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 billet 6061-T6 aluminum. This is the same material March uses for their NASCAR pulleys! These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. March goes as far as hard coating the high wear areas on their high water flow ratio pulleys! Their street rod ratio increases water flow and fan speed, which helps at critical low speed driving. All pulleys have a maintenance-free clear powdercoat.
March Performance's Ultra kit is designed to fit 1965-1969 289/302 engines with: A 3-bolt crank pulley; a passenger-side lower radiator hose standard-rotation water pump; air conditioning.
