S&S CYCLE Chain Drive Cam - 510C - Twin Cam 106-4380

Timing chain lash robs your Twin Cam engine of precision and limits your cam lift potential. The S&S Cycle Chain Drive Cam Kit eliminates that slack entirely by replacing your stock chain drive with a gear-driven system that delivers rock-solid valve timing accuracy and unlocks higher lift profiles. You'll feel the difference in throttle response and mid-range power where it matters most—between 3000-5000 RPM.

This is a professional-level upgrade designed for builders who demand absolute control over their engine's breathing. By reversing the rear cam's rotation direction, the kit creates additional clearance between cam lobes, allowing for more aggressive valve events without interference. Installation requires a hydraulic press and fabrication skills, but the payoff is a significantly sharper, more responsive engine that holds its timing regardless of load or RPM.
