Inner Suspension Arm Pivot Pins - Yokomo YOKSD009B  [YOKSD009B]

Inner suspension pivot pins explained

The Yokomo YOKSD009B inner suspension arm pins serve as replacement pivot parts for RC inner suspension arms, keeping the arm secured at the chassis pivot. They form the mechanical pivot inside the arm assembly and contribute to reliable suspension geometry while the car is in use.

To fit, align the arm hole with the chassis pivot and insert the pin so the arm rotates freely on the intended axis, then verify there is no excessive play. Being a standard wear component, inspect the pin and the arm bore for elongation or wobble during routine checks and replace when handling becomes affected.

In setup work, inner arm pins are part of the baseline mechanical geometry. Excessive play from worn pins changes roll centre and steering characteristics, whereas properly seated pins help preserve suspension timing and consistent behaviour between runs. Always confirm pins are seated evenly when adjusting camber, toe, or roll stiffness to prevent setup drift.
