March Performance Small Block Chevy Ultra Serpentine Conversion Kits

March Performance small block Chevy Ultra serpentine conversion kits will make it easy to convert your old V-belt pulleys. They bolt to the front of any 1969 or later small block Chevy heads and are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. The included bracket kits come complete with stainless steel tensioning rods and chromoly rod ends for high performance operation. Required mounting hardware is included and is powdercoated to eliminate polishing in those hard-to-reach places. Matching serpentine pulleys are precision CNC-machined from 6061 T-6 aluminum. These pulleys will not fracture like common cast pulleys because they are hard coated in the high-wear areas on their high water flow ratio pulleys. The street rod ratio increases water flow and fan speed. This helps at critical low-speed driving. Show Less
