Frequently Asked Questions

Will this fit my Sportster before 2003?

Is this the same as the factory Harley part?

Yes — SMP manufactures this as a direct OEM replacement meeting Harley specifications.

What does a neutral safety switch do?

It prevents engine start unless the transmission is in Neutral or the clutch is pulled, protecting against unintended bike movement.

Do I need any tools to install this?

Basic hand tools and access to the transmission area are required. Consult your service manual for exact installation steps.

How long does this typically last?

With hardened high-carbon steel internals, it's designed for the life of the bike under normal riding conditions.
