Yokomo YOKZCA3805B - Aluminum Shim 3x8x0.5mm Black  [YOKZCA3805B]

Aluminum shim for tuning

This Yokomo aluminum shim is a small, precision 3x8x0.5mm spacer intended for scale RC use only, sold under model YOKZCA3805B. The part is a thin 0.5mm black-anodized aluminum washer designed to provide controlled spacing where small adjustments affect handling, drivetrain alignment, or bearing preload.

Installation is straightforward: place the shim between mating parts such as wheel hubs, bearings, or gear collars to reduce lateral play or to obtain the exact stack height required. When stacking multiple shims, verify total thickness and clearance before final assembly to avoid binding on shafts or interfering with rotating parts.

For tuning purposes, this shim is useful when you need repeatable, fine increments of spacing without fabricating shims on-site. It is sold as an RC-scale accessory, suitable for general shimming tasks in electric and nitro model setups, and should be handled as a small replacement part during maintenance and setup.
