ProSpin spinners are made from high quality barstock for strength. They won't crack like cheap cast aluminum spinners do.
ProSpin spinners are also 30% lighter than cast aluminum.
All spinners include a shaft bushing, prop nut, and bolt.
All spinners are polished to a mirror shine finish as pictured above.
