Yokomo YOKZC206C 3mm Aluminum Collar for R/C Drivetrains  [YOKZC206C]

3mm aluminum spacer for precise shaft alignment

The Yokomo YOKZC206C 3mm aluminum collar is a general-purpose R/C spacer that creates consistent axial separation between bearings, gears and other rotating parts, reducing lateral play and improving repeatable assemblies.

Fitment is simple: place the collar where axial clearance must be controlled, then secure the surrounding hardware using the model's existing screws, set screws or retaining components. The collar functions as a passive spacer and does not replace the model's original fastening method.

For setup work, employ the collar to make measured adjustments to gear mesh and bearing preload without re-machining or stacking shims; it gives a consistent gap for setup checks or on-event tuning of electric scale cars.
