Distributor Rotor for 1946-1949 Cadillac Series 61 & More - Standard Ignition DR-142

Help deliver high-voltage spark to every cylinder in firing order with the Standard Ignition Distributor Rotor, part number DR-142. It is a replacement rotor for many classic pre- and post-war vehicles, including the 1937-1942 Cadillac Series 75, 1937-1938 Chrysler Imperial and 1949-1954 Pontiac Chieftain. See the "Vehicles it fits" section for the full list.

The rotor turns with the distributor shaft. It carries voltage from the coil's center terminal across to each spark plug terminal inside the distributor cap. A burned, pitted or cracked rotor, or one showing carbon tracking, is a common candidate for replacement during an ignition tune-up.

• Quality control: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains quality control through the whole manufacturing process, from components to finished product.
• Dielectric alkyd: Standard Ignition's high-grade dielectric strength alkyd resists dirt sticking. This decreases carbon tracking and is intended to extend service life.
• Solid brass segments: The rotor's solid brass segments are designed for better conductivity and higher voltage spark to the plugs.
• Retention clips: Standard Ignition's rotor uses shaft retention clips where the application requires them, for proper fit and performance.

If a worn rotor is the cause of your misfire or rough running, this rotor replaces it. Diagnose the ignition system before replacing parts.
