TRAXXAS TRX4 Servo Arm 25T Aluminium Tuning Part - TRX416025L by GPM  [TRX416025L]

TRX4 25T Servo Arm Upgrade

This 6pcs aluminium servo horn kit is a scale replacement and tuning item for TRAXXAS TRX4 Trail Crawler platforms, referenced as model TRX416025L. The kit swaps the stock straight steering arm for a machined 25T aluminium horn and supplies an adjustable tie rod link so you can fine tune steering geometry without changing servo endpoints or mounts.

Why it helps: the straight-arm design reduces the overall linkage length and cut down flex at the horn, yielding crisper steering at crawl speeds. The four-hole pattern provides step changes to throw and centring bias that are useful for dialing in handling on stone and technical lines.

Use the supplied hardware from the original listing to mount the horn and tie rod to your servo and steering linkage exactly as provided.
