These 5 mm hole split collets fit all the GM spinners we sell. They are suitable for motors/gearboxes with 5 mm diameter shafts.
The included 8 mm front cone retaining screw is suitable for 28 mm, 30 mm and 32 mm diameter spinner cones. A 16 mm GM Cone Retaining Screw will be required for 38 mm spinners if the original one is no longer available.
Use to replace the original split collect so the spinner can be used with a different sized motor/gearbox shaft.
