The Yokomo R12-12U is a direct replacement front upper suspension arm pin designed for the R12 and GT series chassis. As a small but critical link point in the front suspension, this pin locates the upper arm and contributes to roll centre and camber behaviour when setting up the model.
Installers will find the pin useful when replacing worn parts or when changing geometry during tuning; the pin function is straightforward and requires basic wheel removal and linkage access. Maintain clean mating surfaces and check fit to avoid play in the arm mount.
