  • Sale
  • Regular price $335.45


GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminum and offer faster acceleration through significant weight reduction on the crankshaft.

The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev. Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. I

t should be noted that our underdrive pulley kits do NOT adversely affect the operation of the accessories. If they did, we would not sell them!

Features:

* Improved throttle response and acceleration through significant reduction of rotating mass

* Engine feels more free-revving

* Under-driven kits offer more power through reduction of parasitic losses from the accessories with NO adverse affects on their operation
