This Genuine GM Camshaft Timing Sprocket / Gear is used in GM LS-Series engines that are being swapped from the single-bolt cam to the older three-bolt cam design. When doing this swap, you will also need ARP #134-1003 Camshaft Bolts. This gear mounts to the camshaft via 3 three bolts and has the 4X reluctor (4 raised portions /poles for cam position sensor to read).
This camshaft sprocket can be used with the IWIS timing chain or other OEM style timing chains. It is also found in our VVT Delete Kit (click here to see it.)
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 1x cam sprocket, camshaft extension harness, and 2005 LS2 chain dampener.
