GPM TRX4/TRX6 7075 23T Single-Arm Servo Horn - TRX4023TC - RC Spare Part  [TRX4023TC]

7075 Aluminum 23T Servo Arm for TRX4 Series

This TRX4023TC servo horn is an aftermarket aluminum replacement made for TRAXXAS scale steering setups and built to handle the increased loads of trail crawling. Machined from 7075 aluminum, the straight, single-arm profile gives a stiffer link between servo and linkage compared with factory plastic arms while using the common 23T spline found on many crawler servos.

The arm includes two tie-rod mounting holes so you can move the effective linkage position to fine tune steering throw and toe-in. It ships with the stainless steel round head screws shown in the product details so the horn mounts cleanly to the servo and secures the tie rod end without extra fasteners.

Installation tips: align the horn spline with the servo output, pick the tie-rod hole that produces the steering feel you want, and tighten screws to a moderate torque to avoid damaging plastic servo cases. This part is intended for RC scale models and improves steering precision and tie-rod geometry on compatible TRAXXAS crawlers.
