This Arrowmax set contains ten blue 3x6x1mm aluminium shims intended for precise alignment and spacing tasks on RC models. They let you make measured tweaks without resorting to thicker washers.
These shims are handy for setting pinion and spur clearance, adjusting bearing endplay, or tuning linkage geometry. Their sizing is suitable for compact assemblies where fine control matters.
Aluminium keeps weight low and provides reliable stability under load, while the anodised surface reduces corrosion risk and helps you spot shim placement during servicing.
