This Yokomo YOKZCRA3605 collar is a compact shim designed for general R/C use, supplied as a pack of 8 pcs in red. Its 3x6x0.5mm profile is primarily intended where thin, repeatable spacing is required in small assemblies.
Typical uses include shimming shafts, adjusting wheel or bearing endplay and fine-tuning component alignment during setup or maintenance. The collar can be stacked to reach incremental thicknesses for micro-adjustment without changing larger parts.
Installation is straightforward: slide the collar onto the shaft or into the bore where spacing is needed, verify axial play and secure adjacent components as per your chassis build. Keep spares on hand for iterative tuning when you change gear ratios, bearings or wheel hubs.
