One of the easiest ways to pump up the power of your Zl1 is to increase the factory boost level. When it comes to aftermarket pulley technology, there is no better choice than Metco. Metco design engineers considered the engine's rpm capability, durability and other unique features to create the ultimate choice in aftermarket blower pulleys.

Metco offers 3 options for you to choose from: 2.85″, 2.50″, and 2.40″. This simple replacement pulley gives the illusion of a factory stock diameter pulley to the untrained eye; but if you know cars, you will understand the powerful capabilities of this pulley.

Important:

In order to change your supercharger pulley on the LSA engine, the original and new pulley must be installed with using a press or a suitable pulley tool.
