For TRAXXAS TRX-4 25T Aluminium Servo Horn with Spring and Collar - TRX4025TA/3H by GPM  [TRX4025TA/3H]

25T Aluminium Servo Horn for TRX4 Trail Steering

This 25T aluminium horn is an RC replacement part compatible with TRAXXAS TRX4 platforms and listed as model TRX4025TA/3H. The unit features a machined arm with an embedded spring to reduce shock to the servo during impacts, plus three selectable holes to tune tie-rod placement for varied link configurations.

Notes on fitting: the spring assembly makes the horn thicker than standard plastic arms, so in the stock TRX-4 servo location you may need to reverse the support tie rod angle for adequate clearance. When fitted correctly the front reverse steering gear stays in its original location, but confirm tie-rod alignment before final assembly.

Manufacturer-supplied hardware includes the aluminium servo horn, stainless steel round head screws, an aluminium collar, and a 3mm metal washer to complete a single-arm steering upgrade.
