Light weight design made of high quality aluminum bar stock. Polished to mirror finish. Comes with 3.2 (1/8"), 4mm, and 5mm collets. Reverse Pitch Version.
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.
Notes on Ordering:
1. Find out the size of the prop nut you need.
2. If you need a different prop nut, you need to order it separately.
3. Some engines, i.e. Saito engines, require a bushing that is larger than the nut.
