Koswork 10x12x0.1mm & 10x12x0.25mm RC Shim Set - KOS41012

The Koswork KOS41012 shim set provides precision 10x12mm shims in two thicknesses — 0.1mm and 0.25mm — for fine-tuning suspension geometry, diff preload, and bearing spacing on RC cars. Having both thicknesses in one pack gives you the flexibility to dial in exact tolerances without running multiple separate orders. These are the kind of small parts that make a real difference when you're chasing consistent setup across a race day.

Key Features

• Two thicknesses included: 0.1mm for micro adjustments and 0.25mm for larger spacing corrections
• 4 pieces of each thickness supplied, giving you 8 shims in total
• 10x12mm inner/outer diameter suits a wide range of 1/10 and 1/8 scale RC car applications
• Useful for setting bearing preload, shimming diffs, and correcting end-float on drivetrain components
• Compact and lightweight — worth keeping in your pit box as standard spares
