WP586-M8

$345.00

Developed for the H-D 135 Kit. The WP586-M8 is Ward Performance's hot street/strip camshaft, purpose-built for 130 to 143 cubic inch engines running 11.5:1 or more compression. An awesome lope at idle announces its intent; from 3,000 RPM to 6,800 RPM it delivers relentless top-end pull for the strip and aggressive street riding. This is not a bolt-in swap — plan on upgraded springs, pushrods, and a proper tune to let the cam do its work.

Key Features & Rider Benefits:

  • Hot Street/Strip Performance: Purpose-built for aggressive street riding and the strip with relentless top-end pull.

  • Developed for SE 135 Kit: Optimized for the Harley-Davidson Screamin' Eagle 135 kit, 130" to 143" big bore engines.

  • Awesome Sound Profile: Delivers an awesome lope at idle, announcing its performance intent before you twist the throttle.

  • High RPM Dominance: Effective from 3,000 to 6,800 RPM, pulling hard where other cams fall off.

  • High Compression Ready: Designed for 11.5:1 and higher compression ratios to maximize power output.
