Convert your cylinder head to long-life Black Diamond™ stainless intake valves and refresh the valvetrain in one kit. Designed per application to boost durability and reduce wear compared to OEM titanium components.
Upgrade durability where it matters most. The Kibblewhite Intake Stainless Conversion Valve and Spring Kit is built to convert your cylinder head to long-life Black Diamond™ stainless steel intake valves while renewing the supporting valvetrain components. The result is a stronger, longer-lasting intake setup that helps reduce frequent valve-related service compared to OEM titanium parts.
If you ride hard, race regularly, or simply want a more reliable top end, this conversion kit helps extend valvetrain and intake component life—reported up to 4x over OEM titanium—so your engine can stay consistent for longer between rebuilds.
