Andrews EV38 Cam for 1984-1999 Harley Evolution Big Twin

Product Description

Andrews EV38 Camshaft for Harley Evolution Big Twin

Increase midrange and upper-rpm performance in your Harley-Davidson Evolution Big Twin with the Andrews EV38 Camshaft. Designed for street and performance applications, the EV38 provides stronger midrange and top-end power while retaining good street manners and compatibility with stock valve springs on properly set up engines.

The EV38 uses a .495" intake lift and .500" exhaust lift with a longer exhaust duration to help broaden the powerband and manage engine heat. Andrews designed the cam as a bolt-in option for lighter motorcycles such as FXR models, making it an excellent choice for performance-oriented Evolution builds that need stronger acceleration without an excessively aggressive valvetrain setup.
