ATI Pulley - Drive - 3.74 - Alum - 31th HTD 8mm Drive - for 916430M Hub Behind Damper

This ATI 3.74-inch aluminum crank pulley features a 31-tooth HTD 8mm drive, specifically designed to work with the 916430M hub located behind the damper. It's a well-built component aimed at enhancing your engine's performance by altering its rotational characteristics.

Crafted from aluminum, this pulley is lighter than a stock steel unit, which can help reduce rotational mass. The 31-tooth HTD 8mm drive system is chosen for its ability to handle specific power transfer needs, making it a solid option for those looking to fine-tune their engine's setup. It's designed to fit directly onto the 916430M hub, simplifying the installation process for mechanics familiar with this type of component.

When considering a pulley upgrade like this, it's important to understand how it affects your engine's power band. A smaller or differently geared pulley can change the effective gear ratio for accessories or the supercharger, potentially leading to improved throttle response or increased boost pressure, depending on the application. This ATI pulley is a popular choice for builders looking for precise control over their engine's accessories and power delivery.
