Precision Inner Suspension Arm Pins - Yokomo YOKSD009B  [YOKSD009B]

Precision inner arm pins for chassis pivots

The Yokomo YOKSD009B inner suspension arm pins replace the pivot component in inner suspension arms, keeping the arm fixed to the chassis pivot point. These pins provide the central mechanical pivot inside the arm assembly and are important for steady suspension geometry under load.

Fitting is simple: match the arm mounting hole with the chassis pivot, insert the pin so the arm rotates on the intended axis, and ensure there is no excess play. As a replaceable wear item, inspect the pins and the arm holes regularly and change them if elongation or wobble appears during service checks.

When tuning, consider inner arm pins part of the mechanical baseline. Play from worn or loose pins alters roll centre and steering feel, while well seated pins preserve repeatable suspension timing. Verify pins are correctly seated whenever you make camber, toe, or roll stiffness adjustments to avoid inconsistent results.
