Yokomo B9-414CSA kingpin sleeve set for BD/MDR/MRTC/MSR/RSR compatible chassis  [B9-414CSA]

Kingpin sleeve for tuning and identification

This color variant serves as a kingpin sleeve for RC-scale cars and is supplied as a set of 2 pcs. The part is intended for use on compatible touring and competition chassis where a sleeve is fitted over the kingpin to provide spacing and a visible marker for setup adjustments.

Role in setup: the sleeve functions as a spacer/insulator on the kingpin assembly to help set caster and camber behavior without changing the kingpin itself, and its color-coding helps you keep multiple setup options organised trackside. It is sold as a simple replacement/up‑grade accessory for maintenance and small changes in steering geometry.
