GFB Lightweight Pulleys

0 Star Rating

Buy in bulk and save


Like all GFB lightweight pulleys, this one begins life as a single 6061 T6 aluminium alloy billet, and is then precision CNC machined to exacting tolerances. GFB then anodizes it black for a stealthy appearance and superior wear resistance. 

This results in a large saving of 4.87 lbs. of rotating mass over the factory pulleys, without sacrificing strength or reliability. Like all GFB lightweight pulleys, you can feel the improvements: 

* Sharper throttle response. 
* Crisper acceleration through each gear. 
* Retains the use of OE. 

Weight Comparison Between Stock and the GFB Lightweight Pulley. 

* Factory Crank Pulley - 4.89 lbs. 
* GFB Crank Pulley - 0.75 lbs. 

* Factory Water Pump Pulley - 1 lb. 
* GFB Water Pump Pulley - 0.53 lb. 

* Factory Alternator Pulley - 0.44 lb. 
* GFB Alternator Pulley - 0.18 lb. 

* Weight Savings vs. Stock = 4.87 lbs.!
