That should come with the pulley, I had mortal HELL with that pulley, it caused my engine to see knock about 4500 RPM an it ran like ****, I spent thousands of dollars trying to figure out what was causing the knock sensors to pull timing. I even put it on the Dyvo. No codes etc other than random missfire. I finally pulled it of and went back to stock.. Ran Perfect I guess the elastomeric part wasn't bonded good ,just make sure it is installed correctly and is up to spec..
