1997-2004 C5 Corvette Underdrive Pulleys

Crankshaft accessories fall under 1997-2004 C5 Corvette Underdrive Pulleys that reduce drag on your Corvette. Lightweight versions decrease rotational mass while underdrive ratios slow accessories during operation.

 

Pulley materials include aluminum being light or steel providing durability. Reduction percentages vary with 10-percent being mild or 25-percent offering maximum gains during high-RPM use.

 

Underdrive pulleys unlock hidden horsepower by slowing accessories like the alternator and water pump that constantly pull power from the crank. By reducing that parasitic drag, your engine can rev more freely and put more energy where it belongs. To keep building power the right way, you can explore all supporting upgrades in the 1997-2004 C5 Corvette Engine section, add airflow with 1997-2004 C5 Corvette Cold Air Intakes, and sharpen throttle response using 1997-2004 C5 Corvette Throttle Bodies.
