This 85-91 C4 Corvette Air Pump Pulley Kit has highly polished aluminum brackets and uses grade 8 bolts for a secure hold and superior strength. A great item to help get those horses to the rear tires, while allowing the engine to rev even quicker than it does from the factory.
Purchase of new belt locally is required in some installations due to varying pulley sizes installed by GM according to option requirements.
