Performance Machine forged aluminum pulleys are a favorite of the custom builder and enthusiast since long. Its finely machined surface perfectly mirrors the pattern of the PM wheels behind it for a complete custom look. They also feature Hard Anodized teeth for longer wear. All these PM pulleys are drilled 5 x 7/16" x 3 1/4" and work with stock wheels as well as PM wheels with 5-hole hubs. However, use with an OEM Harley wheel does not guarantee alignment with the wheel design pattern.
