GFB 3pc Lightweight Pulley Kit

Like all GFB lightweight pulleys, this one begins life as a single 6061 T6 aluminum 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 4.87lbs. 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 belt.
