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

.570" valve lift. Gear driven camshaft with internal gears only.
88" to 103" with compression ratio from 9:1 to 10:1. Overall power increase from 3200-5700 RPM.
The Easy Start camshafts make starting easier by reducing the build-up of compression pressure in the cylinders during starting. This is achieved by slightly lifting the exhaust valve off its seat, by means of a spring-loaded compression release lobe inside the camshaft. After starting, the compression release lobe retracts through centrifugal force. The only difference is during starting, as you will now be able to start your Big Inch engine electrically with no effort, without the need for large batteries and/or starter motors. A standard starter motor and battery are sufficient. When the engine is running, the camshafts operate as normal cams, with no loss of power, torque or anything else.
Note: The installation kits required for Easy Start camshafts are only included in the complete kits. They are available separately from S&S for this kit as 503566. Compatible only with gear-driven models.
Note: There is no direct-fit Easy Start cam profile for these 99-06 Twin Cam models. All will require and/or may require disassembly (clearancing) and high lift valve springs.
Note: Not compatible with kick-start models.
Note: Camshafts manufactured before January 2010 will require adjustable pushrods.
Note: Below 900 RPM a clicking sound may be heard. Adjust the idle speed to 1000-1100 RPM.
