S&S CYCLE Cam - 475G - M8 310-1006A

If you're serious about maximizing cam lift and eliminating timing chain slop, a gear drive conversion delivers the precision and clearance you need. By reversing rear cam rotation and removing chain lash, S&S gear drive kits enable higher valve events while improving timing accuracy—critical for high-output M8 builds. You'll gain the operating margin to push performance boundaries that chain drives simply can't match.
