March Performance Series Serpentine Underdrive Pulley Kit for 289/302 engines with a standard rotation water pump.
Precision CNC machined from solid billet 6061-T6 aluminum to fit perfectly and handle high torque and vibration. This bracket kit comes complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. All necessary hardware included. 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 to "65" Rockwell (harder than steel)!
