S&S CYCLE Cam - 475G - M8 310-1010A

If you're running an M8 Harley and serious about maximizing valve lift and timing precision, a gear drive cam conversion eliminates the slop inherent in stock chain drives—giving you tighter valve events and the clearance to run aggressive cam profiles that stock geometry simply won't allow. S&S's 475G delivers the accuracy and durability you need for high-horsepower builds, while the reversed rear cam rotation opens up additional lobe clearance for higher lifts without interference. This is a fabrication-level upgrade that separates purpose-built engines from bolt-on modifications.
