761002 Replacement Spring Kit

This mechanical advance unit from American Prime Manufacturing is designed for Harley-Davidson ignition systems requiring a mechanical advance, including traditional points and electronic setups like the Dyna S or Daytona TwinTec VT-I. The assembly utilizes a stainless steel shaft and plate for corrosion resistance and precision. The weights are heat-treated and coated with specialized polymers to ensure smooth movement, while the springs are wound from phosphate-coated music wire and white-plated for resilience. By maintaining exact tolerances, this unit helps achieve a stable idle and improved throttle response. This component is an essential replacement for maintaining ignition timing accuracy. Please note the cam is sold separately.
