S&S 330-0339 635 Gear Drive Easy Start Cam Kit for Twin Cam 07-16

• Start any engine regardless of displacement or compression ratio with a stock starter
• Save your starter and battery; tested for 10,000 starts without running battery down
• Allow for easy start by initially reducing crank compression, but 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
• All gear-drive cams include inner and outer gears, and installation kit
• Gear-drive cams also available with inner gears only; intended for cam replacement for motors that have already been converted to an S&S gear-drive system
• High-power cam for modified engines, increase compression, high lift springs and large bore throttle body required
• For best results, requires ported heads and low restriction intake/exhaust
• RPM range 4000-6500
• Made in the U.S.A.
