The Rush SR is designed for longevity, but extended operation requires scheduled replacement of safety-critical and wear components. A warning light is shown every 12,000 mi (approx. 150 hours) to indicate the engine and gearbox should be rebuilt. See [dash-alarms.md](../at-the-track/aim-dashes-and-smartycams/dash-alarms.md "mention").
