Yokomo YOKZC206C 3mm Collar - Drivetrain Spacer  [YOKZC206C]

3mm spacer for gear and bearing gaps

The Yokomo YOKZC206C 3mm collar functions as a spacer in scale R/C drivetrains, maintaining even axial distances between bearings, gears and other rotating components to reduce lateral play and aid repeatable builds.

To use, locate the collar at the desired axial position and then secure the surrounding elements with the model's original screws or retaining parts. The collar does not act as a primary fastener; it depends on the vehicle's existing hardware for final fixation.

For tuning, the collar enables incremental adjustments to gear mesh and bearing preload without modifying parts or stacking shims, which helps when evaluating different setup options.
