Yokomo SD-414CA Aluminum Kingpin Collar for DP-series front knuckles  [SD-414CA]

Kingpin Collar for DP-series Front Knuckles

This SD-414CA kingpin collar is an anodized aluminum collar designed for RC-scale front knuckle assemblies, intended to sit above and below the front knuckle on the kingpin shaft to provide a stable bearing surface and consistent spacing.

Installation is straightforward: slide one collar onto the kingpin above the knuckle and one below, verify clearance so the knuckle rotates freely, and secure fasteners per your chassis manual. Check for binding after installation and make small adjustments to mounting hardware or shims to restore smooth steering motion.

Tuning role: the collars act as hardened seating points that reduce play at the kingpin interface and help maintain steering geometry under load, which can improve repeatability of steering feel and response when adjusting toe and caster settings.
