Here, you are looking at the Go Fast Bits Lightweight Pulley Kit. This pulley kit has been designed using lightweight aluminum alloy materials which will help remove some of the rotational mass associated with the factory alternator pulley. The result is a sharper throttle response with easier revving. 

 

DETAILS:

• 6061-T6 aircraft-grade aluminum construction
• Includes crank, alternator, and water pump pulleys
• Removes rotational mass for faster revs
• Black finish

 

WEIGHT SAVINGS:

• Stock Crank Pulley: 4.89lb
• GFB Crank Pulley:.75lb
• Stock Water Pump Pulley: 1lb
• GFB Water Pump Pulley: .53lb
• Stock Alternator Pulley: .44lb
• GFB Alternator Pulley: .18lb

That is almost 5lbs of rotational mass lost.
