Kyosho Motor Cycle Aluminium Servo Arm 25T & Steering Arm C8/C10 by GPM KM025TM26  [KM025TM26]

Aluminium servo & steering arm set

This GPM KM025TM26 two-piece set replaces standard plastic control arms on Kyosho motor cycle models with aluminium alternatives, providing a stiffer interface between the servo output spline and the steering linkage. The kit targets installations using a 25T servo spline and includes matched C8 and C10 style arm footprints commonly found on Kyosho motorcycle assemblies.

Installation is straightforward on typical Kyosho motorcycle setups: remove the stock arm, align the aluminium arm on the 25T servo spline, and secure using the existing retaining screw or hardware from the original arm. No special tools beyond the standard hex driver for the servo screw are required for routine replacement.

How this helps tuning: aluminium arms reduce flex under load compared with stock plastic parts, which can produce crisper steering input and more consistent steering centering during aggressive throttle or braking inputs on the model. They are intended as a hop-up focused on control feel rather than altering servo output or geometry.

Maintenance notes: inspect mounting screws and spline engagement periodically for wear, and retain any thread locker used on the original mounting hardware. Aluminium surfaces can be left bare or lightly protected with a corrosion inhibitor if the model is used in damp conditions.
