Precision milled high strength stainless steel and guaranteed to be flat and burr free (do not be fooled by cheaply priced micro shims as they're often out of spec, not flat, made with inferior materials, and will cause bearing damage and systems failure!)

-Use to remove slop from driveshaft input/outputs, axle shafts between the pin and output bearing, and transmission/diff casings.

-Suitable for use in all surface and air applications, electric or nitro powered.

-Stands up well to long term vibration, great for drone and helicopter applications.
