Description:
ATI Super Pulley clutch hub assemblies eliminate belt failures, can increase boost, and reduce wear of your supercharger. That's probably why they're "Super"!

Features and benefits include:

* Designed for large displacement superchargers and high-horsepower race engines
* Accommodates bolt-on pulleys as small as 50 teeth by 8mm HTD
* ATI Superior Sprag Technology releases the blower whenever it's spinning faster than engine rpm—virtually eliminating belt failures
* More boost between shifts, as the blower will not pull down as fast as the engine rpm during the gear change
* Reduces supercharger wear by not allowing the gear drive to mesh in the opposite direction when spinning down
