S&S, set of 570G (IOG) gear-driven camshafts

.570" valve lift. IOG = gear-driven camshafts with internal and external drive gears. Complete kit with installation hardware, bearings and gasket.
Direct fit for 88" to 103" models with 9:1 to 10:1 compression ratio. Overall power increase between 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 does 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 fit of the stock camshaft gears. The only drawback 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 additional 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 camshafts, adjustable pushrods (such as MCS 503573) are required to compensate for the smaller base circle of these camshafts.
Note: Material may need to be removed 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: Factory beehive-type valve springs on 04-17 Dyna; 04-17 Softail and 04-16 Touring models support valve lifts up to 590" and a valve seat force of 160 lb, up to 6200 RPM. Running above 6200 RPM or with lifts above 590" will require high-performance valve springs.
