This is GNP's Lightweight Pulley Combo
Now that we have produced two lightweight pulleys that work very well together for your Subaru by reducing rotational mass only. It's time to offer them together at a discounted price of course.
What these lightweight pulleys do is remove rotational mass from your motor, allowing it (and you), to accelerate quicker. These are not underdriven pulleys, you can use the stock belts.
GNP's lightweight crank and alternator pulleys have been CAD designed and CNC milled out of T6061 aluminum then anodized for a great finish. All of GNP's lightweight crank pulleys also get dynamically balanced to 8200 RPM to ensure problem free running.
Available in 3 colours Red, Blue and Black.
What the combo is:
1-GNP's lightweight crank pulley
1-GNP's lightweight alternator pulley
