Restore exhaust flow and support cylinder head performance with this Kawasaki STX-15F 1500 Exhaust Valve Kit for applicable 2007–2019 models.

Why Replace Exhaust Valves?

Exhaust valves live in one of the hottest parts of the engine. Over time, heat cycles and normal wear can reduce sealing performance. As a result, engines may develop compression loss, rough operation, harder starting, or reduced output.

Replacing exhaust valves during service helps restore sealing and supports long-term engine reliability.

Completing a Full Valve Refresh?

If you’re rebuilding the cylinder head, pair this kit with the Kawasaki STX-15F 1500 Intake Valve Kit or move up to the Complete Valve Kit to service both intake and exhaust sides together.

For additional top-end components, you may also want the Complete Top End Gasket Kit or the Complete Gasket & Seal Kit.
