Front Knuckle Kingpin Collar for DP-series - Yokomo SD-414CA  [SD-414CA]

What the DP-series Kingpin Collar Does

The SD-414CA collar is made from anodized aluminum and fits on the kingpin above and below the front knuckle to provide a consistent bearing surface and correct spacing during steering operation.

Fitting is done by sliding a collar onto the kingpin above the knuckle and another below, then confirming there is no binding before fastening. If steering binds, adjust shimming or retorque components until smooth rotation is achieved across the steering travel.

Benefit for setup: the collars reduce movement at the kingpin seat and help preserve steering geometry under load, which can lead to more reliable steering feedback when dialing in toe and caster changes.
