Standard Ignition AL-171 distributor rotor for the 1980-1984 International Cargostar 5.7L and other vehicles carries the high-voltage spark from the center of the distributor cap to each spark plug terminal in turn.
Misfires, hard starting or a rough idle can point to a worn distributor rotor. Before you replace it, rule out the distributor cap, spark plug wires and spark plugs, since a worn set of those can produce similar symptoms.
The distributor rotor is a direct-fit replacement for the 1980-1982 International S1724 5.7L and the 1980-1983 International S1824 6.4L, and each takes one. Open the Buyer's Guide tab to check your exact model and engine.
