GPM Racing Alloy 6061-T6 Original 25T Servo Horn for Traxxas 1/10 4WD MAXX 1.0 Monster Truck-89076-4 (TXMS025T)

Precision 25T Servo Horn for TRAXXAS MAXX

Engineered as an aftermarket replacement for the TRAXXAS MAXX servo area, this 25T horn is CNC machined from 6061 T6 aluminium to minimise rotating mass while preserving yield strength under load. The design focuses on dimensional accuracy and consistent spline engagement to support predictable steering inputs.

Compatibility targets standard 25T spline hubs for direct fitment, and the product ships with stainless steel mounting screws to ensure consistent clamping. From a tuning perspective, the increased stiffness and lower inertia translate to improved repeatability and crisper steering response when paired with appropriate servo calibration and linkage geometry.

Packing includes

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

This item is compatible with

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

What machining tolerances are relevant for fit?

The CNC process maintains tight spline and hole tolerances to ensure accurate engagement with 25T servo splines and correct alignment of mounting hardware.

How does material choice affect dynamic response?

6061 T6 provides a higher modulus than typical plastics, reducing flex and rotational inertia at the horn which helps deliver a more consistent mechanical response under repeated inputs.

Recommended installation notes?

Seats should be clean, spline engagement verified, and screws torqued to appropriate hand-tight plus small fraction; consider threadlocker if running in high-vibration environments. Write Product Review Please sign in your account before you can write any review. Sign In Close
