Sonnax flanged impeller hub FD-90-65G for late 5R110W converters has a large, reinforced flange with superior weld characteristics and a piloting diameter for accurate alignment. These features are especially important, as many of these converters have been rebuilt several times over and the material where the impeller hub mounts may be so thin that it becomes difficult to weld a non-flanged impeller hub. The large flange also provides a substantial thrust bearing mating surface.

• Substantial flange with superior weld characteristics
• Piloting diameter for accurate alignment
