March Performance Late GM Power and Amp series pulleys are designed to give superb performance, while maintaining perfect electrical charging, even at idle. They create about 11 hp at the rear wheels by reducing accessory drag. These pulley kits are ideal for vehicles with high amperage needs, such as towing or heavy stop-and-go driving.
