Aeromotive Alternator Overdrive Pulleys 21103

Aeromotive alternator overdrive pulleys are the great equalizers when used in conjunction with horsepower-boosting underdrive crank pulleys. Some drivers notice an unhealthy drop in charging capacity after installing underdrive pulleys. These natural CNC-machined finish overdrive pulleys resolve that issue by counteracting those slower underdrive revolutions. They're available in 32 and 50 percent overdrive versions. Alternatively, if you merely require increased charging capacity for that sweet sound system or other electronics, Aeromotive alternator overdrive pulleys save the day again!
