Cut for reverse (counter rotating or pusher) prop. Light weight design made of high quality aluminum bar stock. Polished to mirror finish. Comes with 2.3, 3.2 and 4mm collets.
ProSpin spinners are made from high quality bar-stock 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.
Shiny Finish styles are considered "while supplies last", new style is brushed aluminum.
