    The Derale 31540 is a 2-1/4 inch aluminum fan spacer for belt-driven mechanical cooling fans. It moves the fan forward on the water pump shaft so the blade sits in the correct position relative to the radiator and fan shroud, which improves airflow through the core. The spacer is machined from aluminum to keep rotating weight low.

    • Spacer length: 2-1/4 inch
    • Material: Aluminum
    • Application: Repositions a belt-driven fan forward toward the radiator
