Description
If you’re pushing your M8 to higher RPMs and demand precision valve timing without the slop of a stock chain drive, the S&S Cycle 475G cam kit eliminates timing chain lash and enables higher cam lifts by reversing rear cam rotation. This gear drive system transforms your valve train into a tight, responsive mechanical system that rewards aggressive builds with increased operating clearance and accuracy you can feel at the track.
Installation requires professional-level equipment and expertise—this is a fabrication job, not a weekend bolt-on—but the payoff is a valve train built for serious performance without the guesswork of timing chain stretch.
