TRX-4 Aftermarket 23T Servo Horn 6061 Aluminum Spring Buffer 4-Position TRX4023TA/4 TRX4023TA/4H by GPM  [TRX4023TA/4H]

23T 6061 T6 servo horn for TRX-4

Built as an aftermarket steering arm for TRAXXAS TRX4 style trucks, this servo horn is aimed at improving steering precision while integrating a spring-loaded shock buffer at the servo spline. Machined from 6061 T6 aluminum, the straight arm shape enhances rigidity while keeping weight controlled.

The internal spring helps protect the servo by absorbing peak forces, and the four tie-rod holes allow lateral movement of the linkage to fine tune steering ratio and roll centre. Because the spring adds thickness, inspect clearance in the TRX-4 servo location; certain stock layouts may need the support tie rods reversed to prevent contact with the horn.

The supplied parts include the servo horn, stainless mounting screws, an aluminum collar and a 3mm metal washer for assembly. Use the multiple holes to dial in handling and always verify mechanical clearance before final tightening.
