2006-2010 Dodge Charger Underdrive Pulleys

Installing 2006-2010 Dodge Charger Underdrive Pulleys reduces the speed of accessories like the alternator, water pump, and power steering pump, freeing up horsepower that would otherwise drive these components. On the Charger, this typically gains a decent horsepower increase at the wheels, plus slightly better throttle response.

 

Before installing underdrive pulleys, make sure your alternator can still charge properly at idle with reduced pulley speed. If you have a lot of electrical accessories or a high-output stereo system, you might see voltage drop issues, especially during city driving.

 

Ordering the 2006-2010 Dodge Charger Engine alongside related components helps you handle everything in one pass instead of revisiting the same area later. That planning naturally extends to 2006-2010 Dodge Charger Intake Manifolds & Plenums, which are often addressed during the same stage of the build. Including 2006-2010 Dodge Charger Throttle Bodies at the same time keeps the process streamlined and avoids breaking the work into separate steps.
