This product is a set of thin precision shims sized 14 mm outer diameter by 10 mm inner diameter and 0.2 mm thickness, supplied in a pack of eight. These shims are used in radio‑controlled vehicles and other hobby applications to adjust spacing, preload, or alignment between components such as bearings, gears, or suspension parts. They help fine‑tune clearances to ensure smooth operation and optimal performance. The shims are made from durable material that resists deformation during installation.
