TRX-4 23T 6061 T6 Aluminum Servo Horn with Built-in Spring (4 Position Holes) TRX4023TA/4 TRX4023TA/4H by GPM  [TRX4023TA/4H]

23T aluminum servo arm for TRX4 steering setups

This aftermarket servo horn is designed for TRAXXAS TRX4 compatible rigs and provides a firmer steering response while incorporating a coil spring to absorb shock inputs between the horn and the servo spline. The straight-arm profile is machined from 6061 T6 aluminum to keep weight low while improving stiffness under steering load.

The integrated spring cushions abrupt impacts to help protect the steering gear, and the four tie-rod holes let you alter lateral attachment for fine tuning steering ratio and roll centre. The spring assembly increases local thickness, so confirm clearance in the factory servo location; some TRX-4 layouts require reversing the support tie rods to avoid interference with the reverse steering gear.

The kit ships with the main mounting components needed for installation: the aluminum horn, stainless steel mounting screws, an aluminum collar, and a 3mm metal washer. Use the positioning holes to adjust toe and steering sensitivity, and check mechanical clearance after any geometry change before final assembly.
