Tamiya TT02B Hi-torque Aluminium Servo Horn 25T with Steel Tie Rod TT2B025STM by GPM  [TT2B025STM]

Durable 25T Servo Horn Upgrade for TT02B

This aftermarket aluminium 25T servo horn plus steel tie rod is intended for Tamiya TT02B 1/10 scale RC cars and supplied as one set. The aluminium arm replaces the OEM plastic horn and the steel tie rod lowers flex at the servo linkage to keep steering responses more predictable during cornering and chassis adjustments.

Fitment depends on a matching 25T servo spline and the TT02B steering geometry, so verify spline engagement and check for clearance before finalising the install. To fit, remove the original horn, mount the aluminium 25T arm onto the servo spline, secure with the original hardware, then connect and adjust the steel tie rod to set neutral toe and steering range. Take care not to over-tighten screws to avoid stripping the servo spline.

In tuning scenarios this component is chosen to sharpen steering feedback and reduce play between the servo and linkage, useful when changing steering rates or refining toe and Ackermann settings on the TT02B chassis.
