S&S Cycle 635C Chain Drive Camshaft Kit

• Most S&S cams have higher lift than stock and are designed to take advantage of the extra flow of ported stock heads or S&S Super Stock heads

• Due to the high lift of these cams, S&S adjustable pushrods are recommended

• To get the best performance from a performance cam installation, a high flow intake and exhaust system is also recommended

• Great way to increase performance at an affordable price

• Quick installation – reuse many stock components

• Kit contains 635 camshafts, Installation Kit: gear cover gasket, bearings, retaining ring, o-ring, thread lock, Instructions

• 2005-up stock valve springs will handle camshafts with lift up to 0.585″

• If a camshaft with higher lift is installed, high performance valve springs capable of handling a greater lift must be used. Cams with over 0.585″ of lift will cause interference between the valve spring top collar and the valve seal with stock cylinder heads

• 635 Camshafts are High lift cams for modified engines with 106″ or greater displacement and compression ratios between 10.0:1 and 11.0:1

• Works well with stock, un-ported heads, but S&S Cycle CNC ported heads are recommended. Best power from 3000-6000 rpm

• This is not a bolt-in cam set

• High-lift springs and clearance checks are required
