Swap out the factory resin horn on your YD-2 Slide Rack for the Yokomo Y2-204323A 23mm aluminium servo horn to gain improved stiffness and tactile feedback. The metal construction smooths out deflection under load, making steering inputs more predictable when running 23T spline servos such as Sanwa or KO.
Aluminium offers a better strength to weight balance than resin, giving you steadier tracking and finer control at speed. The 23mm arm length is chosen to balance leverage and servo travel, helping drivers maintain precise lines without excessive servo movement.
Designed for 23T spline shafts, this horn works with popular servo models from Sanwa and KO. Installation is quick for most hobbyists using basic RC tools, and you should notice tighter steering and faster recovery in corner exits after the upgrade.
