Andrews M554 Cam for 2017-2026 Harley M8

Product Description

Andrews M554 Cam for Harley Milwaukee-Eight

Build serious torque and horsepower from a high-performance Harley-Davidson Milwaukee-Eight with the Andrews M554 Cam. Designed for larger-displacement engines with increased compression and cylinder head work, the M554 delivers a broad, aggressive powerband while maintaining strong torque throughout the usable street and performance RPM range.

The M554 is an excellent choice for 124" and 128" big-bore combinations with head work and higher compression, and can also work well in properly matched 117" engines installed in lighter motorcycles. With .550" intake and exhaust lift, 226°/256° duration at .050" and an operating range of approximately 1,600-5,500 RPM, this cam is designed for performance-oriented builds where increased airflow and upper-range power are priorities. High-lift valve springs are required.
