ATI Super Pulley Clutch Hub Assemblies

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
