Standard Ignition GB-311 Distributor Rotor

Distributor Rotor for Classic Mercedes-Benz and Volkswagen

Standard Ignition GB-311 is a distributor rotor for classic ignition systems that need stable spark transfer and consistent fit. It is built with a dielectric-strength alkyd body to help resist dirt buildup and reduce carbon tracking, supporting longer service life in older distributor assemblies.

Compatible With 1960-1967 Mercedes-Benz 300SL, 300SE, 300SEL, and 300D applications, as well as 1960-1965 Volkswagen Beetle distributor setups. The GB-311 is a direct replacement rotor for service work on these vintage ignition systems.

Key Features

• High-grade alkyd construction helps resist dirt sticking and carbon tracking
• Solid brass segments improve conductivity for stronger voltage transfer to the plugs
• Shaft retention clips are used where required for proper fit and performance
• Built for distributor service on classic Mercedes-Benz and Volkswagen applications
• Standard Ignition GB-311 supports reliable ignition system maintenance

Detailed Description

This distributor rotor is engineered for older ignition systems where consistent electrical transfer matters. The brass segment design supports efficient spark delivery, while the insulating body helps maintain performance in demanding under-hood conditions. Standard Ignition GB-311 is a practical replacement for vintage Mercedes-Benz 300SL, 300SE, 300SEL, and 300D models, plus select Volkswagen Beetle distributor applications.

This part cross-references Delphi TL470 for the same application.

Common Issues It May Address

• Weak or inconsistent spark delivery from a worn rotor
• Carbon tracking inside the distributor
• Misfire caused by poor rotor conductivity
• Hard starting related to ignition wear
• Distributor service needs on classic Mercedes-Benz and Volkswagen vehicles

Installation Notes and Tips

• Verify distributor part number and rotor style before installation.
• Inspect the distributor cap, terminals, and shaft for wear or corrosion.
• Confirm the rotor seats correctly on the distributor shaft and retention clip, where used.
• Replace related ignition components if carbon tracking or terminal wear is present.

Quality Assurance

Standard Ignition uses decades of ignition-system development in the design of its distributor caps and rotors. GB-311 is built to support dependable fit and electrical performance in classic applications.
