When the fans are mounted in the nose of the car, spacers are required to extend the shaft and position the fan closer to the radiator.
These spacers include the necessary hardware to mount to the motor shaft and fasten the fan to the spacer. The included hardware will clamp the fan to the spacer and help alleviate fatigue failure of the fan hub.
A typical installation will require two spacers – sold individually. Machined with a 1/4-20UNC thread to accept fan shaft bolt and a 5/16″ diameter for motor shaft. Contact us if you need a different size.
