Excellent for under-the-hood applications, Dupli-Color Engine Enamel will perform to the most rigorous standards of racing, street rod, and vehicle restoration enthusiasts.

Installation Notes:
This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension. Not recommended for sustained use above 5,000 RPM engine speed. ((Check instructions section for finding belt sizes and wiring)). If you DO NOT use the correct shorter belt, this will result in very low to no output and create extra work load for the alternator.
