2005-2013 C6 Corvette Underdrive Pulleys

Crankshaft accessories fall under 2005-2013 C6 Corvette Underdrive Pulleys that reduce parasitic 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.

 

The alternator and water pump rob way more horsepower than people realize because they're spinning constantly at crank speed, which is why slowing them with underdrive pulleys frees up immediate power that you can feel. Stacking that with cold air from 2005-2013 C6 Corvette Cold Air Intakes adds even more on top, then if you're going deeper, better manifolds at 2005-2013 C6 Corvette Intake Manifolds & Plenums improve flow all the way to the heads, or just browse everything possible at 2005-2013 C6 Corvette Engine.
