These precision machined aluminium pulleys are the ultimate in design, function and appearance. These units really add impact to the looks of your high performance small block Chevrolet. The upper (water pump) aluminium pulleys require special bolts for installation; use Part No. 50 4000.
CAUTION: Because aluminium pulleys must be made thicker than a steel pulley, the centre shaft on the water pump may not protrude through the pulley to properly support a fan. If the centre shaft of the water pump does not reach into the centre hole of the fan, do not use it. |
