S&S Cycle Easy Start 640 Gear Drive Cam Kit - 106-4840
  • 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 4-gear set 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
  • For 95/96/103/110 cubic-inch engines
  • Compression ratios from 10.5:1 to 11.5:1
  • Strongest from 3,000-6,000 rpm
  • High-lift springs required
  • Made in the U.S.A.
