What is the main benefit of an aluminum crank pulley?

Aluminum crank pulleys are lighter than stock steel or cast iron pulleys. This reduction in rotational mass can lead to a slightly improved engine response and acceleration.

What does the 7-groove design mean?

The 7-groove design refers to the number of channels on the pulley's surface where the drive belts sit. This provides more contact points for the belts, ensuring a more secure and stable drive for your accessories.

Is this pulley a direct replacement for the stock Nissan GT-R pulley?

Yes, this ATI crank pulley is designed to be a direct-fit replacement. It is intended to install in the factory location using the original mounting hardware and alignment.
