20725 - March Chevy Small Block Performance Serpentine Kits

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. Powder coated 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 used for NASCAR pulleys. These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. They went as far as hard coating the high wear areas to 65 Rockwell (harder than steel). Their street rods ratio increases water flow and fan speed. This helps at critical low speed driving. All pulleys have a maintenance free clear powder coat.

Fits most cars. Requires 13" clearance from center of water pump shaft to hood. Works best with 1969 or later heads, 1969-1984 heads require tapping one hole in passenger side head, later heads simply bolt on. Will work with Vortech heads. If using ZZ4 style timing cover you will have to modify short water pump for clearance.
