WP550-M8

$345.00

Description:

  • Meet the horsepower benchmark. The WP550-M8 Harley-Davidson Milwaukee-Eight camshaft is our original big-bore weapon, built for 124–132 cu in engines running 11.5-to-12:1 compression. A savage idle tells the story; crack 3,000 RPM and it pulls hard to 6,500 RPM, posting 170-plus HP with the right intake and exhaust. Street manners below 2,500 RPM stay intact, but this is not a bolt-in swap—plan on upgraded springs, pushrods, and a pro tune to let the cam breathe and dominate.

Key Features & Rider Benefits:

  • High Horsepower Focus: Specifically designed to produce very good mid to high RPM horsepower.

  • Aggressive Sound & Performance: Delivers an awesome aggressive lope at idle and a strong pull from 3000 to 6500 RPM.

  • Streetable Manners: Impressively maintains good drivability and low RPM manners despite its aggressive nature.

  • Durability by Design: Features a .550" valve lift for great valve train durability.

  • Beat Your Buddy: This cam was engineered to give you the edge and make serious numbers.
