S&S Cycle 570C Chain Drive Camshaft Kit

• Chain drive version camshafts increase performance at an affordable price

• 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, gearcover 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.

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

• 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

• 570 Camshafts are designed for 88 to 103 CID engines with compression ratios between 9:1 and 10:1 this cam will provide a nice power increase across the entire power band. 3200-5700 rpm. Excellent bolt-in for overall power on 103″.
