This is the factory 4-pole, 3-bolt camshaft sprocket (gear) for the 2005 LS2. This genuine GM part fits LS engines equipped with a 58x Reluctor wheel. This camshaft sprocket can be used with the C5R IWIS timing chain or other OEM style timing chain.
If you are installing this in an earlier LS1 or LS6 engine with the cam sensor at the back of the engine you will need a 2005 LS2 front cover, 2005 single pole cam sprocket, camshaft extension harness and 2005 LS2 chain dampener.
