Engineered 7075 23T Servo Horn for Crawling

The TRX4023TC servo horn is an aftermarket CNC-grade aluminium arm intended to upgrade TRAXXAS-style steering linkages for demanding trail use. Machined from 7075 material to tight tolerances, the straight single-arm profile increases stiffness and repeatability compared with moulded plastic arms while retaining the common 23T spline interface.

The dual tie-rod hole layout provides discrete adjustments to effective lever length at the servo, enabling precise steering calibration and toe control without modifying axle links. Supplied stainless steel round head screws match the mounting points shown in the product listing for secure attachment to the servo and tie rod end.

Installation: align spline teeth with the servo output, select the tie-rod position that achieves desired steering geometry, and torque fasteners to a conservative value to protect plastic servo casings. This component is intended for RC-scale crawlers and is focused on improved steering accuracy and linkage geometry on compatible TRAXXAS platforms.

What tolerances should be expected from the machined arm?

The arm is CNC machined from 7075 aluminium to provide consistent spline engagement and minimal runout, improving repeatable steering input under load.

How does hole placement affect steering geometry?

Changing the tie-rod mounting hole alters the lever arm at the servo, allowing measured shifts in mechanical advantage that affect steering throw and centring characteristics.

Are the supplied screws suitable for power servos?

Stainless steel round head screws are supplied for secure mounting; when using high torque servos verify thread engagement and consider using threadlocker or metal servo cases to prevent stripping.
