1964-72 Chevy Truck 1" Thick Engine Cooling Fan Spacer with Mounting Hardware. Belt-driven fans work best when they are 3/4 in. to 1 in. from the radiator's surface. Whenever you remove an original equipment fan clutch from your engine, you need to add a fan spacer. This will bring the fan back into the "sweet spot" in the fan shroud opening. Always trust Ecklers for all your performance and restoration needs!
