Model A Ford transmission to Hyper 9 adapter


This is a bolt in adapter for the Hyper 9 motor to the Model A Ford stock transmission.  This adapter utilizes the stock mounting locations and requires no modifications to the transmission or chassis to mount the motor.

This is a direct couple, meaning the clutch is eliminated.

While the stock transmission works, we do recommend an upgraded transmission such as the Mitchell overdrive to provide quieter operation.
