Koswork 3x8x0.5mm 3mm Steel Black RC Washer - KOS40308-05

The Koswork KOS40308-05 is a 3x8x0.5mm steel washer and shim set designed for use in RC cars and buggies where precise spacing and shimming are required. Each washer has a 3mm inner diameter, 8mm outer diameter, and a 0.5mm thickness, making them well-suited for adjusting bearing preload, differentials, gear mesh, and suspension pivot points. The black steel construction keeps them durable under the loads typical of RC car drivetrains and suspension assemblies.
