Standard Ignition Distributor Rotor P/N:LU-324
Keep high-voltage spark routed to the right cylinder with the Standard Ignition Distributor Rotor LU-325. Mounted on the distributor shaft, the rotor spins inside the cap and directs the coil's spark to each plug terminal in firing order — a worn or carbon-tracked rotor can cause misfires, hard starting, and rough running. It's a direct-fit replacement for a broad list of British applications, including the 1969-1971 Aston Martin DBS, 1972-1989 Aston Martin V-8, 1971-1974 Bentley Corniche, 1970-1973 and 1987-1994 Land Rover Range Rover, 1975-1985 Rolls-Royce Corniche, 1972-1973 Triumph Stag, and many more — see the Buyer's Guide tab for the full 26-vehicle list.

This part cross-references / interchanges with the following part numbers:
What does a distributor rotor do?
It rotates on the distributor shaft and directs high-voltage spark from the coil, through the cap, to each spark plug terminal in the correct firing order.
What are signs my distributor rotor may need replacing?
Common signs include engine misfires, hard starting, rough running, or a rotor tip showing carbon tracking, corrosion, or wear. Diagnose the cause before replacing.
Will the LU-325 fit my vehicle?
It fits 26 British applications across Aston Martin, Bentley, Land Rover, Rolls-Royce, Rover, and Triumph. Check the Buyer's Guide tab to confirm your exact year, make, and model.
What is the rotor made of?
It uses solid brass segments for conductivity and a high-grade alkyd body with strong dielectric properties that resists dirt sticking to reduce carbon tracking.
Should I replace the distributor cap too?
Caps and rotors wear together, so many technicians service them as a pair. Consult the vehicle service information for the recommended maintenance.
