March Ford 289-302, 351W Ultra Serpentine Drive Kits replace your low performance V-belts, pulleys, and brackets and eliminate any issues with belt throwing. This drive kit comes complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. All necessary hardware included. The "Ultra" kits feature sculpted Futura mounting brackets that are precision CNC-machined from solid billet 6061-T6 aluminum to fit perfectly as well as handle high torque and vibration.
The high tensile strength of the material combined with the hard coating on all high wear areas means a much longer duty life than common cast pulleys with no chance of any type of fracturing or structural failure. All pulleys and brackets have a "No Polishing" maintenance-free clear powdercoating. An adjustable stainless steel tensioning rod with chrome-moly rod ends and mounting hardware is also included. There are two pulley ratios available; Performance to increase horsepower by reducing accessory drag, with typical gains of 12-15 horsepower at the rear wheels and High Water Flow to increase cooling by speeding up water flow and fan speed, critical for low speed driving where most overheating occurs.Kits Include:
