Περιγραφή

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 chain-drive cams include installation kit
All gear-drive cams include 4-gear set and installation kit
For 88/95/96/103 cubic-inch engines
Compression ratios below 10:1
Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
Due to the inherent characteristics of gear drives, you may experience more valve train noise.
