Increase performance at an affordable price, reusing many stock components. Bolt-in cams do not require head work. When using 1999-2006 chain drive cams for lifts over .510", S&S strongly recommends that the stock chain drive be upgraded to the S&S gear drive, the latest S&S forged cam plate and oil pump kit ZPN760604 or to the ZPN756295 (OEM 25284-11) hybrid plate. This kit updates the problematic spring loaded chain tensioners to reliable hydraulic tensioners and also upgrades the oil pump.
Easy Start cams start any engine regardless of displacement or compression ratio, using your stock starter. Consequently, they save your starter and battery. They work automatic, no buttons to push. The two exhaust cam lobes are equipped with a spring loaded compression release lobe on the "heel" of the cam at the point where the valve would normally be fully closed. The lobe holds the exhaust valve open slightly at cranking speed. This releases some of the compression, making the engine much easier to crank. 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. Easy Start cams have been tested for 100,000 accumulative starts and over 150,000 road miles without breakage or compression release failure.
S&S chain drive camshaft kits contain front and rear cam, gear cover gasket, bearings, retaining ring, o-ring, thread lock and instructions.

Notes: Early 1999 models may require the seperate purchase of ZPN 700835 splined cam sprocket. Stock valve springs in 1999 thru 2004 Twin Cams can handle cams with valve lifts as high as .515". Stock valve springs in 2005 thru 2017 Twin Cams can accommodate valve lifts up to .590". The OES, 505C and 557 grind cams can be installed using the stock pushrods. However, we recommend S&S Quickee Adjustable pushrods ZPN752108 for easy installation of all S&S cams.

475 grind: Original Equipment Specification (OES) A bolt-in replacement cam with stock cam timing is designed for riders with stock engines. Does not require tuning. Bolt-in stock. Equivalent to OEM A-Grind.

509 grind: Designed as a bolt-in, high torque cam for 1999-2006 models. 180PSI cranking compression, no need for compression releases. For 88CID engines with stock compression ratio. Idle-4500
