The perfect overall choice for 111" Thunderstroke Motors, giving smooth rideability and crisp throttle responsiveness. These cams also work great in 116" Touring bikes, producing more low and mid-range power than Indian STG III cams, the 558's are a great fit for low to Mid RPM cruising, roll on power and economy.
A proper tune is needed to maximize power, economy and throttle response.
A Lloyd'z Adaptive Fuel Controller can be used with the 558 cams, however for maximum results ECU tuning is recommended.
To avoid damage to your engine we highly recommended adding our Spring Kit for all Indian models from 2014 to 2018 when adding our IMC-558, 585 or IMC-595 cams.
