Upgrade your Classic Mini or Moke's performance with our Steel Water Pump Pulley Heavy Duty. Unlike the stock water pump pulley, which is made from sheet metal, this Cooper S pulley is an oversized casting 4.57" wide, designed for total reliability. Its larger diameter effectively slows down the water pump at higher RPM, saving horsepower and improving cooling. At Mini World Australia, we pride ourselves on providing top-quality parts to enhance your classic cars, ensuring they run smoothly and efficiently. Join us in our passion for perfection and give your Mini or Moke the attention it deserves.
