The Yokomo ZC-A3660B offers single-piece aluminum spacers as a more stable alternative to stacking thin shims. The thicker construction reduces movement between layers and improves repeatability of component spacing.
The kit contains 4mm, 5mm and 6mm spacers, eight pieces of each size per pack. These spacers are intended for precise spacing adjustments such as gearmesh, suspension pickup spacing and axle or hub offsets on 1/10 touring and drift platforms. Installation replaces stacked thin washers with a single spacer of the appropriate thickness at the same fixing point.
When setting up, choose the spacer thickness that meets the required clearance or preload, then verify alignment and rotation after tightening to ensure no unintended preload has been introduced. Compared with paper or multiple thin metal shims, aluminum spacers deliver improved stiffness and predictable fit.
