Keep spark reaching the right cylinder in firing order with the Standard Ignition Distributor Rotor GB-311. Mounted on the distributor shaft, the rotor routes high-voltage current from the distributor cap's center terminal to each plug terminal as it spins. It's a direct-fit replacement for the 1960-1962 Mercedes-Benz 300, 1962 Mercedes-Benz 300D, 1960-1966 Mercedes-Benz 300SE, 1963-1967 Mercedes-Benz 300SEL, 1960-1963 Mercedes-Benz 300SL, 1960-1965 Volkswagen Beetle, 1960-1964 Volkswagen Karmann Ghia, and 1960-1963 Volkswagen Transporter — see the Buyer's Guide tab for engine details.
Signs the rotor may need replacing include hard starting, rough running, or misfires traced to a worn, cracked, or carbon-tracked rotor. Diagnose the cause before replacing.

This part cross-references / interchanges with the following part numbers:
What does the distributor rotor do?
Mounted on the distributor shaft, it routes high-voltage current from the cap's center terminal to each plug terminal in the firing order as it spins.
What are the segments made of?
The rotor uses solid brass segments, which provide better conductivity and a higher-voltage spark to the plugs.
What material resists carbon tracking?
A high-grade dielectric alkyd resists dirt sticking, which decreases carbon tracking for extended service life.
Which vehicles does GB-311 fit?
It's a direct-fit for the 1960-1962 Mercedes-Benz 300, 300D, 300SE, 300SEL, 300SL, plus the Volkswagen Beetle, Karmann Ghia, and Transporter. See the Buyer's Guide tab.
What are signs the rotor should be replaced?
Hard starting, rough running, or misfires traced to a worn, cracked, or carbon-tracked rotor. Diagnose the cause before replacing.
