GEAR DRIVE CAMSHAFTS KITS FOR 07-UP BIG TWIN ENGINES

The patented S&S Gear Drive Cams are a must in order to achieve the full potential from high performance Harley-Davidson® Twin Cam 88® engines.  Since the chain drive system used in stock Twin Cam 88 engines is not adequate to accurately control valve action at high RPM when using high lift cams and high performance valve springs, a different system was needed.  The S&S Gear Drive System was developed to improve performance and to eliminate potential engine damage caused by failure of the chain and tensioner system.  S&S Gear Drive Camshaft Kits improve valve timing accuracy by eliminating timing chain lash as well as variations caused by the loose fitting stock cam drive sprockets.  All stock chain drive components are replaced with S&S Gear Drive Cams and outer drive gears.  This simple, effective solution provides two to three more horsepower simply by eliminating chain drag, and allows more aggressive cam profiles and increased valve spring force to be used.  Call for pricing.  Installation options also available.
