551 cams are bolt-in cams for 1999-’06 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.

Features:

• Start any engine regardless of displacement or compression ratio with a stock starter
• Save your starter and battery; tested for 10,000 starts without running battery down
• Allow for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance
• All chain-drive cams include installation kit
• All gear-drive cams include 4-gear set and installation kit
• For 88/95/96/103 cubic-inch engines
• Compression ratios below 10:1
• 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.
• Not for models with OEM compression releases.
• Made in the U.S.A.
