Help keep high-voltage spark reaching every cylinder of your classic with the Standard Ignition Distributor Rotor AL-99. It is a replacement for a long list of vintage applications, including the 1946-1949 Chrysler Town & Country, 1948-1950 Packard Super Eight, 1952-1955 DeSoto Firedome, 1955-1956 Hudson Hornet and 1956 Studebaker Golden Hawk, plus Dodge, Jeep, Nash, Kaiser, Lincoln and Plymouth models. See the Buyer's Guide tab for the full list and engine details.

The rotor turns with the distributor shaft. It carries the ignition coil's high-voltage current from the center of the distributor cap to each spark plug terminal in firing order.

  • Original equipment ignition maker: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains complete quality control throughout manufacturing, from componentry to the finished product.
  • Dielectric alkyd: High-grade dielectric strength alkyd resists dirt sticking. This decreases carbon tracking for extended service life.
  • Solid brass segments: The segments are designed for better conductivity and a higher-voltage spark to the plugs.
  • Shaft retention clips: Clips are used where the application requires them, for proper fit and performance on the distributor shaft.

Signs that a distributor rotor may need replacing include misfires, hard starting, rough running, or a rotor tip that looks burned, worn or cracked. If a worn rotor is the cause, this part replaces it. Inspect the distributor cap at the same time.
