TRX4/TRX6 23T 7075 Servo Horn Single-Arm for Steering Tuning - TRX4023TC by GPM  [TRX4023TC]

Precision 7075 23T Servo Horn for Scale Crawlers

The TRX4023TC is an aftermarket 23T single-arm servo horn designed to upgrade TRAXXAS-style steering assemblies for scale crawling. Machined from 7075 aluminium, the straight profile increases steering rigidity compared with factory plastic arms while maintaining compatibility with standard 23-tooth servo outputs.

Its dual tie-rod holes let you alter the effective linkage point to refine steering response and toe settings. The unit comes with the stainless steel round head screws shown in the listing so you can install the arm without sourcing additional fixings.

Assembly guidance: fit the horn spline to the servo output, test both tie-rod positions to find the best steering travel, and apply moderate torque to mounting screws to avoid damaging plastic servo cases. This part is intended for RC-scale machines to enhance steering accuracy and linkage geometry on compatible TRAXXAS crawlers.
