Andrews EV59 Cam for 1984-1999 Harley Evolution Big Twin

Product Description

Andrews EV59 Camshaft for Harley Evolution Big Twin

Build serious performance into your Harley-Davidson Evolution Big Twin with the Andrews EV59 Camshaft. Designed for modified 80ci to 88ci engines, the EV59 features fast opening and closing ramps with increased lift and duration to deliver a broad powerband and strong midrange through upper-rpm horsepower.

With .560" intake and exhaust valve lift and 256°/260° duration at .053", the EV59 is intended for properly prepared performance engines rather than stock valvetrain combinations. Andrews high-lift valve springs and collars are required, while hydraulic lifters can still be retained. The EV59 is an excellent choice for modified Evolution engines looking for strong performance through approximately 6,000 rpm.
