Products > Billet Alternator Pulleys

B&B's Aluminum Pulleys are intended for applications where engine speeds exceed those of the average passenger car. By reducing the parasitic drag brought on by turning belt driven accessories faster than designed,power is increased by driving accessories such as water pumps and alternators at correct RPM ranges. Reduction pulleys also prevent premature failure of accessories caused by increased RPM in race engines.

B&B Billet Aluminum Pulleys are machined from aircraft quality aluminum bar stock. Billet pulleys offer the most reliability under extreme racing conditions.
