S&S, 570G (IG) gear-driven camshaft set

0.570" valve lift. IG = gear drive cam kit with inner gears installed only. An outer drive gear kit is required; if not available, it can be ordered separately as 531265.
Direct mount for 88" to 103" with 9:1 to 10:1 compression ratio. Overall power increase from 3200-5700 RPM.
The gear drive system is in fact a revolutionary, different and far more reliable construction. Especially in high lift/performance applications, compared with the factory chain drive design. A gear driven camshaft is stronger and will not suffer any of the mechanical problems associated with factory chain driven camshafts. The S&S gear drive kit will increase valve timing accuracy and therefore power, by eliminating timing chain slack and the loose-fitting stock cam gears. The only downside of gear drive is that you may experience a slight increase in mechanical noise; this is why the factory uses a chain. It has no other mechanical advantage. As the chain guides and tensioner are removed, there is no longer any chance of these parts failing and damaging other parts of the engine. The S&S gear drive kit reverses the rotation of the rear camshaft, providing greater operating clearance between the cams. As a result, greater cam lifts are possible with S&S gear driven camshafts.
Note: With the exception of the 475G and 510G cams, adjustable pushrods (such as MCS 503573) are required to compensate for the smaller base circle of the camshaft of these cams.
Note: The S&S gear drive installation support kit (MCS 503566) can be ordered separately if required. The kit includes a cam bearing set, retaining ring and gasket.
Note: It may be necessary to remove material from the inner surface of the factory gear cover before installing the S&S outer drive gears (which are required and available as 503577).
Note: The factory beehive valve springs on Dyna 04-17; Softail 04-17 and Touring 04-16 models support valve lifts up to 0.590" and a valve seat force of 160 lb, up to 6200 RPM. Running above 6200 RPM or with lifts greater than 0.590" will require high-performance valve springs.
