Wood Performance Knight Prowler Camshafts for Harley Milwaukee-Eight 2017-Up M8

Built for riders who demand instant acceleration, these performance camshafts are engineered for the Milwaukee-Eight platform and deliver the kind of torque and horsepower that transforms throttle response from idle to the mid and upper RPM range. Designed by Wood Performance Carburetors and precision-manufactured by Andrews Products to exact specifications, these street-focused profiles were redesigned from the ground up to maximize real-world pull—two-up riding, heavy touring loads, mountain climbs, twisty roads, and hard launches.

• High-torque, high-horsepower camshaft upgrades for Milwaukee-Eight engines across a broad displacement range
• Strong low-RPM response with hard-hitting midrange power—ideal for touring, aggressive street riding, and quick acceleration
• Chain drive applications only (where specified)
• Some setups are true bolt-in options, while higher-lift/higher-duration profiles may require supporting valvetrain upgrades

Depending on your build and compression goals, options range from super high torque at low RPM for heavy two-up riding and instant roll-on power, to more aggressive profiles designed for higher compression and hot-rod performance with a strong, attention-grabbing idle. The focus is simple: torque, torque, and more torque—so you get there quicker.
