Power Feeder Hub Sizing Chart
Every Super Feed hub and composite core, with the dimensions WRC machines them to. Measure your feeder against these before ordering a tire or a hub.

- Ø is a diameter. Bolt spacing is the distance between the two drive-pin holes, measured center to center.
- PSFH-9 is dimensioned on the catalog page by its bolt spacing and outside diameter only; call us with your feeder model for the bore.
