March Performance Serpentine Alternator Drive Kit Ford 5.0L with Electric Water Pump Includes:

Precision machined from solid billet aluminum to fit perfectly and handle high torque and vibration. These drive kits come complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. Each kit has been powdercoated to eliminate polishing in those hard to reach places. Matching serpentine pulleys are precision CNC machined from 6061-T6 aluminum. This is the same material we use for NASCAR pulleys! These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. We go as far as hard coating the high wear areas of the pulleys.
