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

Precision shim for accurate spacing

This Yokomo aluminum shim is a compact, precision 3x8x0.5mm spacer for scale RC use, sold under model YOKZCA3805B. The 0.5mm black-anodized aluminum washer offers controlled spacing where small changes affect handling, drivetrain alignment, or bearing preload.

Fitting is simple: place the shim between mating parts such as wheel hubs, bearings, or gear collars to reduce lateral play or to achieve the exact stack height required. When stacking shims, confirm total thickness and clearance before final assembly to avoid binding on shafts or interference with rotating parts.

For setup work, this shim gives repeatable, fine increments of spacing without on-site fabrication. It is supplied as an RC-scale accessory suitable for general shimming tasks in electric and nitro model setups and should be treated as a small replacement part during maintenance.
