This 7075 aluminium servo horn is an aftermarket replacement designed specifically for TRAXXAS MAXX Monster Truck models, supplied as a 3pcs set TXMS025T75. Manufactured from 7075 aluminium to increase structural stiffness and wear resistance over stock plastic arms, the horn mounts at the servo to stabilise steering actuation and improve repeatability.
Design notes: the straight-arm form maintains consistent linkage geometry under torque, reducing mechanical lash and keeping the steering centred under dynamic loads. The 25T spline interface corresponds to common 25-tooth servo splines used across many MAXX setups, enabling direct-fit installation where a 25T mounting interface is required.
Installation and tuning role: assemble with the included stainless fasteners and verify screw lengths and thread engagement through the servo horn and servo saver stack. After installation, confirm correct linkage alignment and calibrate transmitter end points and centring to leverage the increased rigidity without introducing binding. In setup this component yields crisper steering inputs and improved feedback to the operator on mixed or rough surfaces.
Included items in the package are listed below for reference, use these parts when replacing the servo horn to retain correct mounting hardware and position within the servo area.
