S&S Cycle Inner Cam Gears
S&S Cycle offers inner cam gears for a variety of Harley-Davidson© street bikes from 2006 and up. This is the gear located on the inside of a camshaft, directly connected to the camshaft itself.

Essentially, an inner cam gear is the primary gear on the camshaft that engages with the timing system to rotate the camshaft properly. These OE-style replacements are manufactured from factory materials and specifications to ensure proper fitment and long-lasting performance.

COMP Cams Valve Springs
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential.
