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.
