Description
Timing chain lash and wear compromise valve timing precision on Twin Cam engines, directly impacting power delivery and engine reliability. The S&S Cycle Cam Kit with 4 gears replaces your stock chain drive with a rigid gear drive system, eliminating deflection and enabling higher cam lifts for aggressive valve events. If you’re building a high-performance engine or seeking measurable gains in the mid-range, this is essential upgrade hardware.
The gear drive reverses the rear cam’s rotation, creating additional clearance between cam lobes—a design feature that allows manufacturers and tuners to specify more aggressive lift profiles without risk of interference. You’ll experience stronger performance in the 3200-3700 rpm band, where most riders spend their time accelerating and cruising.
