Inner Suspension Arm Pins for Yokomo YOKSD009B  [YOKSD009B]

Replacement inner suspension pivot pins

The Yokomo YOKSD009B inner suspension arm pins are supplied as replacement pivot parts for RC inner suspension arms, intended to keep the arm secured at the chassis pivot. These pins perform the pivot function inside the arm assembly and support steady suspension geometry while the model is under load.

To fit the pin, line up the arm mounting hole with the chassis pivot and push the pin through so the arm rotates freely on the planned axis; then confirm there is no unwanted movement. As this component wears, check the pin and arm hole for ovalisation or wobble during routine maintenance and swap the pin when play begins to affect handling.

From a tuning standpoint, inner arm pins are part of the suspension baseline. Pins that are worn or loose introduce play that changes roll centre and steering response, whereas correctly seated pins help maintain suspension timing and consistent behaviour between sessions. When changing camber, toe, or roll stiffness make sure pins remain seated to avoid adding setup variance.
