Thunderstroke® Stage 2 Performance Cams

These cams unleash an extra 13% horsepower and over 7% more torque than a stock engine, and will not void the bike warranty. Used in conjunction with the Indian Motorcycle® Stage 1 Exhaust and either the Stage 1 Performance Air Cleaner or the High Flow Air Cleaner (each sold separately), the Stage 2 Cams increase the performance of the Thunderstroke® 111 motor. Install the cam kit for enhanced throttle response and significantly greater power across the powerband. Turn heads with a distinctive loppy idle.    This complete kit also conveniently includes the required Calibration Code that upgrades the Engine Control Module (ECM) software from stock to Stage 2, allowing this kit to be properly installed by your dealer. No additional software purchase necessary. Designed and made in the USA. Closed course racing only.   Each kit is designated with a warning triangle to indicate the restrictions that may apply.
