S&S 583 Cam Kit For Harley Twin Cam

Features:

• Available in chain or gear drive versions
• Quick installation reuse many stock components
• Camshafts that exceed the limits of the stock valve springs require the use of special high lift springs
• 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
• Quick installation and Easy Start Cams allow stock starter to start any engine
• Kit contains cams, gear cover gasket, cam bearings, and instructions
• 1999-2004 stock springs will handle camshafts with lift up to 0.510"
• If a camshaft with higher lift is installed, high performance valve springs capable of handling a greater lift must be used
• 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
• S&S Cycle chain drive cams are compatible with the stock splined chain sprocket used in 2000-06 Twin Cam 88 engines, but may be used in 1999 engines if the Harley-Davidson 2000-06 splined rear cam sprocket and appropriate 2000-06 sprocket spacer are used
• For lifts over .510" S&S strongly recommends that the stock chain drive cam be upgraded to the S&S Cycle gear drive or to the H-D part number 25284-08. This kit upgrades the problematic spring loaded chain tensioners to more reliable hydraulic tensioners, and also upgrades the oil pump
• 583 Camshafts are optimized for use in the Softail/Dyna lines, this cam makes horsepower and torque that you can feel all the way through the rpm range, making the most power right where you need it:1500-5000rpm

Note: Installation of S&S chain drive cams requires special tools. Attempting the cam change operation without these tools will be difficult, and damage can result which will not be covered under warranty.
