GPM Racing 7075 Alloy 25T Servo Horn for Pd Racing 1/10 TK10 V3 EXB 4x4 Brushless RC Car (TK3025TSH)

TK3025TSH 7075-T6 25T Servo Horn Overview

The TK3025TSH is a 25-tooth servo horn made from 7075-T6 aluminium for PD RACING TK10 V3 EXB steering linkages. The straight-arm geometry yields a direct connection between the servo spline and tie rods to support responsive steering inputs.

Important attributes include a 7075-T6 construction for stronger wear resistance, two tie-rod mounting options to alter leverage and steering throw, plus an integrated spring feature to moderate impact loads and reduce shock transfer to the servo gears. It serves as a direct replacement for factory code PD861-041 in compatible installations.

Installation uses standard 25T spline procedures: slide onto the spline, tighten the supplied screw, and set the tie-rod position to achieve the required steering geometry. Apply a medium-strength threadlocker on the mounting screws to help prevent loosening during operation.

This CNC 7075 25T horn is aimed at modelers seeking improved steering durability and adjustable leverage on the TK10 V3 EXB platform while adding mechanical protection for the servo assembly.

What spline count is required for fitment?

A 25-tooth servo spline is required. Confirm your servo uses this spline count prior to fitting the horn.

Can the spring reduce servo damage?

Yes. The built-in spring offers limited compliance that absorbs some impact energy, reducing the magnitude of shocks reaching the servo internals.

Is it supplied with installation hardware?

The horn is supplied with the mounting screw required for installation; inspect the pack and use threadlocker on the screw for secure fastening.

How should I choose between the two tie-rod holes?

Select the position to alter the tie-rod radius: an outer hole increases steering throw, while an inner hole reduces throw and raises mechanical advantage.

Does 7075-T6 require special care?

Routine inspection for wear and keeping the spline area free from grit will help maintain performance; avoid prolonged exposure to corrosive conditions to preserve the alloy finish. Write Product Review Please sign in your account before you can write any review. Sign In Close
