It is a direct-fit replacement for the listed applications, including the 1990-1996 Chevrolet C60 Kodiak, 1991-1996 GMC C6000 Topkick, 1992-1996 GMC C7000 Topkick, 1997-1998 Chevrolet C6500 Kodiak and 1997-1998 GMC C7500 Topkick.

The rotor mounts on the distributor shaft and turns with it. It carries current from the distributor cap's center brush to each outer terminal in turn.
Signs a rotor may need replacing include a burned or eroded tip, cracks or carbon tracking on the body, misfires, rough running or hard starting. The cap, plug wires or coil can cause the same symptoms, so diagnose the cause before replacing parts. Inspect the distributor cap during the same service.

What does a distributor rotor do?
It turns with the distributor shaft and routes high-voltage current from the cap's center brush to each outer terminal in turn, sending spark to the correct cylinder.
Which vehicles does the Standard DR-330 fit?
It is listed for Chevrolet and GMC applications, including the 1990-1996 Chevrolet C60 Kodiak and 1992-1996 GMC C7000 Topkick. See the "Vehicles it fits" section for the full list and engine details.
What are the benefits of the brass segment?
The solid brass segment resists pitting and erosion for extended life. Its noise-suppressing coating helps prevent interference with the radio and other electronic circuits.
How does the rotor stay in position on the shaft?
It uses shaft retention clips for a proper fit on the distributor shaft. A stainless steel spring keeps positive contact with the distributor cap brush.
What are signs of a worn distributor rotor?
A burned or eroded tip, cracks, carbon tracking, misfires or hard starting may indicate a worn rotor. The cap, wires or coil can cause the same symptoms, so diagnose the cause first.
