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

High-Strength 23T Servo Horn for Trail Use

This TRX4023TC aftermarket servo horn is made to upgrade TRAXXAS-style scale steering and to handle the tougher loads found in trail and rock crawling. Built from 7075 aluminium, the straight single-arm profile improves stiffness and repeatable steering feel versus stock plastic arms, while matching the common 23T servo spline.

The horn offers dual tie-rod mounting positions so you can shift the effective linkage geometry to dial steering responsiveness and toe. The package includes the stainless steel round head screws pictured in the product listing so installation does not usually require extra fasteners.

Fitment advice: seat the spline onto the servo output, try each tie-rod hole to establish preferred travel and centring, and tighten mounting screws to a sensible torque to avoid stripping threads in plastic servo housings. This item is designed for RC-scale models and improves steering precision on compatible TRAXXAS crawlers.
