GPM Racing Aluminium 7075 25T Servo Horn for Traxxas 1/10 4WD MAXX 1.0 Monster Truck-89076-4 (TXMS025T75)

Precision 7075 25T Servo Horn for TRAXXAS MAXX

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.

Packing includes

• Servo Horn – 1 pcs
• Stainless Steel Cap Head Screw 3×12 – 1 pcs
• Stainless Steel Round Head Screw 3×14 – 1 pcs

This item is compatible with

• TRAXXAS-1/10 MAXX MONSTER TRUCK-89076-4
• MAXX W/WIDEMAXX MONSTER TRUCK-89086-4

What spline count is required for this horn?

This horn is specified as a 25T unit and requires a servo with a matching 25-tooth spline. Verify spline count before attempting installation to ensure compatibility.

How should I check screw engagement?

Confirm the supplied screws thread fully without bottoming out and that there is secure engagement through the horn into the servo saver or servo output hub; replace with longer screws only when necessary.

What tuning changes are recommended after fitting?

After fitting, re-centre the servo, adjust travel endpoints and verify there is no binding across the full steering sweep to take advantage of the improved rigidity for cleaner steering response. Write Product Review Please sign in your account before you can write any review. Sign In Close
