WP580-M8

$345.00

Description:

Instant torque for big-bore baggers. The WP580-M8 Milwaukee-Eight camshaft shifts the WP550’s punch lower in the revs, lighting up 124–132 ci builds—and the H-D 131 crate motor—right off idle. Torque rolls in at 2,500 RPM, surges past 3,000, and holds strong to 6,000 RPM, with dyno numbers landing in the mid-160s for both horsepower and torque. A crisp, lopey idle hints at the .580" lift and revised timing, yet street manners stay civil for long hauls. Plan on upgraded springs, pushrods, and a proper tune; bolt it in, twist the throttle, and feel big-bore pull everywhere on the graph.

Key Features & Rider Benefits:

  • Early Power Delivery: Experience a significant boost in low-end torque and horsepower that comes on sooner than our original WP550 cam.

  • Broad, Usable Powerband: Delivers a powerful hit from 2500 RPM and continues to pull hard all the way to 6000 RPM, giving you incredible passing power and thrilling acceleration.

  • Big Bore Dominance: Specifically designed to maximize the potential of 124" to 132" big bore builds, with proven results in the 160s for both horsepower and torque.

  • 131 Crate Engine Drop-In: Makes a fantastic drop-in camshaft for the Harley-Davidson 131 crate engine, capable of producing horsepower and torque in the mid-150s with no other modifications.

  • Performance Sound: The WP580-M8 produces a nice, lopey idle, giving your M8 a distinctive performance sound that matches its power.
