Vortech Superchargers 6-Rib 3.125" Drive Pulley (2A036-312)
3.125-Inch 6-Rib Drive Pulley for Vortech Centrifugal Superchargers
The Vortech Superchargers 6-Rib 3.125" Drive Pulley (PN 2A036-312) is a precision-machined supercharger pulley engineered for Vortech centrifugal supercharger systems utilizing a 6-rib belt drive. With its larger 3.125-inch diameter, this pulley reduces supercharger speed compared to smaller options, making it ideal for dialing in conservative boost levels, improving belt control, and enhancing long-term reliability.
Machined from 6061-T6 aluminum and finished with a durable hard anodized coating, this pulley features the correct rib profile to maximize belt surface contact for precise fitment and smooth, slip-resistant operation. Manufactured to SAE standards, it delivers consistent performance and durability for both street-driven and performance-oriented Vortech supercharger setups.

FAQs
- Will a larger pulley reduce boost?
Yes. A larger pulley diameter reduces supercharger speed, which typically lowers boost compared to smaller pulleys, depending on the overall setup. - Is tuning still required if boost is reduced?
Yes. Any change to supercharger pulley size can affect airflow and fueling, so proper tuning is always recommended.
