Measuring 2.25-inches long, the spacer is vital for keeping fan blades close to the radiator for the most efficient job of drawing cool air through the core. Precision made by Scott Drake Enterprises from billet aluminum as a direct reproduction of the original, the fan spacers are available in either the original-style natural finish (C4AZ-8546-A) or brightly polished (C4AZ-8546-P).
