About This Product

This return spring for the starter solenoid plunger is a small but vital component for ensuring your Harley's starting system operates correctly. A worn or broken spring can lead to poor starter engagement or sticking, so keeping a fresh one on hand is always a good idea. This spring fits 1965 through 1988 Big Twin models and 1967 through 1980 XL Sportsters. It is a direct replacement for OEM part number 31440-65 and is also listed under MCS number 506810. This item is sold as a set of 5, ensuring you have spares for future maintenance or multiple projects in the shop.

Manufacturer part number: 506810.
