Thunderstroke 111 Performance Cams

A Stage 2 upgrade means new camshafts. A camshaft is a mechanical part of a motorcycle engine that opens and closes the engine’s intake and exhaust valves. An upgraded cam offers a higher, longer duration lift that’s ideal for filling the combustion chamber with the optimal amount of air and fuel to create more power. These cams unleash up to 13% more horsepower and up to 7% more torque* than a stock Thunderstroke 111 ci engine. Enjoy responsive, punchy acceleration from a stop and plenty of no-lag passing power at highway speeds. With this kit, you’ll never compromise reliability or ride quality. Plus, Indian Motorcycle stands behind every accessory with warranty protection and the guarantee that you'll never void your motorcycle’s warranty when you install a factory-backed stage kit. These Stage 2 Performance Cams must be installed in-conjunction with a Stage 1 Air Intake and Stage 1 Slip-On Exhaust Kit (each required and sold separately). This kit includes a card with a unique calibration code that upgrades your Engine Control Module (ECM) software from a standard set-up. This software upgrade is required to ensure peak performance; therefore, dealer installation is required. *Increase results may vary depending on specific testing conditions. This accessory is not compliant on any Chief model for use in California.     Important Regulatory InformationThis item is only available for purchase and installation at your dealer.
