hydraulic roller lifters issues

Checked with Comp and they are saying all of their roller cams require the bronze gear. I have heard that they wear quicker than the stock gear.

If you have an austentic core and I'm almost 100% sure your do--then NO bronze gear required. Call and ask for Chris Mays at Comp Cams. J.Rob
