WP475-M8 Drop-In
Description:
The WP475-M8 Harley-Davidson Milwaukee-Eight camshaft is Ward Performance’s highest-output drop-in option. Strong torque hits by 2,500 RPM, surges past 3,000, and pulls hard to 6,000—delivering the passing power serious street riders expect without sacrificing low-speed manners. A crisp, uneven idle makes its presence known, yet the cam stays civil for long highway miles. Install with adjustable pushrods, and unlock the M8’s full potential.
