Frequently Asked Questions

Why should I upgrade from the stock oil control valve?

The factory check ball retainer is formed steel that can fatigue and crack over time, sending metal chips through your oil system and potentially causing engine damage. This S&S assembly uses a machined retainer to eliminate that risk.

Is this a bolt-in replacement?

Yes — it installs in place of the factory oil control valve assembly with no modifications required.

What engines does this fit?

This part is for oil-cooled Harley-Davidson M8 engines only. Verify your engine type before ordering.

Is there a warranty?

Yes — S&S backs this assembly with a lifetime warranty for as long as you own the motorcycle.
