Help keep high-voltage spark reaching every plug on your classic with the Standard Ignition Distributor Rotor LU-300. It fits many vintage vehicles, including the 1963-1969 Ford Cortina, 1962-1974 MG MGB and 1958-1970 Austin Healey Sprite. See the "Vehicles it fits" section for the full list and engine details.
The rotor turns with the distributor shaft. It carries the coil's high-voltage current from the cap's center terminal to each outer terminal in firing order, which sends spark down the plug wires. Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control throughout production, from componentry to finished product.
- Dielectric alkyd: Uses high-grade dielectric strength alkyd that resists dirt sticking. Standard Ignition says this decreases carbon tracking for extended service life.
- Solid brass segments: Designed for better conductivity and a higher-voltage spark to the plugs.
- Shaft retention clips: Used where the application requires one, for the best fit and performance.
- Engineering background: Built on decades of Standard Ignition research and development in distributor caps and rotors.
Signs a rotor may need replacing include misfires, hard starting, a no-start condition, rough running, or a tip that is burned, eroded or carbon-tracked. Diagnose the ignition system before replacing parts.

Frequently Asked Questions
What does a distributor rotor do?
It turns with the distributor shaft and passes high-voltage current from the cap's center terminal to each outer terminal in firing order, sending spark to the plug wires.
Which vehicles does the Standard Ignition LU-300 fit?
It fits many classic vehicles, including the 1963-1969 Ford Cortina, 1962-1974 MG MGB and 1958-1970 Austin Healey Sprite. See the "Vehicles it fits" section for the full list.
What are the signs a distributor rotor may need replacing?
Common signs include misfires, hard starting, a no-start condition, rough running, or a burned, eroded or carbon-tracked tip. Diagnose the ignition system before replacing parts.
What are the rotor's contact segments made of?
Standard Ignition states that its distributor rotors use solid brass segments. They are intended to give better conductivity and a higher-voltage spark to the plugs.
How does the alkyd material help?
The rotor uses a high-grade dielectric strength alkyd that resists dirt sticking. Standard Ignition says this decreases carbon tracking for extended service life.
