Distributor Weight Pads

The Distributor Weight Pads by MSD IGNITION (MPN: MSD10064) are designed for tuning ignition timing in various engine applications. These pads are essential for engine builders and mechanics who seek precision and accuracy in optimizing distributor advance curves. They are suitable for both street engines and racing motors, allowing for effective modifications without the need to replace the entire distributor assembly.

These weight pads function by adjusting the spring tension and mass distribution within the mechanical advance mechanism, which directly affects the distributor rotor's advancement as engine RPM increases. By utilizing different pad weights, users can customize the advance curve to align with their engine's specific requirements, such as fuel octane rating and cam profile. The compact design ensures compatibility with standard MSD distributor assemblies.

Professional engine builders, vintage car restorers, and serious hobbyists will find significant benefits from using distributor weight pads. These components provide a cost-effective solution for tuning ignition timing, enhancing performance, and ensuring repeatable results during dyno testing and street validation.
