Product Description

S&S CYCLE Camshaft Kit – 635 H.O. – Gear Drive – Twin Cam

Key Features

• Reverses the rear cam’s direction of rotation, providing additional operating clearance between cam lobes; as a result, higher cam lifts are possible
• High lift camshaft for modified engines with 106″ or greater displacement and compression ratios between 10.0:1 to 11.0:1
• Increases valve and timing accuracy by eliminating timing chain lash and loosely-fit stock chain drive
• Works with stock, unported heads, but S&S CNC ported heads are recommended
• Material must be removed from inner surface of the stock gear cover to install
• A hydraulic press and other professional level tools are required to install
• S&S requires that adjustable pushrod/cover kit be used
• Cam bearings and gaskets must be replaced when installing new cams
• Best power from 3000-6000 rpm
• This is not a bolt in camshaft kit
• Kit includes camshafts, inner gear, out gear drives, inner bearings, outer bearings, gaskets and instructions
• Made in the USA
• Installer must check coil bind, valve to valve clearance and valve to piston clearance.
• Due to the inherent characteristics of gear drives, you may experience more valve train noise.
