Advance Weight Assembly Stainless

This high-quality advance unit is engineered for maximum reliability and durability. The base plate, shaft, and retaining pins are entirely made from corrosion-resistant stainless steel – ideal for long-term use under demanding conditions.

The flyweights are manufactured from hardened steel and coated with a specially formulated polymer. This reduces friction, provides reliable protection against heat saturation, and enhances the mechanical efficiency of the component. Zinc-plated springs ensure consistent return forces and precise operation over time. A central mounting bolt is included.

The centrifugal ignition advance unit is designed for both custom builds and the optimization of existing ignition systems. Starting in the late 1970s, Harley-Davidson introduced electronic ignitions, which, due to initial reliability issues, led many riders to revert to proven mechanical points ignitions.

This kit is perfect for motorcycles with points ignition (model years from 1970), for upgrading early electronic ignitions (1978-1979), or for converting back to a simple and reliable points ignition setup. It fits all Harley-Davidson models from 1970 up to the introduction of the Twin Cam series.
