What is the benefit of a 15% overdrive pulley?

A 15% overdrive pulley spins the supercharger faster than the stock pulley. This increased speed generates more boost pressure, which can lead to a noticeable increase in horsepower and torque for your vehicle.

What material is this supercharger pulley made from?

This ATI supercharger pulley is constructed from durable aluminum. This material choice helps ensure it can withstand the rigors of high-performance engine operation.

Does this pulley come with a new serpentine belt?

This product is for the supercharger pulley only. A new, appropriately sized serpentine belt may be required for installation depending on your specific setup and is sold separately.
