551 cams are bolt-in cams for 2005-up engines. Cams 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. Not all grinds are available in the chain drive version. To get the best performance from a performance cam installation, a high flow intake and exhaust system is also recommended. 2005-'06 can use stock valve springs while 1999-'04 will need special valve springs. Designed for engines with 96 to 106 CID and 9:1 to 9:9 compression this is a bolt-in cam set designed for stock or mildly modified touring bikes. 551 cams are not recommended for compression ratios of 10:1 or greater. Greatly improves low-end and midrange torque, strongest from idle-4000rpm. Quick installation and Easy Start® Cams allow stock starter to start any engine. Kit contains cams, gearcover gasket, cam bearings, and instructions.
