This optional 5/8" 4-bolt pulley alignment spacer is intended for Small Block Ford Fluidampr applications and supports correct pulley positioning when required on 1975 and later engines. Sold individually, the aluminum spacer adapts the damper/pulley configuration to maintain belt alignment for older Ford small-block installations where spacer correction is necessary for proper accessory drive fitment.
