Pulley materials include aluminum being standard or steel providing durability. Underdrive percentages vary with 10 percent being mild or 25 percent offering maximum gains during racing.

 

Underdrive pulleys help you free up a few extra horsepower by slowing down accessories like the alternator and water pump so they aren’t being over-driven and stealing power from the wheels. While the gains are smaller than major mods, they add up when you’re chasing every bit of performance, and lightweight pulleys also reduce rotating mass so the engine revs more quickly. If you’re stacking mods, cold air options from 2014-2019 C7 Corvette Cold Air Intakes deliver more noticeable power gains, supercharger kits at 2014-2019 C7 Corvette Supercharger Kits & Accessories unlock massive increases, and the complete engine catalog at 2014-2019 C7 Corvette Engine lays out every available option.
