Factory Pro Black 5mm Collar Set (0.5, 1 & 2mm, 5pcs Each) Precision Shim Pack  [FP-M-ACS501BK]

Compact Shim Kit for Accurate RC Shimming

The Factory Pro Black 5mm Collar Set (0.5, 1 & 2mm, 5pcs Each) contains collars in 0.5mm, 1mm and 2mm thicknesses and provides five pieces of each size for reliable spacing work. This compact set helps hobbyists make small, repeatable adjustments to components where 5mm diameter spacers are needed.

Where These Collars Work Best

These collars are built for general RC use and suit a variety of tasks like keeping correct spacing in suspension mounts or securing gears and bearings. The black finish aids visual identification during quick setup changes and keeps parts looking tidy in the pit box.

Best Practices for Setup

Try stacking different thicknesses to dial in clearances without resorting to permanent modifications. Using combinations of 0.5mm, 1mm and 2mm collars makes it easier to experiment with ride height and drivetrain play while maintaining solid assembly integrity.
