Yokomo YOKSD009B Inner Suspension Arm Pins  [YOKSD009B]

Inner suspension arm pins for RC

The Yokomo YOKSD009B inner suspension arm pins are a replacement pivot component for RC inner suspension arms, designed to keep the arm mounted securely to the chassis pivot. These pins serve as the mechanical pivot point inside the arm assembly and play a straightforward role in maintaining consistent suspension geometry under load.

Installation is simple in concept: align the arm's mounting hole with the chassis pivot, insert the pin so the arm can rotate freely on the intended axis, and verify there is no excessive play. Because this is a basic wear item, check the pin and the arm hole for signs of elongation or wobble during routine maintenance and replace when movement affects handling.

For tuning, inner arm pins are part of the suspension's mechanical baseline. Worn or loose pins introduce unwanted play that changes roll centre and steering feel, while properly seated pins help preserve suspension timing and repeatability between runs. When adjusting camber, toe, or roll stiffness, confirm pins sit consistently to avoid introducing variability into setup changes.
