Brass front mount paired with 25T aluminium horn

This 19 piece upgrade is crafted for the TRAXXAS TRX4 TRAIL CRAWLER platform and combines a brass front bumper mount with a 25T aluminium servo horn to reduce flex and improve steering consistency on technical lines.

The materials are stated in the product title: the brass mount adds nose weight and rigidity while the 25T aluminium horn gives a direct metal spline interface at the servo output. The items are designed to integrate with the TRX4 front assembly, assuming the spline and mounting geometry match TRX4 standards.

Installation and tuning: the brass mount provides a stiffer base than typical plastic components and the aluminium horn helps eliminate horn flex. Use this set when you want a firmer front-end anchoring solution and a precise servo arm shape for steering tweaks. Confirm spline count and clearance before final torqueing to ensure freedom of movement.

Do I need special tools to fit this set?

Basic hand tools, hex drivers and a torque driver for final tightening are sufficient. Use thread locker on metal-to-metal fasteners if you want extra security.

Will the added weight affect crawling performance?

Additional nose weight can improve traction on climbs but may alter balance; test on your usual trails and adjust battery or ballast as needed for preferred handling.

Is the 25T horn compatible with aftermarket servos?

Most hobby servos that use a 25T spline will accept this horn; if your servo uses a different spline count, you will need a matching horn or an adapter.

Should I change link lengths after installing the horn?

Changing horn geometry can alter steering throw. After install, centre the servo and check link positions; trim or move links to eliminate bump steer or excessive throw.
