TRAXXAS TRX4 Trail Crawler Aluminum 7075 23T Servo Horn by GPM TRX4023TC  [TRX4023TC]

Aluminum 23T Servo Horn for TRX4

This GPM TRX4023TC servo horn is an aftermarket aluminum replacement designed for scale TRAXXAS steering systems, made to withstand the higher loads encountered in trail crawling setups. The single-arm, straight-profile horn is machined from 7075 aluminum for improved stiffness compared with typical plastic arms, and the 23T spline matches standard 23-tooth servo outputs used in many crawler servos.

The horn features a dual-hole tie-rod mounting layout that lets you shift the effective tie-rod position for fine steering response tuning and toe adjustment. It ships with the basic stainless steel round head screws shown in the product source to secure the arm to the servo and to attach the tie rod end, so you can swap the arm without sourcing additional fasteners.

Installation notes: align the spline on the horn with the servo output, select the tie-rod hole that yields the desired steering throw, then torque fasteners to a moderate setting to avoid stripping threads in plastic servo cases. This part is for RC-scale models only and is intended to improve steering precision and tie-rod geometry on compatible TRAXXAS crawlers.
