TRX-4 25T Aluminium Servo Horn Spring-Loaded for Trail Crawling - TRX4025TA/4H by GPM  [TRX4025TA/4H]

25T Aluminium Servo Horn with Internal Shock Spring

This 25T aluminium servo horn is a scale upgrade for TRX-4 style trail crawlers, made to sharpen steering response while adding a degree of impact compliance. The stainless spring inside the horn absorbs sudden loads to protect servo internals, and extra tie rod holes let you tweak steering throw and toe without changing the servo arm length.

The kit contents are: servo horn (1 pc), stainless steel round head screw 3x12 (2 pcs), aluminum collar (1 pc), and 3mm metal washer (1 pc). These components are supplied to match TRX-4 compatible servo splines and mounting patterns.

Fit advice for TRX-4 vehicles: because of the added spring, the horn has a deeper profile that can reduce clearance in factory servo positions. When installed in the stock location, reversing the support tie rod angle typically restores clearance and keeps the front reverse steering configuration unchanged. Confirm spline seating and link geometry before final fastening.

Performance notes: the built-in spring introduces controlled give that helps mitigate shock to the steering system, and the multiple mounting holes allow on-the-fly adjustments to steering geometry. Ideal for drivers seeking a smoother steering feel on tricky terrain and scale obstacles.
