Brass front mount plus 25T aluminium servo horn set

This 19 piece upgrade set is specified for the TRAXXAS TRX4 TRAIL CRAWLER and combines a brass front bumper mount with a 25T aluminium servo horn to deliver a firmer mounting point and reduced horn flex for trail and crawl applications.

Materials are described in the product title: a brass mount to add rigidity and nose weight, and a 25T aluminium horn to give a solid metal interface at the servo spline. The parts are intended to fit the TRX4 front assembly where spline count and mounting geometry conform to TRX4 standards.

Fit and setup guidance: the brass mount supplies a more rigid base than usual plastic parts while the aluminium horn reduces compliance at the servo output. Use the set to improve steering precision or to test different horn geometries. Confirm spline compatibility and clearance before final installation to avoid restricting steering motion.

Is the set suitable for competition crawling?

Yes, it gives a firmer steering pivot and less horn flex, which can benefit precise inputs in competitive crawling, provided you maintain proper setup and clearances.

Do I need to re-centre my servo after fitting?

Always centre the servo before tightening the horn to ensure neutral steering and to avoid introducing offset or binding into the steering geometry.

Will this change my steering ratio?

Switching horn radii or positions can change effective steering ratio; check horn position and link lengths after install and adjust trim or link placement as required.

Any maintenance advice for metal upgrades?

Periodically inspect fasteners for loosening, check mating surfaces for wear and clear debris after runs to keep metal parts operating smoothly.
