This RC-grade 23T aluminium servo horn is intended for TRX4 steering assemblies and carries the part number TRX4023TA/3H. It replaces the OEM horn to give a more robust connection to the servo while an internal spring helps protect the servo gearset from shocks.
Constructed from 6061 T6 aluminium with a straight arm profile, the horn keeps weight down while improving resistance to bend at the output. The internal spring softens hard hits and the multiple mounting holes allow adjustments for tie rod geometry and steering throw.
Installation note: because of the internal spring the horn is thicker than thinner alloy types. On TRX-4 vehicles using the original servo location, reverse the support tie rod angle to achieve clearance; this change will not affect the front reverse steering gear position.
