Installation notes: align the spline positions, secure the horn with the supplied fasteners, and confirm neutral steering before final tightening. Use thread-lock where metal-to-metal screws contact alloy surfaces if you prefer a more permanent fit, and check for bind at full lock after installation.
