S&S, Easy Start 583 (CD) chain-driven camshaft kit

0.583" valve lift. CD = Chain driven crankshafts, complete kit with gasket and bearings.
Direct fitment. 88 to 103" engines with compression ratios between 9.7:1 and 10.5:1, and 106" to 124" engines with compression ratios of 9:1 to 10:1. Provides great power and torque from 3000 RPM. Range 1500-5000 RPM.
Easy Start Crankshafts 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 camshaft with a compression release spring integrated into the crankshaft. After starting, the compression release camshaft retracts by centrifugal force. The only difference is during starting, as you will now be able to start your Big Inch engine electrically with ease, without the need for large batteries and/or starter motors. A standard starter motor and battery are sufficient. When the engine is running, the crankshafts operate as normal crankshafts, with no loss of power, torque or anything else.
Note: Only the 551, 570, 583, 585, HP103 and MR103 series crankshafts are direct fit; the others may require clearancing and need high lift valve springs.
Note: Not compatible with kick-start models.
Note: Only crankshafts 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.
